What happens if the flu and RSV fuse into a single virus? Coloration One way the bull shark is able to conserve energy is that when the tidal flow changes, the bull shark uses the tidal flow in order to conserve energy as it moves downriver. Why Do The Great White Sharks Attack Humans? They can be found attached to the body surface, often in the axil region of the pectoral and pelvic fins. @`PpHhX80cbSR32sr [29][30] A golf course lake at Carbook, Logan City, Queensland, Australia is the home to several bull sharks. Alternatively, adult bull sharks weigh between 200 to 500 pounds as adults. The average male great white is 11 to 13 feet long (3.4 to 3.9 meters). Scientists Discover New World's Largest Omnivore --, Drone Footage Catches Boogie Boarder in a, The 8 Best Childrens Books About Sharks Available Today, The 10 Best Books About Sharks Reviewed and Ranked. Theyre both large sharks that can swim at fast rates of speed. Three of these attacks occurred in Matawan Creek, a shallow tidal river, only 40 feet (12 m) across, 1.5 miles (2.4 km) from bay waters, and over 15 miles (24 km) from the open ocean; not a location where any other large shark species would likely occur. Predicted weight (lb) for various fork lengths (ft) of 13 shark species from the western North Atlantic. In fact, these sharks are known to swim well below the surface in order to surprise-attack fish swimming above. Its coloring is also typically a It has not yet been conclusively resolved. Discover the answers to these questions along with others to learn more about these amazing ocean swimmers. (Fork lengt h ranges were taken from data presented in this study.) One or several bull sharks may have been responsible for the Jersey Shore shark attacks of 1916, which were the inspiration for Peter Benchley's novel Jaws. Great white sharks are social animals cruising through the ocean in schools, otherwise known as shoals. The mother gives birth after a 10-11 month gestation period at which point they become free-swimming and autonomous. [50] Coastal lagoons, river mouths, and other low-salinity estuaries are common nursery habitats. Bull sharks have been recorded in the Tigris River since at least 1924 as far upriver as Baghdad. According to the International Game Fish Association (IGFA), the largest bull shark caught on rod and reel weighed 771 lb. There are larger examples, but the most commonly seen examples in the wild fall within this range. However, the great white shark is the faster of the two. Heres why thats good. [34] They stayed at the mouth of the river independent of the salinity of the water. Life History The first sharks, cladodonts, are believed to be coming from the warm oceans back in about 400 million years ago. A 7.5 foot (2.25 m) white shark was captured two days after the last attack, 4 miles (6.4 km) from the mouth of Matawan Creek, and allegedly contained human remains in its stomach. This was found to be the reason that sharks are attracted to bright yellow survival gear rather than ones that were painted black. Copyright 2022 KnowSize.com All rights reserved. Humans are not, per se, on their menus. It can swim up to 35 mph while the bull shark reaches 25 mph. The Bull Shark is a member of the chordata, In taxonomy, its phylum is Chordata, the class is Chondrichthyes, and it belongs to the order Carcharhiniformes. Its wide range and diverse habitats result in many other local names, including Ganges River shark, Fitzroy Creek whaler, van Rooyen's shark, Lake Nicaragua shark,[6] river shark, freshwater whaler, estuary whaler, Swan River whaler,[7] cub shark, and shovelnose shark. Review of the Freshwater Sharks of Iran (Family Carcharhinidae). It is one of very few species that readily move into freshwater, and apparently can spend long periods of time in such environments (Sharks of the Genus Glyphis are also capable of living in freshwater). All rights reserved. Some skates (Rajidae), smooth dogfishes (Triakidae), and sandbar sharks (Carcharhinus plumbeus) regularly enter estuaries. The maximum length of bull sharks is believed to be about 3.5 m (11.5 ft) and the maximum weight, 230 kg (507 lb). The first dorsal fin is large and broadly triangular with a pointed apex. 2005). 16 - 25 years. [34] The young are not born with a high tolerance for high salinity, so they are born in fresh water and stay there until they are able to travel out. The bull shark is diadromous, meaning they can swim between salt and fresh water with ease. Remember that even within the same breed, there will be dogs that grow at a slower or faster pace than others. The largest weight of a whale shark registered is 47,000 pounds or 21.5 tonnes. Length (in) Select a fish Alligator gar Atlantic bumper Atlantic croaker Atlantic cutlassfish Atlantic midshipman Atlantic needlefish Atlantic sharpnose shark Atlantic List of all shark attacks by Bull shark Fatal Attacks 41 Unprovoked Attacks 179 Total Attacks 192 Bull shark is responsible for 192 attacks. to 2,500 lb. http://dx.doi.org/10.2305/IUCN.UK.2009-2.RLTS.T39372A10187195.en. [56] It was found that the young bull sharks synchronously moved downriver when the environmental conditions changed. [citation needed], After Hurricane Katrina, many bull sharks were sighted in Lake Pontchartrain. The bull shark name derives from its stout appearance and reputation for aggressive behavior. Lower jaw teeth have a broad base, and are narrow and triangular with fine serrations. How Do Sharks Know When Something Is Food Or Not. Bull sharks are very stout-bodied and have a blunt, rounded snout. Great white sharks are creatures of the open oceans and cannot live in fresh water. The Bull Shark is more dangerous to humans than most shark species. They can get up to 3.5 meters and are dark grey with a white belly. They have a varied diet and live in sub-tropical oceans (and freshwater rivers & lakes). Litters of the Bull Shark have 1 up to 13 babies and some of them migrate thousands of kilometers. [32], The bull shark is the best known of 43 species of elasmobranch in 10 genera and four families to have been reported in fresh water. Bull sharks are pale to dark gray above, fading to a pale cream color on their underside. The genus name Carcharhinus is derived from the Greek karcharos = sharpen and rhinos = nose. [35] This bottleneck may have separated the bull shark from the rest of the Elasmobranchii subclass and favored the genes for an osmoregulatory system. The average male would be about 7 feet long and weight about 200 pounds. [40], Bull sharks are able to regulate themselves to live in either fresh or salt water. 50 Bull Shark Teeth Photos and Premium High Res Pictures - Getty Images FILTERS CREATIVE EDITORIAL VIDEO 50 Bull Shark Teeth Premium High Res Photos Browse 50 bull shark teeth stock photos and images available, or start a new search to explore more stock photos and images. It has a tremendous size advantage. She owns and operates a small farm in upstate New York which she shares with three dogs, four donkeys, one mule, and a cat. The real winter soldiers behind the U.S.s newest national monument, See the beauty of Bhutan in a new cross-country trail, This new trail is revealing the wonders of Armenia to the world. [5] In India, the bull shark may be confused with the Sundarbans or Ganges shark. Bull sharks adapt well to being kept in captivity and are on exhibit in a number of public aquaria. Great white sharks can live up to 70 years while a bull shark lives 12 to 16 years. Is it possible to cure hot flashes? Males are slightly smaller, Adult male great white sharks are 11 to 13 feet long whereas females can be from The Bull shark is also not as readily identified as is the white shark or the tiger shark, and so may be responsible for a large fraction of the of the attacks that go unassigned to species (ISAF 2018). Some have been kept in tanks for over 15 years (Compagno et al. Pitties fall into the medium-sized category. After the first initial contact, they continue to bite and tackle prey until the prey is unable to flee. Juvenile bull sharks enter low salinity estuaries and lagoons as readily as adults do and use these shallow areas as nursery grounds. First dorsal fin originates over or slightly behind pectoral insertion, 3. Bull Shark Carcharhinus leucas In comparison to the streamlined look of most other sharks, bull sharks have a massive and stocky appearance because of their much wider body in relation to their length. They have broad, rounded snouts and small eyes (Compagno et al. Bull sharks are solitary for the most part. A 20-foot great white shark is likely to have a stronger bite force than an eight-foot bull shark. There is evidence that while they can breed in freshwater, they do not do so as regularly as they do in estuarine and marine habitats. When not working with her own animals and tending her farm, Krishna is helping other animal owners with behavior or management issues and teaching neighboring farmers about Regenerative Agriculture practices. Out of those, 41 have unfortunately been fatal which brings the percentage of fatal attacks to 21.35%. But bull sharks live in coastal areas where theyre likely to encounter humans. This is a distraction tactic; if the predator moves to eat the regurgitated food the bull shark can use the opportunity to escape. The maximum reported length of the bull shark is 400 cm (~13 ft) (Compagno et al. The pectoral fins are also large, broad and angular. The social behavior of these two sharks is another thing that sets them apart. A crocodile in South Africa was also reported to have consumed a bull shark. Ants make milk? The most obvious difference is size. Sharks come in all sizes. The young are about 70cm (27.6in) at birth. Would you believe a 448-pound, 4-ounce bull shark! 2005). Bull sharks are found swimming in the (relatively) shallow water near coastlines worldwide. [15], A female at the Shark Reef Marine Reserve, a private project in Fiji, In early June 2012, off the coast of the Florida Keys near the western part of the Atlantic Ocean, a female believed to measure at least 2.4m (8ft) and 360390kg (800850lb) was caught by members of the R.J. Dunlap Marine Conservation Program. Its large size, proclivity for freshwater, abundance and proximity to human populations, particularly in the tropics, makes it more of a potential threat than is either the White shark or the Tiger shark. Answer: The largest weight of a whale shark registered is 47,000 pounds or 21.5 tonnes. You can tell how old a shark is by counting the number of rings on its vertebrae. The second dorsal fin is significantly smaller. Other food items occasionally reported in bull sharks include sea turtles, dolphins, crabs, shrimp, sea birds, squid, and dogs. The males grow slightly smaller in size and commonly attain a length of roughly 7.4 ft (2.25 m), and weight of 210 lb (95 kg). Whilst it is theoretically possible for bull sharks to live purely in fresh water, experiments conducted on bull sharks found that they died within four years. Bony fishes and small sharks make up the vast majority of the bull sharks diet. A full grown bull shark can be around 10 to 11 meters in length. Yes, great white sharks are larger and heavier than bull sharks. Adult females are about 11.5 feet (3.5 m) long weighing 500 pounds (230 kg). Thats pretty tiny, considering that they will grow up to be as heavy as 75 lbs. Compagno, L., Dando, M., & Fowler, S. (2005) A Field Guide to the Sharks of the World. The IUCN Red List of Threatened Species 2009: e.T39372A10187195. [11], Bull sharks have a bite force up to 5,914 newtons (1,330lbf), weight for weight the highest among all investigated cartilaginous fishes. Are Tiger Sharks Dangerous Or Aggressive? [8], Some of the bull shark's closest living relatives do not have the capabilities of osmoregulation. Bull sharks are euryhaline and can thrive in both salt and fresh water. As for which shark is the most dangerous: that mostly depends on where you are. Many of the euryhaline fish are bony fish such as salmon and tilapia and are not closely related to bull sharks. Length at age and growth rates for 59 bull sharks, Carcharhinus leucas, collected from the northern Gulf of Mexico were estimated from the band patterns formed seasonally in the vertebral centra. They have been recorded in rivers hundreds of miles from the sea but are most commonly found in marine, estuarine environments close to shore (Simpfendorfer and Burgess 2009). Alternatively, a bull sharks snout is rounded. According to the International Shark Attack File (ISAF), bull sharks are historically responsible for at least 100 unprovoked attacks on humans around the world, 27 of which have been fatal. Size and style. They are also aggressive and territorial. The weight of a shark has a lot to do with its bite force. Females often bear mating scars on their flanks. [9], The bull shark shares numerous similarities with river sharks of the genus Glyphis, and other species in the genus Carcharhinus, but its phylogeny has not been cleared yet. The bull shark is a large active predator. [22] A large bull shark was caught in the canals of Scarborough, just north of Brisbane within Moreton Bay. Bull sharks can also tolerate hypersaline water as high as 53 parts per thousand (Simpfendorfer and Burgess 2009). The American crocodile is among the largest of all crocodiles but is still smaller than the Nile and saltwater crocodiles. The courting routine between bull sharks has not been observed in detail as of yet. Parasites [54], Behavioral studies have confirmed that sharks can take visual cues to discriminate between different objects. Furthermore, they are able to thrive in freshwater habitats. They are both consummate predators and they sometimes prey on the same animals. So, their proximity to people makes bull sharks more dangerous. A bull shark has a bite force of 1,300 PSI whereas a great white shark has a bite force of 625 PSI. However, theyve been known to swim with another bull shark when hunting. Where Does A Whale Shark Live? If a fight occurred between a bull shark and a great white shark, the great white shark would be the victor. No shark sets out to attack a human. [9][50], They are viviparous, born live and free-swimming. [53] In India, bull sharks swim up the Ganges, Bramaputra, Mahanadi, and other Indian rivers and have bitten bathers. [21] Several were sighted in one of the main streets of Goodna, Queensland, shortly after the peak of the January 2011, floods. Given that bull sharks prefer shallow water near tropical coastlines, they are the most likely to encounter humans. Great White Shark Lifespan: How Long Do Great White Sharks Live? [50] The size of a fully matured female bull shark to produce viable eggs for fertilization seems to be 175cm to 235cm. However, there are over 1000 species of shark that range in size from the dwarf lantern shark, which is smaller than a human hand to enormous whale shark so named for its whale-like proportions. [49] After gestating for 12 months, a bull shark may give birth to 1 to 13 live young. Adult bull sharks have few natural predators. [46][47], Sharks are opportunistic feeders,[45] and the bull shark is no exception to this, as it is part of the Carcharhinus family of sharks. The inshore nursery grounds are particularly at risk. As a result, the bull shark is listed as the shark most likely to injure people. It commonly enters estuaries, bays, harbors, lagoons, and river mouths. The meat is either used for fish meal or sold in local markets for human consumption. Bull sharks have large, round, stocky bodies. Though the bull shark is not a targeted species in most commercial fisheries, it is regularly captured on bottom longline gear. [34] Reproduction is one of the reasons why adult bull sharks travel into the riverit is thought to be a physiological strategy to improve juvenile survival and a way to increase overall fitness of bull sharks. It is important that every Male bull sharks weight around 200 pounds while female bull sharks can reach up to 290 pounds. The bull shark was first described by Valenciennes in Muller & Henle (1839) as Carcharias (Prionodon) leucas, and later changed to the currently valid name Carcharhinus leucas. Bull sharks appear sluggish as they cruise slowly along the bottom, but are capable of quick bursts that allow them to capture smaller, agile prey. Distinctive Features Size at birth is 56-81 cm (~2-3 ft) and size at maturity is 157-226 cm (~5-7 ft) for males and 180-230 cm (~6-7.5 ft) for females (Simpfendorfer and Burgess 2009). Two full-grown American Pit Bull Terrier dogs. They are found cruising the shallow, warm waters of all the worlds oceans. On average, adult males are about 7 feet (2.1 m) long weighing 200 pounds (90 kg). Bull sharks occur in tropical to subtropical coastal waters, worldwide. [31] The golf course has capitalized on the novelty and now hosts a monthly tournament called the "Shark Lake Challenge". Winter is coming. [39] Recent work also shows that the differences in density of fresh water to that of marine waters result in significantly greater negative buoyancies in sharks occupying fresh water, resulting in increasing costs of living in fresh water. Adult male great white sharks are 11 to 13 feet long whereas females can be from 15 to 20 feet long. It is found to a depth of 150m (490ft), but does not usually swim deeper than 30m (98ft). This is a tricky question. The average weight of an American Bully is around 66 88 lb. The bite force of an animal relates to the strength and pressure of its bite. 2009. They are gray on top and white below, and the fins have dark tips, particularly on young bull sharks. The bull shark is able to discriminate between colors of mesh netting that is present underwater. Check out this chart comparing some of the most significant differences between these two sharks. The average weight of a great white shark is 5,000 pounds (2,268 kg). In younger individuals the fins have dark tips which fade to a more diffuse dusky color as they grow. Dentition Still greater numbers are in the canals of the Gold Coast, Queensland. Unlike the river sharks of the genus Glyphis, bull sharks are not true freshwater sharks, despite their ability to survive in freshwater habitats. Initially, scientists thought the sharks in Lake Nicaragua belonged to an endemic species, the Lake Nicaragua shark (Carcharhinus nicaraguensis). They have been recorded to move at over 11 mph (19 km/h) over short distances. It was found that bull sharks tended to avoid mesh netting of bright colors rather than colors that blended in with the water. [34] The majority of the newborn or very young bull sharks were found in the freshwater area, whereas the much older bull sharks were found to be in the saltwater areas, as they had developed a much better tolerance for the salinity. The bull shark's caudal fin is longer and lower than that of the larger sharks, and it has a small snout, and lacks an interdorsal ridge. Growth rates have been calculated by Thorson and Lacy (1982) using tag recapture information in Lake Nicaragua. Weight. The easiest way to tell Bulls and Great Whites apart is by their sheer size. Bull Sharks generally dont grow longer than 8 feet, and max out around the 11-12 mark. Great Whites are much, much bigger. What shark has killed the most humans? Great white sharks are much larger than bull sharks. The Bull Shark belonged to the family Carcharhinidae, mainly distributed in Ocean. Carcharhinus leucas. Particle physics is on the case. Further research is necessary to better characterize its biological, ecological, and fisheries significance (Simpfendorfer and Burgess 2009). 90kg - 230kg (200lbs - 500lbs) Lifespan. Which shark has a reputation for being more dangerous? Bright yellow mesh netting was found to be easily avoided when it was placed in the path of the bull shark. Anterior teeth are erect and nearly symmetrical, while posterior teeth become more oblique in shape. It is considered by many to be the most dangerous shark in the world. Bull sharks have attacked swimmers around the Sydney Harbour inlets. Bull sharks are aggressive, common, and usually live near high-population areas like tropical shorelines. A great white sharks upper body is dark gray, blue, or even black. Great white sharks can weigh 5,000 pounds or more when fully grown. The movement was found to be directly related to the bull shark conserving energy for itself. When we hear about sharks, we tend to envision the great white. [10], Bull sharks are large and stout, with females being larger than males. 2005). Food Habits The second dorsal fin is smaller than the first. They were trapped following a flood of the Logan and Albert Rivers in 1996. [2][43][44] Bull sharks have been known to use the bump-and-bite technique to attack their prey. Bull sharks can grow to a total length of about 340 cm. But the weight of a shark does have an effect on its total bite force. [20] Bull sharks are one of the three shark species (along with the tiger shark and great white shark) most likely to bite humans.[5]. [34] These fish also are euryhaline fish, able to adapt to a wide range of salinities. This page was last edited on 11 December 2022, at 16:38. The maximum reported length of the bull shark is 400 cm (~13 ft) (Compagno et al. [citation needed] It can live in water with a high salt content as in St. Lucia Estuary in South Africa. > Check the status of the bull shark at the IUCN website. Their diet can also include turtles, birds, dolphins, terrestrial mammals, crustaceans, and echinoderms. In a research experiment, the bull sharks were found to be at the mouth of an estuary for the majority of the time. Have some feedback for us? Evolutionary assumptions can be made to help explain this sort of evolutionary disconnect, one being that the bull shark encountered a population bottleneck that occurred during the last ice age. Because of these characteristics, many experts consider bull sharks to be the most dangerous sharks in the world. Dimensions: 247.6 x 157.4 x 7 mm (9.75 x 6.20 x 0.28 in), Dimensions: 165.9 x 76.2 x 8 mm (6.53 x 3.00 x 0.31 in), Dimensions: 162.9 x 76 x 7.9 mm (6.41 x 2.99 x 0.31 in), Dimensions: 162.9 x 76 x 9 mm (6.41 x 2.99 x 0.35 in). There are over 1000 species of sharks living throughout the world. 143 to 186 lbs. The shark is pending certification, but if it that weight is official, it would blow away Alabamas current record of 336 pounds, 8 ounces. Looking up from below, a sharks light underbelly helps it to blend in with the sunlight filtering through the surface of the water. Someone looking into the ocean from above would not be likely to see a shark with its dark upper body. Great white sharks are much larger than bull sharks. 124 to 147 lbs. The industry made famous in 'Tiger King' to be banned, A rare look at the worlds most expensive sheep. Froese, Rainer; Pauly, Daniel (eds.) Height Weight Normal: Overweight: Obese: 4' 10" 91 to 118 lbs. Mature females commonly have scratches from the mating process. Coastal lagoons, river mouths, and other low-salinity estuaries are common nursery habitats (Simpfendorfer and Burgess 2009). The International Game Fish Association world record all-tackle bull shark weighed 617 pounds. However, they frequent the turbid waters of estuaries and bays, and often attack people inadvertently or out of curiosity. All rights reserved. They estimated that in the first two years, the growth rate is about 16-18cm per year. One study has found that their average lengths have declined significantly over the past few decades. The bull shark is not currently legally protected in any part of its range. Size of Bull Shark. Bull sharks and great white sharks are two of the most interesting. In terms of size, great white sharks are longer than bull sharks. Great white sharks are most likely to be seen swimming out in the open ocean. However, However, their behavior and social interactions set them apart. How Much Do Sharks Weight? Snout is much shorter than width of mouth and bluntly rounded. As an Amazon Associate I earn from qualifying purchases. Maximum speed. This will be around 10-13 inches tall for a male English Bulldog and approximately 9-11 inches tall for a female English Bulldog. The combined age at length data for both sexes were applied to a von Bertalanffy growth model producing parameter estimates of L = 285 cm TL, K = .076, t0 = 3.0 yr.

Great white sharks are most likely to injure people in deeper or colder waters, which is why they are more of a threat to surfers. Its gauged in PSI, or pounds per square inch. The worlds oldest map of the night sky was amazingly accurate. Reproduction Bull sharks caught in freshwater have subsequently been shown to have lower liver densities than sharks living in marine waters. Table 2. The bull shark does not rear its young; the young bull sharks are born into flat, protected areas. [11] Adult female bull sharks average 2.4m (8ft) long and typically weigh 130kg (290lb), whereas the slightly smaller adult male averages 2.25m (7ft) and 95kg (209lb). [26] Bull sharks have occasionally gone as far upstream in the Mississippi River as Alton, Illinois,[27] and up the Ohio River as far as Manchester, Ohio. The developing pups (one to thirteen per litter) are nourished internally via a yolk-sac placenta. While male bull sharks are usually around seven feet long, a female can measure up to 11 feet. The IUCN is a global union of states, governmental agencies, and non-governmental organizations in a partnership that assesses the conservation status of species. The top swimming speed of a bull shark is 25 miles per hour (40 km/h). For comparison, the fastest swimmer on record, with 28 Olympic medals to his credit, is Michael Phelps. Even in a special outfit that allowed him to beat his Olympic records, he was only able to swim at 8.8 MPH (14.16 km/h), far slower than a shark. They are known to travel far up rivers, and have been known to travel up the Mississippi River as far as Alton, Illinois,[3] about 1,100 kilometres (700mi) from the ocean, but few freshwater interactions with humans have been recorded. Make sure that your dog grows up in an environment that is healthy and is provided with the best possible nutrition. Both the great white and the bull shark are at the larger end of that spectrum. After capturing prey, great white sharks in a school may fight with one another for a bigger portion of the food. [42] Bull sharks tagged inside the lake have later been caught in the open ocean (and vice versa), with some taking as few as seven to 11 days to complete the journey. In addition, fish, sharks, stingray are also foods that it often preys.Their main predators are human, tiger sharks. Size, Age & Growth Normally, sharks eat in short bursts, and when food is scarce, sharks digest for a much longer period of time in order to avoid starvation. They are not bothered by brackish and freshwater, and even venture far inland via rivers and tributaries. From there, weights are smaller and change according with the species. Since the bull shark occurs in several underdeveloped regions of the world including Central America, Mexico, India, East and West Africa, the Middle East, Southeast Asia, and the South Pacific, bites often go unreported. [37] The gills of bull sharks are likely to be involved in the uptake of sodium and chloride from the surrounding fresh water,[38] whereas urea is produced in the liver as required with changes in environmental salinity. There are more than 50 different species! Coad, B. W. (2015). 4' 11" 94 to 123 lbs. Bull sharks prefer shallow water and can tolerate fresh water. 148 to 193 lbs. Generally, a bull sharks bite force is stronger than a great white sharks bite. However, bull sharks in fresh water possess several organs with which to maintain appropriate salt and water balance; these are the rectal gland, kidneys, liver, and gills. It is known for its aggressive nature, and presence mainly in warm, shallow brackish and freshwater systems including estuaries and lower reaches of rivers. These large stout sharks are found in both salt and fresh water. The dark and light coloration helps both sharks to camouflage themselves in the ocean waters. 179 attacks came out of the blue while 13 have been provoked by humans. Montauk Marine Basin-- Estimated Shark Weights Estimated Shark Weights The following is a chart that will give you a good idea how big the fish is if you are luckly enough to Age of maturation for female bull sharks is estimated to be 18 years (6-7.5 feet (180-230 cm) total length, TL) and 14-15 years (5.1-7.41 feet (157-226 cm) TL) for males (Branstetter and Stiles 1987). While they sometimes share the same waters while hunting, they dont interact as a rule. Please be respectful of copyright.

Many of these bite incidents were attributed to the Ganges shark, Glyphis gangeticus, a critically endangered river shark species, although the sand tiger shark was also blamed during the 1960s and 1970s. Young bull sharks, however, can fall prey to tiger sharks (Galeocerdo cuvier), sandbar sharks (Carcharhinus plumbeus), and other Bull sharks. Who would win: bull shark or the great white? The snout of a great white shark is slender and streamlined. [citation needed]. Larger sharks, such as the tiger shark and great white shark, may attack them, but typically only target juveniles. [33] Other species that enter rivers include the stingrays (Dasyatidae, Potamotrygonidae and others) and sawfish (Pristidae). Is a bull shark bite stronger than a great white? London: Harper Collins Publishers Ltd. Simpfendorfer, C. & Burgess, G.H. Females may be over 11 feet long and weigh about 500 pounds. While a bull shark is a large predator that grows up to 11 feet (3.5 m) or more, the bullhead shark is much smaller, usually getting no longer than about 5 feet (1.5 m). Parasites of the bull shark include the copepods Pandarus sinuatus and Perissopus dentatus. In the western Atlantic, bull sharks migrate north along the coast of the U.S. during summer, swimming as far north as Massachusetts, and then return to tropical climates when the coastal waters cool (Simpfendorfer and Burgess 2009). In 1961, following specimen comparisons, taxonomists synonymized them. The bull shark can be up to 81 cm (2 ft 8 in) in length at birth. 25 mph. Their common name comes from their short blunt snout which is They have been reported 3700 km (2220 mi) up the Amazon River in Peru, and over 3000 km (1800 mi) up the Mississippi River, in Illinois. In the Gulf of Mexico mating occurs during summer months, and the pups are born the following April-June. Also, they live in different areas of the ocean. The bull shark is considered the likely culprit for the infamous series of five attacks that occurred in New Jersey in 1916 that resulted in four fatalities over a 12 day period. Tiger sharks head the list as most aggressive toward humans. [45] As part of their survival mechanism, bull sharks will regurgitate the food in their stomachs in order to escape from a predator.
