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. [52] The speculation that bull sharks may have been responsible is based on two fatal bites occurring in brackish and fresh water. Unlike the river sharks of the genus Glyphis, bull sharks are not true freshwater sharks, despite their ability to survive in freshwater habitats. Bright yellow mesh netting was found to be easily avoided when it was placed in the path of the bull shark. [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 bull shark name derives from its stout appearance and reputation for aggressive behavior. A 20-foot great white shark is likely to have a stronger bite force than an eight-foot bull shark.

First dorsal fin originates over or slightly behind pectoral insertion, 3. Predators Winter is coming. Bull sharks in freshwater environments decrease the salt-excretory activity of the rectal gland, thereby conserving sodium and chloride. 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).

[33] Other species that enter rivers include the stingrays (Dasyatidae, Potamotrygonidae and others) and sawfish (Pristidae). Elasmobranchs' ability to enter fresh water is limited because their blood is normally at least as salty (in terms of osmotic strength) as seawater through the accumulation of urea and trimethylamine oxide, but bull sharks living in fresh water show a significantly reduced concentration of urea within their blood. Bull sharks prefer shallow water and can tolerate fresh water. Is a bull shark bite stronger than a great white? The inshore nursery grounds are particularly at risk. The bull shark can be up to 81 cm (2.66 ft) in length at birth.

Juvenile bull sharks enter low salinity estuaries and lagoons as readily as adults do and use these shallow areas as nursery grounds. Fast, agile predators, they will eat almost anything they see, including fish, dolphins, and even other sharks. The genus name Carcharhinus is derived from the Greek karcharos = sharpen and rhinos = nose. This has been a topic of controversy for many years, and there is evidence that points to the involvement of both the bull shark and the white shark.

[48], Bull sharks mate during late summer and early autumn,[9] often in bays and estuaries. The driving factor for a bull shark to be in fresh or salt water, however, is its age; as the bull shark ages, its tolerance for very low or high salinity increases.

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. 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). The average male great white is 11 to 13 feet long (3.4 to 3.9 meters). 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). Mating and birthing occurs year-round in the warmest parts of the range. Bull sharks are pale to dark gray above, fading to a pale cream color on their underside.

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. Among the most likely sharks to attack humans, bull sharks favor shallow coastal watersthe same places humans prefer to swim. Great whites tend to be social animals who swim together in groups. The maximum reported length of the bull shark is 400 cm (~13 ft) (Compagno et al. The courting routine between bull sharks has not been observed in detail as of yet. osmolarity) of a bull shark in fresh water is still much higher than that of the external environment. The fins are used in Asia for shark fin soup while the skin is frequently used for leather (Simfendorder and Burgess 2009). Bull sharks are fished widely for their meat, hides, and oils, and their numbers are likely shrinking. Larger sharks, such as the tiger shark and great white shark, may attack them, but typically only target juveniles. Maximum speed. There are more than 50 different species! [51], Since bull sharks often dwell in very shallow waters, are found in many types of habitats, are territorial by nature, and have no tolerance for provocation, they may be more dangerous to humans than any other species of shark.

[8], Some of the bull shark's closest living relatives do not have the capabilities of osmoregulation. (Branstetter and Burgess 1997). Further research is necessary to better characterize its biological, ecological, and fisheries significance (Simpfendorfer and Burgess 2009). [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. 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 Heres why thats good.

Bull sharks caught in freshwater have subsequently been shown to have lower liver densities than sharks living in marine waters. The bull shark is not currently legally protected in any part of its range. The bull shark is a large active predator. Check out this chart comparing some of the most significant differences between these two sharks. It is more often targeted in small artisanal fisheries because of its abundance in nearshore environments. [citation needed], After Hurricane Katrina, many bull sharks were sighted in Lake Pontchartrain. However, the great white shark is the faster of the two. While a maximum size of 3.5m (11ft) is commonly reported, a single record exists of a female specimen of exactly 4.0m (13ft). The most obvious difference is size. [2][43][44] Bull sharks have been known to use the bump-and-bite technique to attack their prey. We may be getting closer. Bull sharks are aggressive, common, and usually live near high-population areas like tropical shorelines. 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. A full grown bull shark can be around 10 to 11 meters in length. Tiger sharks head the list as most aggressive toward humans.

While male bull sharks are usually around seven feet long, a female can measure up to 11 feet. This is a tricky question. Most of the time, a shark bites a human because it mistakes the persons arm or leg for a fish or other prey. 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.
