Scientifically known as Carcharhinus Leucas, the Bull Shark can be easily found in the oceans. Bull Shark is one of the 43 species of shark found in both seawater and fresh water. Known to be one of the best shark species, the Bull Shark looks generic, unlike the other sharks.
Bull Shark is one of the three sharks that are most likely to attack humans; the other two being the Great White Shark and the Tiger Shark. However, data suggests that less than 4.5% of deaths are by shark attacks globally. Due to its aggressive behavior, this shark has been tagged “The Pit Bull of the Sea”.
Bull Sharks have only 50% of the salt concentration in their blood, unlike the other sharks that have the same amount of salt concentration in their blood as the sea water that they swim in. This characteristic feature offers Bull Sharks an advantage in terms of switching from saltwater to freshwater. However, as a consequence, Bull Sharks produce 20 times more urine when swimming in the fresh water.
Bull Sharks get their name from their short, blunt snout, and pugnacious disposition and the tendency to head-butt their prey before attacking. The medium-sized sharks are quite aggressive, common and usually never live near high-population areas like the tropical shorelines. The brackish or freshwater does not bother a Bull Shark.
Bull Shark –
Habitat and Behavior
Found at depths of around 150 m (490 ft), and not meaning to swim any deeper than 30m (98 ft), the Bull Shark can survive even if the water is just two feet deep. Bull Sharks are one amongst the only few species that can be found in freshwaters such as lakes, rivers, and streams all around the world. The Bull Shark is commonly found worldwide in coastal areas of the warmer oceans; In the Atlantic, it is found from Massachusetts to southern Brazil, and from Morocco to Angola.
Most female Bull Sharks give birth in shallow waters in order to prevent their younger ones from getting eaten by the bigger sharks in deep waters. They are known to mate during late summer and early autumn, often in freshwater or in the brackish water of the river mouths. Bull Sharks gestate for 122 months, after which they give birth to around 1 to 13 younger ones. Bull Sharks reach their maturity after about 10 years of age and become completely mature once they are 15 or 20 years old. They mate via internal fertilization and give birth to well-developed younger ones. Bull sharks do not connect to their young through a placenta. During the gestation period, the embryos survive off of yolk sacs attached to each individual. The adults normally grow up to 3.5 meters (11 feet) long and weigh around 300 kilograms (660 pounds). Typically, the female Bull Sharks are larger than the males and tend to live longer as well. Most males live for about 13 years, while females live for about 17 years of age. The younger specimens are free from predators while they grow up in the river. The ability of a Bull Shark to survive in both, the fresh water and the salt water functions as another benefit. The Bull Sharks are mostly attacked by bigger sharks that are able to survive only in the salt water. This leaves minimal chances of a younger Bull Shark to be attacked or harmed by a bigger one. They enter the salt water once they have grown up entirely and are able to find their own mates.
Bull Sharks can be easily found cruising the shallow and warm waters of all the world’s oceans. Being fast and agile predators, they will eat almost anything they see, including fish, dolphins and even other sharks. Unlikely to what has been thought of them, Bull Sharks do not tend to attack humans, per se. However, they often attack people inadvertently or out of curiosity.

Bull Shark –
Conditions for Survival
The Bull Sharks are aggressive predators and eat a variety of prey. They are particularly known to eat several species of the bony fish, small sharks, some mammals (terrestrial and marine both), seabirds, and sometimes sea turtles, as well. The Bull Shark’s diet also consists of stingrays, dolphin, starfish, sea urchins, crustaceans, and even land mammals that come to drink at the water’s edge. Bull Sharks usually hunt in murky waters where it is harder for the prey to identify the shark coming. The fish usually uses the bump-and-bite technique to attack its prey. After the first initial contact, the Bull Shark continues to bite and tackle its prey until it is unable to flee. Commonly known to be a solitary hunter, Bull Shark, often teams up with fellow Bull Sharks to make hunting easier.
Sharks are known to eat in short bursts, and when the food is scarce, they digest for a much longer period of time in order to avoid starvation of its own. As a part of their survival mechanism, the Bull Sharks regurgitate the food in their stomach in order to escape from its predator. This acts as a distraction tactic, in case the predator moves to eat the regurgitated food to be used given an opportunity to escape.
Being opportunistic feeders, adult Bull Sharks do not have any natural predators. However, they seldom have the fear of being attacked by other animals; humans being its biggest threat. Larger sharks, such as the Tiger shark, and the great white shark may attack them. In rivers, Bull Sharks may get attacked by Crocodiles, as have been observed as falling prey to Saltwater crocodiles.

How to make the Catch?
Being one among the most significant fish species, the Bull Sharks are subject to a log of fishing pressure. To land your hands on to one of these, you must work under certain precautions.
It is advised to use the hooks that match the size of the bait, and line class your chosen tackle. To catch a Bull Shark, you must use chemically sharpened hooks, usually Mustad big red or similar in sizes as 3/0 to 6/0; for a light tackle, hooks of 3/0 are used while Mustad big gun hooks must be used when fishing in areas where the sharks are over 1.5m. Using the Nylon coated wire, and the live bait is also highly recommended. Using the low-frequency vibrations given off by the bait add on to attracting the fish. You may also use cut baits by soaking them in the tuna oil, giving an added scent to the sharks.
