Bull Shark

One of the top three most deadly shark species is the bull shark, which frequently attacks people who enter its habitat. It forages for fish, dolphins, and snakes in the murky river waters where it makes its home. People can't see it because it swims in murky, shallow water, and if they get too close, the shark will attack. Because the shark drags its victims into the water and causes them to drown or lose too much blood, the bite of the shark can be lethal. The species can reach a maximum length of 7 feet, although on average, females of the species grow to be 7.8 feet long and weigh 285 pounds.

The male of the species weighs around 209 pounds and is smaller than the female. One of the shark species that can thrive in both freshwater and saltwater is this one. The bull shark has half the salt content of the water around it, while other shark species have the same salt concentration in their blood as compared to the water around them, which allows them to move between saltwater and freshwater and vice versa. The bull shark can survive in water as shallow as 2 feet, which is why they frequently come into touch with people. Also, female bull sharks prefer to give birth in shallow water because they will prevent their young from getting eaten by the bigger sharks.
