The Bull Shark is one of the world’s most unique sharks. The reason why it is one of the most unique sharks is the shark’s habitat, it has an ability to swim and live in freshwater areas such as rivers. Not every shark has the ability to live in freshwater areas, the Bull Shark has a few adaptations that make it possible for it to live in fresh water. Some adaptations are they have the ability to have blood that has less salt then the water that the shark is living in, bull sharks and other freshwater marine animals can have less salt in their blood by constantly producing urine that has high amounts of salt.  Bull Sharks usually live around North and South America.

 

Second the general description. Male Bull Sharks average 2.12m[7ft] weighing 200lband female sharks average 4m [13.1ft] weighing 700 lb. Bull Sharks have a grayish white color on top and white on bottom Bull Sharks reproduces during summer. The main characteristics’ of the shark is medium size ,flat snout, moves slowly but will spring into action at very high speeds when they are in a feeding frenzy or when they become aggressive. Although the Bull Shark has many adaptations they still have predators. The main predator that bull sharks have is freshwater crocodile, saltwater crocodiles, and other sharks but the biggest threat to the shark is humans.

 

The Bull Shark catches it’s prey by moving very slowly through the water and suddenly ambushing its prey at very high speeds , this type of shark usually prey on rays,dolphins,turtles,and mollusks . Bull Sharks are solitary hunters so they usually hunt alone, they usually do not fear other animals in the water near them. An interesting Fact that I found out about the Bull Shark is how they can swim very low water level places like rivers and lakes and deltas. While I was researching this animal I learned several facts. Bull Sharks can swim in fresh water using osmoregulation they are also the worlds top 3 most dangerous sharks to humans each year Bull Sharks and other sharks claim lives around the world .
