DESCRIPTION
Bull SharksTRANSCRIPT
These sharks are known for their
aggression. An average adult weighs
380 lbs! They tend to hunt in waters
where people often swim: along
tropical shorelines. Bull sharks live
throughout the world, in shallow, warm
ocean waters. They've been known to
swim up into freshwater rivers. Humans
are not part of a bull shark's normal
prey however, bull sharks will eat
almost anything. Their diet consists
mainly of fish. They also sometimes eat
dolphins and sea turtles. Bull sharks
even eat other sharks.
These animals are
not to messed with.
They are a lot closer
than you think.
When you go
swimming in
Galveston or fishing
in West Matagorda
Bay, be aware of the
dangers. They are
not common pets.

while arguably appropriate given the

A Bull Shark gets to the prey
before a woman can reel it in.
Houston Chronicle July 12,
2012
These animals are fierce
predators but can also be
prey to other animals in
the sea and humans!
Adaptations
The Bull Shark is a unique shark that can live in both
ocean and fresh water. They can adapt readily to fresh
water because they can adapt their process of
osmogregulation. The kidneys of bull sharks can be
gradually adjusted to suit the salinity of the water they
are in. When moved gradually into freshwater (perhaps
by migrating from the ocean, to an estuary, and then
upriver), bull sharks' kidney's remove less salt and more
urea from the bloodstream through urination, essentially
reversing the normal marine shark method of
osmoregulation. This adaptation allows bull sharks to live
entirely in estuaries or freshwater. This could be an
adaptation that the bull sharks developed over many
years to help survive and be able to reproduce.
Female Bull Sharks can have anywhere from 1-13 pups (babies) in one litter.
Even though the Great White shark is the most dangerous shark in the world, the Bull Shark is the most dangerous shark to humans.
In order to get away, bull sharks employ a special technique – they throw up! The predator gets distracted by the vomit and the bull shark gets a chance to escape.
Females are larger than males on average and can reach weight of 500 pounds and length of 5 feet.
When a Bull shark looses a tooth, it's replaced every single time unlike us that only grow back once.
