At school, I made a big poster about Bull Sharks or Zambi Sharks. It is hanging in the hall near the front entrance right now. I chose the Bull Shark because it is unlike most other sharks and has some cool weird features. The Bull Shark is able to swim in fresh water! It is able to do so because it has special traits that other sharks don't.
The Bull Shark is named so because it is large and stout and I think more so because of its behaviour and personality. It is aggressive, grumpy and has been responsible for most attacks. It is one of the four most dangerous sharks. It usually hunts alone and it is know to eat other sharks. It usually likes to eat fish, dolphin and sea turtles. It is able to swim in shallow waters and has been spotted in Kentucky and Ohio rivers! Sometimes, when we afraid of something, it helps to learn a lot about it and it helps our fear go away.
A Bull Shark has organs that help it balance the right amount of salt and water in its body. Its rectal gland helps it dump out extra salt from living in seawater. When a Bull Shark is in freshwater, its rectal gland dumps out less salt. It gets pretty technical to explain how this works, but I think the Bull Shark is cool because it is so adaptable to seawater and freshwater.
Although it is not on the endangered list, we still need to keep a watch on it so that it doesn't get added to the list. There is so much overfishing, pollution and shark finning. We need to raise awareness. The Bull Sharks are part of our ecosystem and they need protecting too.
