Did you know that there are more than 370 species of sharks? Here is My shark report about the Port Jackson Shark. Its physical features are that it is about 5 ½ feet long. It is light brown and has a pig-like snout. This shark lives in the shallow waters near Australia where it swims slowly. It eats oysters, snails, crabs, and some fish. This shark can eat and breathe at the same time. What an unusual shark!
