Did you know that there are more than 370 different species of sharks? Here is my shark report about the Sandtiger shark. Its physical features are its grayish brown skin with dark spots. He is very large with very sharp teeth that look like the prongs on a fork. This shark lives in the shallow waters, reefs, and coastlines often near the sea floor in the Atlantic and Pacific Oceans. It eats fish, squid, shellfish, and other sharks. This shark can swallow air and keep it in its stomach. He is the only shark that can do this. What a dangerous shark!
