Did you know that there are more than 370 different species of sharks? Here is MY shark report about the Blue shark. Its physical features are counter shading with blue on the top of its body and white on the bottom. It has a sleek shape that makes it a fast swimmer. This shark lives in warm tropical oceans and is found in open waters. It eats squid and tiny fish. This shark can use its senses to grab its prey quickly. What a fast shark!
