The Life of Sharks
There are 375 species of sharks.Stingrays are relatives of the sharks.The horn shark lays eggs in a spiral shape to blend in with the rocks to protect it from predators.Once the shark pups are born they are on their own.Some sharks use camouflage to hunt but also to hide from predators.The cookie cutter shark is known for leaving cookie like bite marks on their prey. Sharks can't really bite people with chain mail suits even if they have fish in their sleeve because their teeth will get stuck in the chain.
