Blue Sharks

Known as the ballerinas of the sea, blue sharks are long, elegant, and slow moving, but don't let that fool you! While blue sharks are not as aggressive as some other types of sharks, their serrated teeth, long pectoral fins, and teamwork mentality make them just as vicious as their larger relatives. From their ability to sense electromagnetic fields to their excellent vision, blue sharks are fierce predators. There are more blue sharks in the world than any other type of shark, but much of their lives is still a mystery, as they spend most of their time in the vast, open ocean, far from humans.
