Squid are sea creatures that look a bit like a cross between an octopus and a fish. They have eight long arms and two tentacles that stick out of their head. They have a large round head with big eyes and a funny smiling mouth. They are usually a reddish-brown color and they use their tentacles to swim around. Squid can also squirt a stream of water out of their back so they can move very quickly in the ocean. They eat small fish, crustaceans, and other sea creatures.
