Symbiosis in the Sea

The ocean is full of surprises and danger, so it’s a pretty good idea to team up with another sea creature, especially if it’s bigger and badder. When two different kinds of living things form a close partnership, it is called symbiosis (say sim-BEE-oh-sis).

Check out these ocean partners. Use the key to help you decide if it sounds like a good relationship.

A) both animals benefit

B) one animal benefits and the other doesn’t mind

C) one animal benefits but the other doesn't
