Some hermit crabs walk around with Sea Anemones on their shells. This is an advantage to both animals. The Sea Anemone provides protection with its stinging tentacles for the crab from predators. The crab is a messy eater, and any scraps from a meal will be left on the ocean floor and the Anemone quickly gobbles it up on its way by. Eel grass is a long leaf that stays with other leaves that sway in the current.
Small fish find it quite livable in the eel grass, for it provides food, protection and shelter.
Plankton can live in any ocean water. Plankton is tiny plants and animals that can only be seen with a microscope. Plankton is also a good source of food for small fish. Well now we must say goodbye to the tide pools until the next time. I think everyone will agree with me that home is where the tide pool is.
