Cnidarians

Cnidarians are a special type of sea animal. All cnidarians have little stinging cells. Jellyfish, corals and anemones are all cnidarians.

Corals look like plants, but are really animals. There are hard and soft corals. The hard ones live together to form reefs. Lots of animals live in the reefs.

Jellyfish are different because they can move around. Corals stay in one spot. Jellyfish are very pretty. They have a round, soft top with long arms called tentacles. Be careful! If they sting, they hurt!
