Cnidarians have jelly-like bodies with radial symmetry. They have very simple bodies with an opening at one end.

This opening acts as a mouth and an anus. They have soft tentacles to catch their prey.

All cnidarians are aquatic and most live in the sea. Sea anemones, corals and jellyfish are cnidarians.
