Cnidarians

A sea anemone with a captured crab, surrounded by other plant life. Caption: Even a large crab can be digested within a few hours.

Part of the "Branches on the Tree of Life" series. Begins with a series of observations on Hydra, including habitat, structure, feeding, nematocyst discharge, locomotion (by looping), and its sexual and asexual reproductive strategies. Obelia illustrates the two-stage life cycle found in many cnidarians. Examining the biology of jellyfish (class Scyphozoa), sea anemones, and corals (class Anthozoa) rounds out the overview of phylum Cnidaria.
