Cnidarians

The phylum cnidaria such as sea anemones and their relatives are plant like in form during at least part of their life cycle. In some cases cnidarians are even colored green (such as green sea anemones) like typical plants. Unlike other plant like marine animals, the cnidaria are usually not filter feeders but carnivores. The cnidarians feed mainly on sizable animals that wonder too close to them. These sit and wait cnidaria predators use tentacles loaded with stinging cells to capture prey.
