Phylum coelenterata characteristics is they have a single opening into the body which acts as both the mouth and anus which functions in taking food and expelling wastes.
One of the most important distinguishing characteristics of the phylum are the Nematocysts. Nematocysts, and their enclosing Cnidocysts come in about 24 different forms, the differences play a functional role in the classification of the phylum. A Cnidocyst is a cell that secretes a nematocyst within it.his temperature range is 23 to 29 degrees C, or 73 to 84 degrees F. There are fears that global warming could have a disastrously destructive effect on the world's remaining coral reefs. The Cnidaria come in two basic forms, a 'Polyp' form typified by the Sea Anemones and a 'Medusa' form typified by Jellyfish.
