The coral polyp will pull into the cup to take shelter. collectively the corals are the stratum for coral reefs. other than the more common stony corals are some “soft corals” that take on more of a mound shape without the hard calcium carbonate skeletons. corals have a symbiotic relationship with an algae called zooxanthellae. zooxanthella. October 4, 2023. cnidarians are a diverse group of aquatic animals that includes jellyfish, corals, sea anemones, and hydras. they are characterized by their radial symmetry, diploblastic body plan, gastrovascular cavity, and nematocysts. cnidarians can be found in all marine habitats, from the shallowest coral reefs to the deepest oceans. Describe the identifying features of the major cnidarian classes. phylum cnidaria includes animals that exhibit radial or biradial symmetry and are diploblastic, meaning that they develop from two embryonic layers, ectoderm and endoderm. nearly all (about 99 percent) cnidarians are marine species. whereas the defining cell type for the sponges.

Figure 28.2.1 28.2. 1: animals from the phylum cnidaria have stinging cells called cnidocytes. cnidocytes contain large organelles called (a) nematocysts that store a coiled thread and barb. when hairlike projections on the cell surface are touched, (b) the thread, barb, and a toxin are fired from the organelle.
