Jellyfish Corals Hydroids - Cnidaria
All Cnidarians are acoelomates (no body cavity); they have stinging cells called nitoblasts. These nitoblasts have hair triggers with a powerful neurotoxin. Cnidarians have both sexual and asexual reproduction cycles.
The polyp cycle can reproduce by budding off an exact clone of itself (but smaller), this is asexual reproduction; they can also produce a cloned larva asexually.
Cnidarians include the following:
1) Class: Anthozoa (CORALS, SEA ANEMONES)
2) Class: Hydrozoa (HYDROIDS, SIPHONOPHORES--Portugese Man-of-War)
3) Class: Schyphozoa (JELLYFISH)
