Abstract
Cnidaria (Gr.,
cnidae
, nettle) is a phylum of mostly marine Metazoa distinguished by cnidocysts, subcellular encapsulated tubules capable of everting and, in some cases, discharging venom. Sexual reproduction results in solid planula embryos that develop into columnar polyps. Asexual reproduction results in clones of polyps, polypoidal colonies or disk‐shaped to bell‐shaped sexual medusas (jellyfish).
