#acalepha

• Acalepha — An archaic or scientific zoological term used to designate large marine jellyfish or, broadly, organisms belonging to the class Scyphozoa (phylum Cnidaria). These gelatinous, skeletonless organisms are characterized by their umbrella- or bell-shaped bodies and the presence of stinging cells (cnidocytes) on their tentacles, used for self-defense and paralyzing prey.
