how does it reproduce?
Sexually and asexually
Cnidaria
Not all cnidarians reproduce sexually, with many species having complex life cycles of asexual polyp stages and sexual medusae. Some, however, omit either the polyp or the medusa stage.
what are the 5 main features of cnidarians Cells bound by inter-cell connections and carpet-like basement membranes; muscles; nervous systems; and some have sensory organs. what type of specimen is this? It is a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments anything notable about its skeletal system? In medusae the only supporting structure is the mesoglea. "Hydra" and most sea anemones close their mouths when they are not feeding, and the water in the digestive cavity then acts as a hydrostatic skeleton, rather like a water-filled balloon what does it feed on? Symbiotic algae

Cnidaria [SEP] Introduction
Many cnidarian species produce colonies that are single organisms composed of medusa-like or polyp-like zooids, or both (hence they are trimorphic). Cnidarians' activities are coordinated by a decentralized nerve net and simple receptors. Several free-swimming species of Cubozoa and Scyphozoa possess balance-sensing statocysts, and some have simple eyes. Not all cnidarians reproduce sexually, with many species having complex life cycles of asexual polyp stages and sexual medusae. Some, however, omit either the polyp or the medusa stage.
