Anthozoa \An`tho*zo"a\, n. pl. [NL., fr. Gr. 'a`nqos flower + ? animal.] (Zo["o]l.) The class of the C[oe]lenterata which includes the corals and sea anemones. The three principal groups or orders are Acyonaria, Actinaria, and Madreporaria.
Anthozoa is a class within the phylum Cnidaria. Unlike other cnidarians, anthozoans do not have a medusa stage in their development. Instead, they release sperm and eggs that form a planula, which attaches to some substrate on which the cnidarian grows. Some anthozoans can also reproduce asexually through budding. More than 6,100 species have been described.
The name comes from the Greek words (; " flower") and (; "animals"), hence ανθόζωα (anthozoa) = "flower animals", a reference to the floral appearance of their perennial polyp stage.
