(‘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 άνθος (ánthos; “flower”) and ζώα (zóa; “animals”), hence ανθόζωα (anthozoa) = “flower animals”, a reference to the floral appearance of their perennial polyp stage)
