Peachia is a genus of sea anemone in the family Haloclavidae. Members of this genus typically burrow into soft substrates. The only part of the animal that is normally visible is the oral disc and tentacles which lie flat on the sand in a star shape. The type species is Peachia cylindrica (Reid, 1848).Genus Peachia Marine Species Identification Portal. Retrieved 2011-10-08.
Characteristics Members of the genus Peachia have a rounded base called the "physa" with tiny perforations, a tall column called the "scapus" and a delicate upper region called the "capitulum". The "siphonoglyph", a ciliated groove, is elongated and partially separated from the tubular throat, the "actinopharynx". There is a lobed projection called a "conchula", unique to this genus, at the entrance to the siphonoglyph. There are twelve, flattened tentacles. Six of the pairs of mesenteries dividing the internal body cavity are perfect while the other four are imperfect, with powerful retractor muscles. There is no sphincter muscle. The larvae are parasitic on medusae.
