Description: As a member of Order Cheilostomatida, this species has box-shaped, calcified zooecia with opercula and often with spines. They also have several different forms of zooids including avicularia and vibracula. Embryos generally develop in brood chambers (ovicells).Phidolopora pacifica forms a unique, erect colony composed of a distinctive, lacy network of calcified material. The color is pale orange or salmon-orange when alive (as above).The primary aperture is symmetrical, sometimes with two distal spines and with the distal wall of the primary aperture beaded. There are avicularia on the frontal wall and large hooked avicularia on the dorsal side at the base of the fenestrations. All zooids open on the ventral side. The dorsal side of the colony is lined with kenozooids (membrane-coveres spaces without individual animals). The frontal walls have only a few small pores and few areolae.
How to Distinguish from Similar Species:Phidolopora labiata is also a valid species, but according to marinespecies.org what was formerly called P. labiata in the Pacific Ocean is now called Phidolopora pacifica.
Geographical Range: Pacific ocean, with subspecies names for forms apparently from Catalina California and Japan.
History: This form
of "chicken wire"-like fenestrated network structure in bryozoans is
to as "retroporid".
