Order Pennatulacea  

Pennatulaceans are octocorals with a oozooid modified to form a rachis bearing all secondary polyps (autozooids and siphonozooids), a barren stalk, and a peduncle for anchoring the colony in soft substrate (with a few rare exceptions [Alderslade, pers. comm.]). When present, the sclerites of pennatulaceans are in the form of simple rods, needles, plates, or egg-like ovals.

The Pennatulacea   are poorly represented in the shallow SAB. Four species occur in this region but only two appear to be common.
