Culcita Schmideliana Video Stock Footage
Culcita schmideliana is a roughly pentagonal starfish with a leathery surface and an inflated appearance. It is subglobose in shape with a very convex aboral (upper) surface and flat base. The aboral surface is scattered with small conical spines and the oral (under) surface has small granulations and is clad in large conical tubercles, those nearest the ambulacral grooves and the margin being ovate in cross section and the largest. This starfish varies in color but often has a greyish background with small pink patches mostly adjacent to black tubercles. The madreporite is usually an orangeish color. This starfish often has several commensal animals in its body cavity or on its surface. A carapid fish is usually to be found living in its stomach and sometimes the polychaete worm Gastrolepidia clavigera crawls over its surface. There is also often a tiny commensal shrimp Periclimenes soror hiding almost invisibly on its aboral surface.
