A Warty Sea Slug
The Warty Dendrodoridid, Dendrodoris warta Marcus & Gallagher, 1976, is a large local nudibranch (a shell-less gastropod) that may reach 120 mm (about 4.7 inches). The species is found in shallow water along the western coast of Florida, and the coast of Georgia. Warty Dendrodoridids have prominent knob-like tubercles scattered over its "back". The species is known to feed on encrusting sponges. The photo was taken by Amy Tripp, on Kice Island, Florida.
