Phyllidiopsis loricata (Bergh, 1873)
|Maximum size: 19 mm.
has a white body, typically with 8-10 large black spots encircling the
mid-dorsal area and fewer smaller spots scattered randomly among them.
The notum is opaque-white becoming translucent-white around the mantle
margin. Upon close examination, iridescent striae can be seen in the
center of the notum representing embedded spicules radiating from the
midline. Many tiny tubercles cover the notum and line up
medially in several low, longitudinal ridges giving the animal a rough
appearance. The fused oral tentacles are very large for the animal’s
size. It can be distinguished from Phyllidia
scottjohnsoni by the lack of black spots mid-dorsally and
presence of fused oral tentacles.

Observations and comments:
1: Keoki Stender also illustrates it on white sponges on his site and suggests that it may feed on Leiodermatium sp. although the identity of the sponges in the photos is somewhat uncertain...
