Ancula pacifica is a species of sea slugs, a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae.
Distribution
This species was first described from Monterey Bay, California .
Description
This goniodorid nudibranch is translucent white in color with orange lines on the body. There is a mid dorsal line and lines along the pallial margin, which may be continuous or interrupted. The pre-rhinophoral papillae and gills are tipped with orange and there is a line of orange pigment along the ridge of the tail. There are 4-14 club-shaped extra-branchial papillae which are translucent white with orange or yellow tips. Small papillae with orange tips typically occur between larger papillae with pale yellow tips.[2] Individuals without the lines on the body occur in some populations. Although currently considered to be a synonym of the European species Ancula gibbosa there are significant differences in color and shape of the extra-branchial papillae and this is probably a distinct species.
Ecology
Ancula pacifica probably feeds on Entoprocta which often grow on hydroids, bryozoa and other living substrata.
