Lomanotus vermiformis

''Lomanotus vermiformis'' is a species of sea slug, a marine gastropod mollusk in the family Lomanotidae.
Lomanotus vermiforis Sea Slug Lomanotus vermiformis, as its name suggests, is particular elongate. It is always found on its food, the aglaopheniid hydroid Lytocarpus philippinus, on which it is particularly well camouflaged. It clings tightly to the hydroid with its narrow grooved foot and a very sticky mucous secretion. It thrashes wildly with lateral body flexions when removed from the hydroid. It seldom grows larger than 25mm. Cebu,Geotagged,Lomanotus vermiformis,Malapascua,Nudibranch,Philippines,Sea Slug,Spring
