Ophelina acuminata

Ophelina acuminata is a species of marine annelids, found in the sublittoral mud and sand bottom.

Morphology[edit]

Body slender and 25–60 mm long, with 50 chaetae bearing segments. Colour yellowish or pearly grey with bright red gills, and all segments finely multi-annulated. The prostomium is conical, ending in a median progress with a slightly swollen tip and two big dorsolateral nuchal-crevasses. Except first, and two to three last segments, all chaetigers has long cirriform gills, and ventral cirri. Anus surmounded by a spoon shaped hood with a ventral opening, 20 fine annular rings and 14-20 long papillae along edge. On the ventral side of basis, two long cirrus, behind one unpaired longer cirri. .[1][2]

Ecology[edit]

Found marine, in the shallow sublittoral. Mostly on sand, but as well seen on mixed muddy bottoms, from 10 to 1200 m.[1][3] From Northern Atlantic, along the African west coast to South Africa, northern part of the Pacific, and in the Indian Ocean. Swims snake-like, or are digging in the upper part of the bottom. Substrate surface deposit feeder, reproduction unknown.[1]
