Cuthona fulgens
(MacFarland, 1966)

Family: Tergipedidae


Cape Arago, Oregon to Shell Bch, California (Behrens, 1991)


Locality: Cape Arago, Oregon, USA. Pacific Ocean: Intertidal, Length: 9 mm. August 1983. Rocky shore, low intertidal pool. Photographer: Jeff Goddard


Body, including rhinophores and oral tentacles, are translucent white with some opaque white speckling. The cerata have opaque white spots on the skin and the digestive gland duct ranges from yellow-brown to dark-brown. There is a light yellow brown band at the base of each ceras and another subterminally. Behrens (1991) describes these as bands on the ceras, but from the attached photo, the bands appear to be part of the digestive gland duct or contents. MacFarland's published description is not entirely clear on this point but his painting also looks as though the yellow brown is from the upper and basal regions of the digestive gland duct. Grows to about 8 mm.
