Dendrogaster (Crustacea: Ascothoracida) parasitic in Alaskan and eastern Canadian Leptasterias (Asteroidea)
The ascothoracid parasite Dendrogaster is reported from four boreal localities in the Western Hemisphere. Dendrogaster elegans Wagin infests the sea star Leptasterias polaris in Bristol Bay, Alaska, and in the Gulf of St. Lawrence; the eastern specimens have a shorter brood sac middle piece. A lecto...
