Dilemma is a genus of marine bivalves of the family Poromyidae.[1] The genus is remarkable for encompassing predators of isopods and ostracods, unusual for sessile molluscs.[2] One species is known from the western Atlantic Ocean (Straits of Florida) and three from across the Pacific. Specimens have been found at depths between 229–961 m (751–3,153 ft).[2][3] The name of the genus refers to the dilemma that the author of the new genus faced while diagnosing it.[2]
