Growth and population structure in two species of bivalves (Nuculanidae) from the deep sea
ABSTRACT: Numerous specimens of Nuculana pernula and Yoldia thraciaeformis (Bivalvia: Nuculanidae) were collected from depths of 895 to 1500 m in the Northwest Atlantic Ocean off Newfoundland. Sizes attained by both species approach or exceed previously recorded maximum lengths. The populations are...
