Food habits of Atlantic white-sided dolphins (Lagenorhynchus acutus) off the coast of New England
Although the Atlantic white-sided dolphin (Lagenorhynchus acutus) is one of the most common dolphins off New England, little has been documented about its diet in the western North Atlantic Ocean. Current federal protection of marine mammals limits the supply of animals for investigation to those in...
