Like other species of the genus Lagenorhynchus
, the Atlantic white-sided dolphin is a stocky animal with a short, thick snout. It is common in cold North Atlantic waters. Most of what we know about its natural history has been learned by studying the carcasses involved in mass strandings, which can involve a hundred or more animals. Studies of stranded cetaceans are an important way to learn about these animals, and these events are carefully documented. Between 1968 and 1993, 348 Atlantic white-sided dolphins were stranded along the New England coast. From them, biologists have estimated growth and reproductive patterns, and have documented some of the foods they eat, which include a variety of fish and squid.
