The Atlantic white-sided dolphin (Lagenorhynchus acutus) is named for its coloration. This species has a black dorsal region that fades to gray along its sides and a distinctive white coloration running along its ventral surface most of the length of its body. The Atlantic white sided dolphin belongs to the Family Delphinidae, the largest family of the Order Cetacea, which includes killer whales, pilot whales, and other dolphins.
The main predators the Atlantic white-sided dolphin faces include killer whales and sharks. This dolphin is rarely sighted in inshore regions, prefering areas further out along the continental shelf where water depths reach 40-270m.
