Comments: Has been successfully maintained in several marine aquaria. Sometimes taken for human food and oil in mass shore drives in Japan and in small cetacean fisheries in Taiwan and the Caribbean (Leatherwood and Reeves 1983, Stacy et al. 1994). Sometimes regarded as pest by fishermen who perceive these whales as a competitor for fishes. Sometimes takes fishes hooked on fishing lines; sometimes causes significant impact on tuna long-line fishery in the tropical Pacific (IUCN 1991).
