Justification:
|
This species is widely distributed in the world’s oceans, particularly in warm temperate and tropical areas. The animals are difficult to observe and have not been studied directly in the wild. Much of what is known about it comes from strandings. A limited amount of hunting has taken place in at least Japan, the Lesser Antilles, Sri Lanka, and Indonesia, but this species is not a major target of exploitation. Mortality in fishing gear, especially gillnets, is likely a more serious problem. However, the data on mortality levels and whale abundance are far from sufficient for a proper assessment. Ingestion of plastic debris may contribute to morbidity and mortality (J. Mead, cited in Laist et al. 1999). (Account based on Reeves et al. 2003, p. 50).
