The next time you think Orcas are satisfied with living in captivity:
Orcas have evolved complex culture: a suite of behaviors animals learn from one another. They communicate with distinctive calls and whistles. They can live 60 years or more, and they stay in tightknit matrilineal groups led by older females that model specific behaviors to younger animals. Scientists have found increasing evidence that culture shapes what and how orcas eat, what they do for fun, even their choice of mates. Culture, says Hal Whitehead of Dalhousie University in Halifax, Nova Scotia, “may be very important to them.”
Some of the first evidence of cultural differences among orcas came from studies of vocalizations in whales that frequent the coastal waters of British Columbia and Washington State. Such “residents” belong to four clans, each with multiple groups. While the clans live close together—their ranges even overlap—their vocalizations are as different as Greek and Russian. And smaller groups called pods have dialects akin to a Southern drawl or a clipped New England accent.
Reblog for favorite animal, and for a very under-appreciated thesis explaining huge cultural.differences in animal groups. If human culture varies from Oregon to Georgia to Argentina to South Africa, how is it unreasonable to.expect the same of animal groups?.it’s not;.orcas have a crazy complex social structure.
