Codas

While nonidentity codas are commonly used in multiple different clans, some codas express clan identity, and denote different patterns of travel, foraging, and socializing or avoidance among clans. In particular, whales will not group with whales of another clan even though they share the same geographical area. Statistically, as the clans' ranges become more overlapped, the distinction in clan identity coda usage becomes more pronounced. Distinctive codas identify seven clans described among the approximately 150,000 female sperm whales in the Pacific Ocean, and there are another four clans in the Atlantic. As "arbitrary traits that function as reliable indicators of cultural group membership", clan identity codas act as symbolic markers that modulate interactions between individuals.
