Sperm whale codas may encode individuality as well as clan identity.
Sperm whales produce codas for communication that can be grouped into different types according to their temporal patterns. Codas have led researchers to propose that sperm whales belong to distinct cultural clans, but it is presently unclear if they also convey individual information. Coda clicks comprise a series of pulses and the delay between pulses is a function of organ size, and therefor...
متن کاملIndividual, unit and vocal clan level identity cues in sperm whale codas.
The 'social complexity hypothesis' suggests that complex social structure is a driver of diversity in animal communication systems.

We examined variation in coda repertoires a...
متن کاملTime patterns of sperm whale codas recorded in the Mediterranean Sea 1985-1996.

متن کاملSperm whale sound production
largest, yet most elusive, creatures inhabiting deep ocean waters. Adult sperm whales undertake long, deep dives (Watkins et al., 1993) into the darkness and high pressure of the mesoand bathypelagic depths. They do this to locate and catch approximately 1000 kg (Lockyer, 1981) of medium-sized squid and fish (Clarke et al., 1993) each day. The most prominent feature of the sperm whale physique ...
