Bioacústica de baleias cachalotes (Physeter macrocephalus Linnaeus, 1758) com ênfase no oceano Atlântico Sul ocidental
Sperm whales live in multilevel societies in which the fundamental social level is the nearly-permanent social units of females and immature. The largest level is the clan constituted by social units that share a common coda repertoire. This work described the vocal repertoire of sperm whales from w...

Sperm whales live in multilevel societies in which the fundamental social level is the nearly-permanent social units of females and immature.
