Notes on diet of sperm whales (Cetacea: Physeteroidea), stranded in Ceará State, Northeastern Brazil.
Between 1996 and 1999 four stomach contents of two sperm whale species were collected, three of Physeter macrocephalus and one of Kogia breviceps. A total of 2,779 squid beaks was obtained from the stomachs of the three P. macrocephalus specimens. Those mollusks were identified as belonging to at le...
