(...) The free-swinging bullae of odontocetes are very massive, their specific weight being twice that of the other skull bones. This feature led Yamada (1953) to his theory that the…

Toothed whales (Odontoceti, Cetacea) are the only aquatic mammals known to echolocate, and probably all of them are able to produce click sounds and to synthesize their echoes into a…
The site and physiologic mechanism(s) responsible for the generation of odontocete biosonar signals have eluded investigators for decades. To address these issues we subjected postmortem toothed whale heads to interrogation…
Structural modifications of the odontocete skull and nasal passages have shifted the position of the facial bones and associated soft anatomy to the dorsal aspect of the head. The facial…

Phocoena sinus (vaquita) is a small marine harbor porpoise endemic to the Gulf of California that is believed to be the most endangered cetacean in the world as reported by…
Toothed whales (crown Odontoceti) are unique among mammals in their ability to echolocate underwater, using specialized tissue structures. The melon, a structure composed of fat and connective tissue, is an…
This paper describes the sonar sounds from four captive Neophocaena, two males and two females, which were tape recorded and processed with regard to their behaviour in the time and…
The characteristics of echolocation signals used by a harbour porpoise (Phocoena phocoena) during a target detection experiment are described. A water-filled steel sphere (either 5.08 or 7.62 cm in diameter)…
A comparison of the acoustic waveforms of three different species, Phocoena phocoena, Phocoena sinus and Neophocaena phocaenoides of the sub-family Phocoeninae is made with the species Phocoenoides dalli of the…
