Bycatch in artisanal gill nets threatens the vaquita, Phocoena sinus, with extinction. In 2008 the Mexican government announced a conservation action plan for this porpoise, with three options for a…
Morphology of the odontocete melon and its implications for acoustic function
McKenna, Megan F.; Cranford, Ted W.; Berta, Annalisa; Pyenson, Nicholas D.
Marine Mammal Science (2011)
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…
Intermingling of dalli-type Dall’s porpoises into a wintering truei-type population off Japan: Implications from color patterns
Amano, Masao; Hayano, Azusa
Marine Mammal Sci (2007)
There are two major color morphs, truei and dalli types, of the Dall's porpoise and the latter includes two minor morphs. A small number of dalli types are found among…
Co-variation in the probabilities of sighting harbor porpoises and bottlenose dolphins
Thompson, Paul; White, Sam; Dickson, Ellie
Marine Mammal Sci (2004)
(...) In this study we used data collected from commercial dolphin-watching trips to determine whether there was any relationship between the probabilities of sighting bottlenose dolphins and harbor porpoises. Surveys…
