Burmeister's porpoise (Phocoena spinipinnis) is a species of porpoise endemic to the coast of South America. [1] It was first described by Hermann Burmeister , for whom the species is named, in 1865.
Spectacled porpoise: circumpolar in cool sub-Antarctic and low Antarctic waters Phocoena phocoena: Harbour porpoise: cooler coastal waters of the North Atlantic, North Pacific and the Black Sea Phocoena sinus: Vaquita: northern area of the Gulf of California, or Sea of Cortez Phocoena spinipinnis: Burmeister's porpoise: coast of South America
Little is known about the diets of other species of porpoises. A dissection of three Burmeister's porpoises shows that they consume shrimp and euphausiids (krill). A dissection of a beached Vaquita showed remains of squid and grunts. Nothing is known about the diet of the spectacled porpoise. [18]
As with other porpoise species, the spectacled porpoise has no beak. It has small pectoral fins with rounded tips positioned far forward on the body, and a triangular dorsal fin. This porpoise species shows obvious sexual dimorphism between adult males and females, as the dorsal fins in males are much larger and more rounded than those of ...
The monodontids, oceanic dolphins (Delphinidae) and porpoises (Phocoenidae) together comprise the Delphinoidea superfamily. Genetic evidence suggests the porpoises are more closely related to the white whales, and these two families constitute a separate clade which diverged from the Delphinidae within the past 11 million years.
An endangered orca vanished from a dwindling whale pod off the Washington coast, a conservation group said. The missing Southern Resident killer whale, K-26, was not seen by researchers during an ...
The harbour porpoise is a little smaller than the other porpoises, at about 67–85 cm (26 + 1 ⁄ 2 – 33 + 1 ⁄ 2 in) long at birth, weighing 6.4–10 kg. Adults of both sexes grow to 1.4 to 1.9 m (4 ft 7 in to 6 ft 3 in). The females are heavier, with a maximum weight of around 76 kg (168 lb) compared with the males' 61 kg (134 lb).
