(page 121) (...) Miller (1925) and Kellogg (1928) included the true porpoises in the family Delphinidae and did not even grant them subfamily status. However, Slijper (1936) and Fraser and…
(...) Although various sensory mechanisms are present in cetaceans, special navigational problems occur when animals are in a pelagic environment which can minimize available cues. Dawbin (1966) has observed that…
(...) Two separate predation events were documented off the coast of Vancouver Island, British Columbia between the years 2013-2014. Both predation events occurred on small cetaceans from the Phocoenidae family:…
(...) I am enabled to add a new species, through the kindness of Mr. William H. Dall, who has placed at my disposal his notes upon and drawings of two…
(Phocoenid-related excerpts) (...) NEOMERIS Gray This genus appears to have but one character to distinguish it from Phocaena, namely, the absence of a dorsal fin. I was unable to discover…
The behavior of Dall's porpoise was studied in the western Johnstone Strait, British Columbia, during the summer of 1984. Observations and theodolite trackings were made from a cliff-top observation point…
Dall’s porpoise (Phocoenoides dalli) echolocation clicks have not been widely recorded. Concurrent with visual observations, acoustic recordings of free‐ranging Dall’s porpoise were made offshore of southern California using a towed…
To evaluate and quantify sexual dimorphism of skull shape and assess the ontogenetic background for differences, samples of 134 harbor porpoise (Phocoena phocoena) and 85 Dall's porpoise (Phocoenoides dalli) were…
We used 11 restriction endonucleases to study mtDNA variation in 101 Dall's porpoises Phocoenoides dalli from the Bering Sea and western North Pacific. There was little phylogeographic patterning among the…
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…
