Two other species that are present in the vicinity are the Dall's Porpoise
(Phocoenoides dalli) and Pacific White-sided Dolphin (Lagenorhynchus obliquidens).
Risso's dolphin (Grampus griseus), Dall's porpoise
(Phocoenoides dalli), Pacific white-sided dolphin (Lagenorhynchus obliquidens), gray whales (Eschrichtius robustus), blue whales (Balaenoptera musculus), minke (Balaenoptera acutorostrata), humpback (Megaptera novaeangliae) whales, fin whales (Balaenoptera physalus), northern right whale dolphins (Lissodelphis borealis) and killer whales (Orcinus orca) were sighted occasionally or during their migrations.

Items 1 and 4 are the major concern for the estimation of perception bias and for line-transect survey analysis, and it is generally assumed that the observer completes items 2 and 3 correctly or indicates uncertainty correctly (e.g., species code "unidentified porpoise" indicates uncertainty between Dall's porpoise
[Phocoenoides dalli] and harbor porpoise).
Samples of Dall's porpoise
, the most commonly harvested cetacean in Japan, had an average total mercury level of 1.26 ppm, with the highest sample at 2.51 ppm.
In past years, viewers have seen a variety of cetaceans, from gray, humpback, fin, sperm and killer whales to other species like Dall's porpoise
and Pacific white-sided dolphins.
His call comes as animal welfare campaigners plan a demonstration in London in protest at Japanese whalers, who kill some 18,000 Dall's porpoise
a year, according to the Environmental Investigation Agency.
The ship was not diverted if observers felt that group size and species could be determined from the transect line, as was frequently the case of nearby sightings of Dall's porpoise
or large baleen whales.
After about 30 minutes of sailing toward Haro Strait, we saw the unmistakable sign of a Dall's porpoise
: a shiny black dorsal fin.
As much as 30 percent of whale meat sold in Japan may in fact be mislabeled dolphin meat originating from Japanese fisheries like those at Futo Bay [Winter '96-97 EIJ] and the Dall's porpoise
harpoon fishery on Japan's Sanriku Coast.
The most frequently encountered cetacean was the humpback whale (Megaptera novaeangliae; 834 sightings), followed by Dall's porpoise
(Phocoenoides dalli; 521 sightings).
