does occur in Azorean waters and has possibly evaded detection so far because of low numbers.

Ontogenetic allometry and body composition of harbour porpoises (Phocoena phocoena
If harbor porpoise had been encountered during this expedition, it is likely that Osgood would have made some reference, as only a month earlier (7 July 1900) he described encounters with "common porpoise, Phocoena

Energy budget of a small cetacean, the harbor porpoise, Phocoena phocoena
For example, the bycatch of species that solely exist within coastal waters of another nation, such as the endangered vaquita, Phocoena
sinus, which occurs only in the territorial waters of Mexico, cannot form the basis of identification.
Seasonal regression in testicular size and histology in harbour porpoises (Phocoena phocoena
It seems unlikely that belugas were missed on these surveys, given that they are easily identified and that our sightings included many small marine mammal species such as sea otters, Enhydra lutris; harbor seals, Phoca vitulina; harbor porpoises, Phocoena phocoena
; and minke whales, Balaenoptera acutorostrata.

Instead, the bones are often categorized as "porpoise" (usually harbor porpoise, Phocoena phocoena
) or "whale" (sometimes "small whale," "large whale," or "baleen whale") (de Laguna, 1956; Yarborough, 1995; McCartney, 1998), making it difficult to determine the extent to which prehistoric societies of the gulf relied on belugas.
