Nineteenth century sealers operating off the coasts of California and Mexico hunted these seals to the brink of extinction, and by the turn of the century the species had been reduced to a few hundred individuals. Seals and sea lions in B.C. It describes the general biology, trends in abundance and feeding habits of species that occur on the B.C. The eastern elk, a subspecies of the elk or wapiti, was also formerly found in Quebec and Ontario, but was made extinct for much the same reasons as the sea mink.

The big free-tailed and evening bats (respectively Nyctinomops macrotis and Nycticeius humeralis), as well as the New England cottontail (Sylvilagus transitionalis) are found mostly in areas south of the U.S.-Canada frontier, and occasionally in Canada. On land they cannot easily raise their head and shoulders and thus tend to remain prostrate. The pelage is usually dark brown and appears almost black when wet. currently numbers about 65,000 and may be approaching historical levels. However, weaned pups, which weigh about 70 kg (150 lbs.
Their streamlined bodies, specialized flippers and insulating layer of blubber allow them to travel and forage at sea with ease. Department of Fisheries and Oceans (DFO) surveys conducted under these conditions indicate that the harbour seal population in Georgia Strait has grown from about 2,100 in 1973 to 12,500 in 1987, a rate of increase of 12.4% per year.
cannot be precisely determined because of the difficulty in estimating the number of seals wintering off our coast. Since 1970, several species have become more abundant off our coast, causing concern among fishermen, who often view these animals as competitors for fish and as a source of damage to their gear and catch.
Recent studies into the feeding habits of sea lions wintering off southern Vancouver Island indicate that they prey mainly upon mid-water schooling fishes. in September-October and depart in April-May.
These include the house mouse (Mus musculus), and Norway and black rats (respectively Rattus norvegicus and R. rattus).

The species was practically exterminated by the 1970s, but a large number of observations since and the capture of a specimen in 1992 have made the species' status in eastern Canada a subject of controversy amongst biologists. During the breeding season, Steller sea lions feed predominantly on octopus and a variety of fish, mainly rockfish.
However, unlike dolphins, porpoises and whales, pinnipeds require land to bear and suckle their young and to rest. and R.J. Harrison (eds.)
