To move with effort.n. Any member of the mammalian order Cetacea or Cete (which see); an ordinary cetacean, as distinguished from a sirenian, or so-called herbivorous cetacean; a marine mammal of fish-like form and habit, with fore limbs in the form of fin-like flippers, without external trace of hind limbs, and with a naked body tapering to a tail with flukes which are like a fish's caudal fin, but are horizontal instead of vertical; especially, a cetacean of large to the largest size, the small ones being distinctively named dolphins, porpoises, etc.: in popular use applied to any large marine animal. , , n. See blackfish. 2, black-whale, and Globicephalus.n. B. mysticetus is of circumpolar distribution in the northern hemisphere. It attains a length of from 40 to 50 feet, has no dorsal fin, flippers of medium size, and very long narrow flukes, tapering to a point and somewhat falcate. The greatest girth is about the middle, whence the body tapers rapidly to the comparatively slender root of the tail. The throat is smooth; the head is of great size; and the eye is situated very low down and far back, between the base of the flipper and the corner of the mouth. The profile of the mouth is strongly arched, and its capacity is enormous, exceeding that of the thorax and abdomen together. This cavern is fringed on each side with baleen hanging from the upper jaw; the plates are 350 to 400 on each side, the longest attaining a length of 10 or 12 feet; they are black in color, and finely frayed out along the inner edge into a fringe of long elastic filaments. When the jaws are closed, the baleen serves as a sieve to strain out the multitudes of small mollusks or crustaceans upon which the whale feeds, and which are gulped in with many barrels of water in the act of grazing the surface with open mouth. About 300 of the slabs on each side are merchantable, representing 15 hundredweight of bone from a whale of average size, which yields also 15 tons of oil; but some large individuals render nearly twice as much of both these products.n. The southern right whale, B. australis, differs from the polar whale in its proportionately shorter and smaller head, greater convexity of the arch of the mouth, shorter baleen, and more numerous vertebræ. ft inhabits both Atlantic and Pacific Oceans in temperate latitudes, and in the former waters was the object of a fishery during the middle ages for the European supply of oil and bone. This industry gave way to the pursuit of the polar whale about the beginning of the seventeenth century. This whale has long been rare in the North Atlantic, but has occasionally stranded on the European coast, and more frequently on that of the United States. A similar if not identical right whale is hunted in temperate North Pacific waters. Right whales are rare and not pursued in tropical seas, but are objects of the chase in various parts of the south temperate ocean.
