Five great motions are peculiar to it. First, when used as a fin for progression; Second, when used as a mace in battle; Third, in sweeping; Fourth, in lobtailing; Fifth, in peaking flukes.
First: Being horizontal in its position, the Leviathan’s tail acts in a different manner from the tails of all other sea creatures. It never wriggles. In man or fish, wriggling is a sign of inferiority. To the whale, his tail is the sole means of propulsion. Scroll-wise coiled forwards beneath the body, and then rapidly sprung backwards, it is this which gives that singular darting, leaping motion to the monster when furiously swimming. His side-fins only serve to steer by.
Second: It is a little significant, that while one sperm whale only fights another sperm whale with his head and jaw, nevertheless, in his conflicts with man, he chiefly and contemptuously uses his tail. In striking at a boat, he swiftly curves away his flukes from it, and the blow is only inflicted by the recoil. If it be made in the unobstructed air, especially if it descend to its mark, the stroke is then simply irresistible. No ribs of man or boat can withstand it. Your only salvation lies in eluding it; but if it comes sideways through the opposing water, then partly owing to the light buoyancy of the whale-boat, and the elasticity of its materials, a cracked rib or a dashed plank or two, a sort of stitch in the side, is generally the most serious result. These submerged side blows are so often received in the fishery, that they are accounted mere child’s play. Some one strips off a frock, and the hole is stopped.
Third: I cannot demonstrate it, but it seems to me, that in the whale the sense of touch is concentrated in the tail; for in this respect there is a delicacy in it only equalled by the daintiness of the elephant’s trunk. This delicacy is chiefly evinced in the action of sweeping, when in maidenly gentleness the whale with a certain soft slowness moves his immense flukes from side to side upon the surface of the sea; and if he feel but a sailor’s whisker, woe to that sailor, whiskers and all. What tenderness there is in that preliminary touch! Had this tail any prehensile power, I should straightway bethink me of Darmonodes’ elephant that so frequented the flower-market, and with low salutations presented nosegays to damsels, and then caressed their zones. On more accounts than one, a pity it is that the whale does not possess this prehensile virtue in his tail; for I have heard of yet another elephant, that when wounded in the fight, curved round his trunk and extracted the dart.
