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 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
