THE SWORD-FISH, (Xiphias gladius,)
Which belongs to the mackerel family, has received its name from its long snout resembling the blade of a sword. It sometimes weighs above one hundred pounds, and is fifteen or even twenty feet in length. The body is of a conical form, black on the back, white under the body; the mouth large, with no teeth; the tail is remarkably forked. The Sword-fish is often taken off the coast of Italy, in the Bay of Naples, and about Sicily. They are struck at by the fishermen, and their flesh is considered as good as that of the sturgeon by the Sicilians, who seem to be particularly fond of it. Other European seas are not destitute of this curious animal.
The Sword-fish and the whale are said never to meet without coming to battle; and the former has the reputation of being always the aggressor. Sometimes two Sword-fishes join against one whale; in which case the combat is by no means equal. The whale uses his tail in his defence; he dives deeply into the water, head foremost, and makes such a blow with his tail, that, should it take effect, it kills the Sword-fish at a single stroke; but the latter is in general sufficiently adroit to avoid it, and immediately rushes at the whale, and buries its weapon in his side. When the whale discovers the Sword-fish darting upon him, he dives to the bottom, but is closely pursued by his antagonist, who compels him again to rise to the surface. The battle then begins afresh, and lasts until the Sword-fish loses sight of the whale, who is at length compelled to swim off, which his superior agility enables him to do. In piercing the whale’s body with the tremendous weapon at his snout, the Sword-fish seldom inflicts a dangerous wound, not being able to penetrate beyond the blubber. This animal can drive its sword with such force into the keel of a ship, as to bury it wholly in the timber. A part of the bottom of a vessel, with the sword imbedded in it, is to be seen in the British Museum.
