“I’ve heerd the reason, and it be sensible enough,—more so than to say that it sucks. There was a doctor as belonged in the man-o’-war where I sarved for two years, as was larned in all such curious things. He said that the suckin’-fish be a bad swimmer; and that I know myself to be true. You can tell by the smallness o’ its fins. Well, the doctor, he say, it fastens on to the sharks and ships so as to get carried from place to place, and to the rocks to rest itself. Whenever it takes a notion, it can slip off, and go a huntin’ for its prey; and then come back again and take a fresh grip on whatever it has chosen to lodge itself.”
“It’s that curious thing along the back of its head that enables it to hold on, isn’t it?”
“That’s its sticking-machine; and, what be curious, Will’m, if you were to try to pull it off upwards or backwards you couldn’t do it wi’ all your strength, nor I neither: you must shove it forrard, as you seed me do just now, or else pull it to pieces before it would come off.”
“I can see,” said William, holding the fish up to his eyes, “that there are rows of little teeth in that queer top-knot it’s got, all turned towards the tail. It is they, I suppose, that prevent its slipping backwards?”
“No doubt, lad,—no doubt it be that. But never mind what it be just now. Let us finish flensin’ o’ the shark; and then if we feel hungry we can make a meal o’ the sucker,—for I can tell you it’s the best kind o’ eatin’. I’ve ate ’em often in the South-Sea Islands, where the natives catch ’em with hooks and lines; but I’ve seen them there much bigger than this ’un,—three feet long, and more.”
And so saying, the sailor returned to the operation, thus temporarily suspended,—the flensing of the shark.
