This animal, as Guapo said, in attacking the turtles, first turns them over, so as to prevent their escape—for the “carapas” are of those tortoises that once upon their backs on level ground cannot right themselves again. He then proceeds to tear out the flesh, and eats it at his leisure. Oftentimes he capsizes a far greater number than he can eat, and even returns to the spot to have a second meal of them; but frequently the Indians wandering along the river, find the tortoises he has turned over, and of course make an easy capture of them.
Guapo, upon this occasion, took advantage of the jaguar's skill, and carried to the camp all that the latter had left. It was Guapo's design to make a large quantity of “turtle sausage-meat,” so that they might have a supply for many days, as by this time even Guapo himself was getting tired of the horse-flesh “charqui.”
They were about returning to camp, when their attention was drawn to two dark objects upon the sand-beach a little farther on. These objects were in motion, and at first they believed they were a pair of “mad tortoises” that had not yet returned to the water, although they were close to its edge.
Led on by curiosity our party approached them, and saw that one only was a tortoise, and one of the largest kind, being nearly three feet in diameter. The other animal was a small caïman or alligator.
As our travellers drew near they saw that these two creatures were engaged in a fierce and deadly combat. Now, it is a curious fact that the larger alligators and crocodiles are among the most destructive enemies which the turtles have, eating thousands of the latter while they are still tiny little creatures and unable to defend themselves; and, on the other hand, that the turtles prey extensively on the young of both alligators and crocodiles, eating them whenever they can catch them! I say this is a curious fact in natural history, and it seems a sort of retaliatory principle established between these two kinds of reptiles, as if they ate one another's offspring en revanche.
There is no feeling of revenge, however, in the matter. It is merely an instinct of appetite by which both kinds will eat almost any small fry they come across. In fact, the alligators and crocodiles not only eat the young of the turtles, but their own young as well. That is, the old males do; and it has been stated, that the males of some species of tortoises have a similar unnatural appetite.
The turtle of which we are speaking is one of the most carnivorous of the whole race, and one of the fiercest in its nature too; so much so, that it has earned the name of the “fierce tortoise.” It will eat fish and small crustacea, and almost any living thing it finds in the water, which is not too large for it. It is extremely expert in catching its prey. It lies concealed at the bottom among the roots of flags and nymphæ; and when any small fish chances to pass it, by means of its long neck darts out its head and seizes upon its unsuspecting victim. Once the bill of the “fierce turtle” has closed upon any object its hold is secure. You may cut its head off, but otherwise it cannot be forced to let go, until it has either captured its prey or taken the piece with it. It will “nip” a stout walking-cane between its mandibles, as if it was no more than a rush.
A very good story is told of a thief and a tortoise. The thief was prowling about the larder of an hotel in search of plunder, when he came upon a large market-basket filled with provisions. He immediately inserted his hand to secure the contents, when he felt himself suddenly seized by the fingers, and bitten so severely, that he was fain to draw back his hand in the most hasty manner possible. But along with the hand he drew out a “snapping” turtle. To get rid of the “ugly customer” was his next care; but, in spite of all his efforts, the turtle held on, determined to have the finger. The scuffle, and the shouts which pain compelled the thief to give utterance to, awoke the landlord and the rest of the household; and before the thief could disengage himself and escape, he was secured and given into custody.
Well, it was just a tortoise of this species, a “snapping turtle,” and one of the largest size, that our travellers now saw doing battle with the caïman. The caïman was not one of large size, else the turtle would have fled from it, not that even the largest caïmans are feared by the full-grown carapas. No; the strong plate-armour of the latter protects them both from the teeth and tail of this antagonist. The jaguar, with his pliable paws and sharp subtle claws, is to them a more dreaded assailant than the crocodile or caïman.
The one in question was some six or seven feet long, and altogether not much heavier than the turtle itself. It was not for the purpose of eating each other they fought. No—their strife was evidently on other grounds. No doubt the caïman had been attempting to plunder the new-laid eggs of the tortoise, and the latter had detected him in the act. At all events, the struggle must have been going on for some time, for the sand was torn up, and scored, in many places, by the sharp claws of both.
