Another mail-clad animal of importance is the armadillo of the tropical and temperate regions of South America. He is nocturnal in habits, sleeping in his underground home during the day, and coming out at night to seek for food. This underground home is rather large, and the nursery is well protected from enemies by its location. In it the mother armadillo rears her young until they are large enough to care for themselves.
All species of the armadillos are powerful burrowers, and they are well equipped for their tunnelling in the earth with strong fore limbs. They feed upon all kinds of insects and animal substances. It is claimed that the giant armadillo is a veritable grave-robber and sometimes digs up dead bodies for the purpose of eating them.
These animals are plentiful upon the savannas of South America, and they feast upon the bodies of dead cattle. So hard are their coats of armour that the Gauchos sharpen their Spanish knives, which they always carry, upon them. Should the armadillo be attacked by a man on horseback, he will burrow so rapidly that only by the quickest movements of the man can he be caught; and if he is, watch out for his terrible claws!
No animal is better protected by nature from its enemies than the pichiciago, whose scientific name is chlamyphorus truncatus. This strange little mantle-bearer wears a coat of mail which is as flexible as the human-made coats of armour of olden times, and he is as safe under its cover, which allows him perfect freedom, as if he were under the ground. He is about the size of the ordinary mole, and his general habits are not unlike those of the mole. He is an underground-dweller, with enormous fore-paws, palm-shaped, upon which are five powerful claws. These he uses to great advantage in digging in the earth for insects and for building his home. He has a small snout, reminding one of that of a pig; while his piercing little eyes are deeply hidden in his fur. He is a native of Chile, and because of his shy nature and subterranean habits is rarely seen.
The most interesting feature about this little creature is the cuirass which so perfectly protects his body. Its formation and arrangement is quite unusual; it appears like a number of squared plates of horn, tightly united to short strips of tape, which are sewed together. The cuirass is not connected with the entire body of the animal, but only on the top of the head and along the spine. It covers the entire back, and when it reaches the tail, turns downward, forming a perfect flap, which protects the hindquarters.
The various species of manis are famed for their powerful coats of armour. They, also, belong to the great group of burrowers, and their coats of mail assume both offensive and defensive characters. These mail-bearers are covered with numerous sharp-edged scales, like miniature horns, which entirely overlap one another, like shingles on a house. They are of great hardness, and form a belt which no animal of their regions can penetrate. A revolver shot will produce not the slightest effect upon the body of this iron-protected animal.
These animals are plentiful in India, and when they are molested, they deliberately wind themselves up, coil their tails over their bodies, and remain in conscious security against the fruitless blows of their enemies, who soon weary of the wounds caused from the prickly scales of impenetrable armour.
Instead of wearing heavy coats of mail, certain animals, such as the hedgehog and porcupine, prefer to wear coats covered with needles and pins. Of course, a coat of spines is used purely for protection. And against the attacks of such enemies as dogs, it proves all-sufficient, but it is a well-known fact that pumas and leopards will kill and eat porcupines at all times, paying small attention to their spines, as is shown by the number which are sometimes found sticking in the body of a porcupine-eating animal.
There are several species of this great spine-bearing family; and many of them, especially the true porcupines and the echidnas, have burrows in the ground and thus have a double means of protecting themselves. But others, such as the hedgehog, depend for their protection upon their ability to roll up into a ball, thus presenting a barbed wire protection. Still others live largely in the trees and seek by other means to protect themselves.
One of the most interesting coats of armour is that worn by the porcupine ant-eater—oft-times erroneously called porcupine or hedgehog. He is a native of Australia, and is a powerful burrower. He is marvellously protected by means of a coat of needles or spines which inflict painful wounds on the dog or other enemy that ventures to attack him. In case of danger, he curls himself up into a ball, and defies any one to come near. Not only does he possess the coat of prickles with which he defends himself, but he also has a large perforated claw or spur on each hind foot through which pours an ill-smelling liquid, and these also aid in protecting him. There are several varieties of porcupines which inhabit Asia, Africa, Southern Europe and America.
