In the sea-lions on the other hand the fore-limbs are free from the skin and body to a much greater extent than in the seals. The 'hand' itself in the sea-lion is exceedingly flexible, although completely enclosed in a horny or leathery skin. The thumbs of this hand further exist in a well developed state; all five fingers being of nearly the same length in the seal. As regards the hind-feet of the sea-lion, these members, like the fore-limbs, are freely separated from the body, at least as far as the ankle and foot are concerned, and the foot is turned outwards, forcibly reminding one of the conformation of that organ in the bear. But we may only note by way of conclusion to these zoological characters that the teeth of the sea-lion are decidedly of a carnivorous type. Any one regarding the skull of a sea-lion could readily form the idea that the animal which possessed it was a flesh-eater. These animals usually possess thirty-six teeth; the 'eye' teeth being of very large size, and so placed in the jaws that any substance entering the mouth is firmly held by these teeth and the adjoining front teeth. The 'grinders' of the sea-lion are small, and do not appear to be of any very great use to the animal. These creatures swallow their food--consisting of fishes, molluscs, and sea-birds--whole, and when a large fish is divided in two, the portion retained in the mouth is swallowed; the portion which tumbles into the water being afterwards seized and duly swallowed in its turn. That the sea-lions are by no means destitute of the craft and cunning of their land-neighbours, is proved by the fact that they capture such birds as the penguins by lying motionless in the water, allowing merely the tip of the nose to appear at the surface. The unwary bird, swooping down upon the floating object, presumed to consist of something eatable, is then seized and devoured by the concealed enemy. Sea-lions may be regarded as the unknown, or at anyrate unrecognised benefactors of the fair sex, inasmuch as, from the rich _under-fur_ which they possess, the favourite material known as 'seal-skin' is obtained. This latter name is entirely misleading in its nature; the much prized material being the produce of the sea-lion and not of a true seal. The possession of this valuable under-fur has contributed very largely to the causes of the indiscriminate attack which has for years past been made upon the sea-lions. The spirit of commercial enterprise has resulted in a war of extermination against these animals in certain regions, from the effects of which it is doubtful if the species can ultimately recover.
