Total 46 - and in having the teeth generally developed upon an insectivorous rather than a carnivorous pattern, the upper middle incisors being larger and inclined forward, the canines relatively smaller, and the molars with broad crowns, armed with prickly tubercles.
As already mentioned, Thylacoleo was originally regarded as a carnivorous creature, but this view was subsequently disputed, and its diet supposed to consist of soft roots, bulbs and fruits, with an occasional small bird or mammal.
Broom believes Thylacoleo to have been "a purely carnivorous animal, and one which would be quite able to, and probably did, kill animals as large or larger than itself."
The members of this group are always carnivorous or parasitic, and prey upon both vertebrates and invertebrates.
SPARASSODONTA, a zoological name applied to a group of primitive carnivorous mammals from the Santa Cruz beds of Patagonia, represented by the genera Borhyaena, Prothylacinus, Amphiproviverra, &c. By their first describer, Dr F.
For instance, the animal traps of carnivorous plants (Drosera, Nepenihes, &c.) did not, presumably, originate as such; they began as organs of quite another kind which became adapted to their present function in consequence of animals having been accidentally caught.
Adaptive characters are often hereditary, for instance, the seed of a parasite will produce a parasite, and the same is true of a carnivorous plant.
Beetles and larvae are frequently carnivorous in habit, hunting for small insects under stones, or pursuing the soft-skinned grubs of beetles and flies that bore in woody stems or succulent roots.
The adult and immature stages are, however, by no means confined respectively to carnivorous and herbivorous species of mammals.
It is probable that some are carnivorous, either attacking other larvae or subsisting on more minute forms of animal life; but others perhaps feed more exclusively on vegetable matters of a low type, such as diatoms.
The skull is conical, stout and heavy, and the teeth, although sharper and less rounded than those of badgers, are less suited to a carnivorous diet than those of stoats, weasels and martens.
The transition of the larva from the intermediate to the final host is accomplished by the habits of carnivorous animals.
Its etymology has genus of carnivorous mammals (see Carnivora).
Some are said occasionally to resort to berries and other fruit for food, but as a rule they are carnivorous, feeding chiefly on birds and their eggs, small mammals, as squirrels, hares, rabbits and moles, but chiefly mice of various kinds, and occasionally snakes, lizards and frogs.
Although feeding chiefly on roots, fruits and grain, it is also to some extent carnivorous, attacking and eating small quadrupeds, lizards and birds.
The stone-built cases of the carnivorous Hydropsychid larvae are familiar objects in the water of swift streams.
The teeth especially exemplify the carnivorous type in its highest condition of development.
He appears, however, as a general rule, only to kill when hungry or attacked, and not for the mere pleasure of killing, as with some other carnivorous animals.
The desert was full of wild life, the balance of nature being preserved by the carnivorous animals preying on the herbivorous; trees watered by soakage from the Nile protected the undergrowth and encouraged occasional rainfall.
From this point of view the various adaptive modifications of mammalian dentition may be roughly grouped under the headings of piscivorous, carnivorous, insectivorous, omnivorous and herbivorous.
In the dolphins the teeth form simple cones, but in the seals they are often trident-like; while in the otters the dentition differs but little from the ordinary carnivorous type.
This carnivorous adaptation, in which the function is to hold and kill struggling animals, often of large size, attains its highest development in the cats (Felidae).
Accordingly, it was at this epoch that the small ancestral insectivorous mammals first forsook their arboreal habitat to try a life on the open plains, where their descendants developed on the one hand into the carnivorous and other groups, in which the toes are armed with nails or claws, and on the other into the hoofed group, inclusive of such monsters as the elephant and the giraffe.
As regards the number and form of their permanent teeth, at any rate, creodonts present such a marked similarity to carnivorous marsupials, that it is difficult to believe the two groups are not allied, although the nature of the relationship is not yet understood, and the minute internal structure of the teeth is unlike that of marsupials and similar to that of modern Carnivora.
There is the further possibility that creodonts may be directly descended from the carnivorous reptiles; a descent which if proved might introduce some difficulty with regard to the abovementioned theory as to the arboreal ancestry of mammals generally.
Is it not a reproach that man is a carnivorous animal?
