It is arboreal, bright green above; the end of the prehensile tail is usually bright red.
Acrodont, Old World lizards, with laterally compressed body, prehensile tail and well developed limbs with the digits arranged in opposing, grasping bundles of two and three respectively.
They are less strictly nocturnal in their habits; and with one exception live entirely in trees, having in correspondence with this long and powerful prehensile tails.
They are of a lighter build than the ground-porcupines, with short, close, many-coloured spines, often mixed with hairs, and prehensile tails.
- These singular crustaceans have long soft flexible bodies, the eyes stalked and movable, the first antennae small and filiform, the second lamellar in the female, in the male prehensile; this last character gives rise to some very fanciful developments.
The former, with the feet for the most part concealed by the carapace, is subdivided into two tribes, the Ctenopoda, or " comb-feet," in which the six pairs of similar feet, all branchial and nonprehensile, are furnished with setae arranged like the teeth of a comb, and the Anomopoda, or " variety-feet," in which the front feet differ from the rest by being more or less prehensile, without branchial laminae.
The Gymnomera, with a carapace too small to cover the feet, which are all prehensile, are divided also into two tribes, the Onychopoda, in which the four pairs of feet have a toothed maxillary process at the base, and the Haplopoda, in which there are six pairs of feet, without such a process.
The caudal vertebrae vary from a rudimentary condition in the guinea-pig to a great size in the jumping-hare and prehensile-tailed porcupines.
Their colour is black, their skull decidedly round, their hair thick and frizzly, their legs thin and almost without calves, and their toes so prehensile that they can use them nearly as well as their fingers.
The second maxillipeds are developed into powerful prehensile organs, and the branchiae, instead of being connected with the appendages of head and trunk, are developed on the pleopods, appendages of the abdomen.
Tail long, and sometimes partially prehensile when it is used for carrying bundles of grass with which these animals build their nests.
They may, however, be natatory as in many Ostracoda and Copepoda, or prehensile, as in some Copepoda.
The captacula are tactile and prehensile and can be protruded from the anterior aperture of the mantle.
The lips are flexible and prehensile; and the membrane that lines them and the cheeks smooth.
In addition to the absence of prehensile power in their tails, douroucoulis, also known as night-apes, are distinguished by their large eyes, the sockets of which occupy nearly the whole front of the upper part of the skull, the partition between the nostrils being in consequence narrower than usual.
The first pair of limbs is often chelate or prehensile, rarely antenniform; whilst the second, third and fourth may also be chelate, or may be simple palps or walking legs.
- Appendages of 1st pair bisegmented, without poison gland; of 2nd pair prehensile, their basal segments underlying the proboscis, and furnished with sterno 1 to i 1, Somites of the opisthosoma (mesosoma plus metasoma).
Appendages of 2nd pair, strong, usually prehensile and spiny.
They belong mostly to the Cebidae family, and are provided with prehensile tails.
The black rhinoceros (Rhinoceros (Diceros) bicornis) is the smaller of the two, and has a pointed prehensile upper lip. It ranges through the wooded and watered districts of Africa, from Abyssinia in the north to the Cape Colony, but its numbers are yearly diminishing, owing to the opening up of the country.
This animal, also called the bear-cat, is allied to the palm-civets, or paradoxures, but differs from the rest of the family (Viverridae) by its tufted ears and long, bushy, prehensile tail, which is thick at the root and almost equals in length the head and body together (from 28 to 33 inches).
The appendages of the second pair are large and prehensile, as in scorpions, but are armed with spines, to impale and hold prey.
Callosities, or bare patches covered with hardened and thickened epidermis, are found on the buttocks of many apes, the breast of camels, the inner side of the limbs of Equidae, the grasping under-surface of the tail of prehensile-tailed monkeys, opossums; &c. The greater part of the skin of the onehorned Asiatic rhinoceros is immensely thickened and stiffened by an increase of the tissue of both the skin and epidermis, constituting the well-known jointed " armour-plated " hide of those animals.
The mouth of the great majority of mammals is peculiar for being guarded by thick fleshy lips, which are, however, absent in the Cetacea; their principal function being to seize the food, for which purpose they are endowed, as a rule, with more or less strongly marked prehensile power.
From the other genera of that group (Cebinae) with prehensile tails capuchins are distinguished by the comparative shortness of that appendage, and the absence of a naked area on the under surface of its extremity.
The upper and lower margins of the end of the trunk form two nearly equal prehensile lips.
The five-toed feet are of normal structure, and the rat-like tail is prehensile towards the tip. The female has a small pouch.
The tail is long and in some cases prehensile; the first hind-toe may be either large, small or absent; the dentition usually includes three pairs of upper and one of lower incisors, and six or seven pairs of cheekteeth in each jaw; the stomach is either simple or sadculated, without a cardiac gland; and there are four teats.
