Lagomorpha
The lagomorphs ( Lagomorpha ) compose one of Mammifères comprising two S:
These animal was classified a long time in the order of the Rongeurs. They are characterized some mainly by their teeth. The latter is characterized by the presence of two pairs of incisors to the upper jaw (one, smaller, being located behind the other and being hidden by it) which are, like those of the mandible, entirely covered with enamel. Because of the resemblances between rodents and lagomorphs, certain authors join together them in the superorder of the Glires.
The lagomorphs are animals whose size can vary from 12 to 25 cm length. They are covered with a dense fur with thick flock and whose color can vary according to the seasons. Their muzzle, equipped with many vibrisses, comprises however a zone of naked skin (Rhinarium). This zone extends from the nostrils to the upper lip, which is split in its medium.
The lagomorphs present an adaptation particular to the Digestion of the Cellulose. Their Intestin has a large Cæcum with function fermentaire in which bacteria attack cellulose by producing volatile fatty-acids which are used as Nutriment S. Moreover, at certain times, the lagomorphs evacuate of this cæcum soft and spherical droppings which they réavalent. This matter rich in vitamins and bacterial proteins is redigérée. It is the cæcothrophie, an adaptation which allows them, like rumination at the Ruminant S, to draw part of cellulose and to increase their proteinic ration whereas they have a mode strict vegetarian.
