List of other mammals group

A List of other mammals group or List of other placental mammals group is any mammals group, the various orders.

Carnivora
Carnivora is an order of placental mammals where most species have specialized in primarily eating flesh. However some species are omnivorous, like raccoons and bears, and quite few species like pandas are specialized herbivores. Its members are formally referred to as carnivorans, whereas the word "carnivore" can refer to any meat-eating organism. With at least 279 extant species found on every major landmass and in a variety of habitats, ranging the cold polar regions to the hyper-arid region of the Sahara Desert to the open seas even, Carnivora is the fifth largest order of mammals and one of the more successful members of the group. They come in a huge array of different body plans in contrasting shapes and sizes. The smallest carnivoran is the least weasel, which can weigh as little as 25 g (0.88 oz) and 11 cm (4.3 in), as the largest is the southern elephant seal, whose adult males weigh up to 5,000 kg (11,000 lb) and measure up to 6.7 m (22 ft) in length. All species of carnivorans are descended from a group of mammals which were related to today's pangolins, having appeared in North America 6 million years after the Cretaceous–Paleogene extinction event. These early ancestors of carnivorans would have resembled small weasel or genet-like mammals, occupying a nocturnal shift on the forest floor or in the trees, as other groups of mammals like the mesonychians and creodonts were occupying the top faunivorous niche. However, by the time Miocene epoch appeared, most if not all of the major lineages and families of carnivorans had diversified and took over this niche.

Even-toed ungulate
The even-toed ungulates are ungulates – hoofed animals – which bear weight equally on two of their five toes: the third and fourth. The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, odd-toed ungulates bear weight on one of the five toes: the third toe. Another difference between the two is that even-toed ungulates digest plant cellulose in one or more stomach chambers rather than in their intestine as the odd-toed ungulates do.

Odd-toed ungulates
Odd-toed ungulates, mammals which constitute the taxonomic order Perissodactyla, are hoofed animals—ungulates—which bear most of their weight on one of the five toes: the third toe. The non-weight-bearing toes are either present, absent, vestigial, or positioned posteriorly. By contrast, the even-toed ungulates bear most of their weight equally on two of the five toes: their third and fourth toes. Another difference between the two is that odd-toed ungulates digest plant cellulose in their intestines rather than in one or more stomach chambers as the even-toed ungulates do.

Lagomorpha
The lagomorphs are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae and the Ochotonidae (pikas). The name of the order is derived from the Ancient Greek lagos + morphē. There are ninety-one extant species of lagomorph, including thirty species of pika, twenty-nine species of rabbit and cottontail, and thirty-two species of hare.
