Antechinus do not have a complete pouch, as in other marsupials, but simply a flap of skin covering the teats. [1] The number of teats in Antechinus species varies between different populations of the same species, [ 2 ] [ 18 ] and can be anywhere from six to 13. [ 18 ]
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia.They are natively found in Australasia, Wallacea, and the Americas.One of the defining features of marsupials is their unique reproductive strategy, where the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen.
The pouch is a distinguishing feature of female marsupials, monotremes [1][2][3] (and rarely in the males as in the yapok [4] and the extinct thylacine); the name marsupial is derived from the Latin marsupium, meaning "pouch". This is due to the occurrence of epipubic bones, a pair of bones projecting forward from the pelvis.
Didelphimorphs have a plantigrade stance (feet flat on the ground) and the hind feet have an opposable digit with no claw. Like some New World monkeys, some opossums have prehensile tails. Like most marsupials, many females have a pouch. The tail and parts of the feet bear scutes. The stomach is simple, with a small cecum. [9]
The water opossum (Chironectes minimus), also locally known as the yapok (/ ˈjæpɒk /), is a marsupial of the family Didelphidae. [2] It is the only monotypic species of its genus, Chironectes. [3] This semiaquatic creature is found in and near freshwater streams and lakes from Mexico through Central and South America to Argentina and is the ...
Numbat. The numbat (Myrmecobius fasciatus), also known as the noombat or walpurti, [4][5] is an insectivorous marsupial. It is diurnal and its diet consists almost exclusively of termites. The species was once widespread across southern Australia, but is now restricted to several small colonies in Western Australia.
The Virginia opossum is the original animal named "opossum", a word which comes from Algonquian wapathemwa, meaning "white animal". Colloquially, the Virginia opossum is frequently just called a "possum". [8] The term is applied more generally to any of the other marsupials of the families Didelphidae and Caenolestidae.
Males are generally larger than females. In addition, the coat of the male tends to be reddish at the shoulders. As with most marsupials, the female brushtail possum has a forward-opening, well-developed pouch. [7] The chest of both sexes has a scent gland that emits a reddish secretion which stains that fur around it.
