Water Opossum
The water opossum (''Chironectes minimus''), also locally known as the yapok (), is a marsupial of the family Didelphidae.* It is the only living member of its genus, ''Chironectes''. This semiaquatic creature is found in and near freshwater streams and lakes from Mexico through Central and South America to Argentina and is the most aquatic living marsupial (the lutrine opossum also has semiaquatic habits). It is also the only living marsupial in which both sexes have a pouch. The thylacine, commonly referred to as the Tasmanian tiger, also exhibited this trait, but it is now extinct. The water opossum lives in bankside burrows, emerging after dusk to swim and search for fish, crustaceans and other aquatic animals, which it eats on the bank. Origin of the name The local name for the water opossum, "yapok", probably comes from the name of the Oyapok River in French Guiana. Physical appearance The water opossum is a small opossum, 27-32.5 cm long, with a 36–40 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illiger
Johann Karl Wilhelm Illiger (19 November 1775 – 10 May 1813) was a German entomologist and zoologist. Illiger was the son of a merchant in Braunschweig. He studied under the entomologist Johann Hellwig, and later worked on the zoological collections of Johann Centurius Hoffmannsegg. Illiger was professor and director of the "zoological museum" (which is the Natural History Museum of Berlin in the present day) from its formation in 1810 until his death. He was the author of ''Prodromus systematis mammalium et avium'' (1811), which was an overhaul of the Linnaean system. It was a major influence on the adoption of the concept of the family. He also edited the ''Magazin für Insektenkunde'', widely known as "Illiger's Magazine". In 1811 he introduced the taxonomic order Proboscidea for elephants, the American mastodon and the woolly mammoth. He also described the subspecies ''Odobenus rosmarus divergens'', commonly known as the Pacific walrus. Illiger's macaw (''Promolius m ...

Marsupials Of Central America
Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a pouch. Marsupials include opossums, Tasmanian devils, kangaroos, koalas, wombats, wallabies, bandicoots, and the extinct thylacine. Marsupials represent the clade originating from the last common ancestor of extant metatherians, the group containing all mammals more closely related to marsupials than to placentals. They give birth to relatively undeveloped young that often reside in a pouch located on their mothers' abdomen for a certain amount of time. Close to 70% of the 334 extant taxon, extant species occur on the Australia (continent), Australian continent (the mainland, Tasmania, New Guinea and nearby islands). The remaining 30% are found in the Americas—primarily in South America, thirteen in Central America, and one species, the Vi ...
