Elegant Fat-tailed Mouse Opossum
The elegant fat-tailed mouse opossum (''Thylamys elegans''), also known as the Chilean mouse opossum, is an opossum from central Chile. The type species of ''Thylamys'', it was first described by English naturalist George Robert Waterhouse in 1839. This medium-sized opossum is characterized by black rings around the eyes, white limbs, gray to light brown coat, lighter flanks and underbelly and a thick long tail covered with hairs. It is crepuscular (active mainly around twilight) and lives in nests in tree hollows or under rocks and roots. This opossum feeds mainly on arthropods and larvae apart from fruits. Litter size is typically between 11 and 13. The elegant fat-tailed opossum can occur in a variety of habitats – from cloud forests to chaparrals. The IUCN classifies the opossum as least concern. Taxonomy and etymology The elegant fat-tailed mouse opossum is the type species of ''Thylamys'', and is placed in the family Didelphidae. It was first described by Englis ...

George Robert Waterhouse
George Robert Waterhouse (6 March 1810 – 21 January 1888) was an English naturalist. He was a keeper at the department of geology and later curator of the Zoological Society of London's museum. Early life George was born in Somers Town to James Edward Waterhouse and Mary Newman. His father was a solicitor's clerk and an amateur entomologist. He was the brother of Frederick George Waterhouse, who also became a zoologist. George went to school at Koekelberg, near Brussels. He returned to England in 1824 and worked as an apprentice to an architect. Part of the work was in designing the garden of Charles Knight in the Vale of Health, Hampstead and the ornamentation for St. Dunstan's Church. Natural history George became interested in entomology through his father and he founded the Entomological Society of London along with Frederick William Hope in 1833 with himself as honorary curator. He became its president in 1849–50. He wrote articles for Knight's ''Penny Cyclopædi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patagonian Opossum
The Patagonian opossum ''(Lestodelphys halli)'' is the sole species in genus ''Lestodelphys''. Distribution The Patagonian opossum occurs further south, in Argentina, than any other living marsupial. Although distributed throughout some parts of southern Argentina, it is one of the least known mammals of South America. They have been spotted near Monte Phytogeographic Province, and in Patagonia Phytogeographic Province, yet there are no records of Patagonian opossums in central Patagonia, which leads mammalogists to believe that they can only live in the Patagonian steppe. There are two areas in the Patagonian steppe where these animals are often found: the province of La Pampa and Choele Choel (northern Rio Negro Province). Form It is suggested that the Patagonian opossum may have emerged from the same ancestral group as ''Marmosa''. They resemble each other closely. In the winter both types have similarly thickening at the base of the tails, where fat accumulates. Yet they do n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Sciences
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific meth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
