Red-tailed Squirrel
The red-tailed squirrel (''Sciurus granatensis'') is a species of tree squirrel distributed from southern Central America to northern South America. Distribution It is found in Central and South America (Colombia, Costa Rica, Ecuador, Panama, and Venezuela) and the Caribbean islands of Trinidad and Tobago and Margarita. According to the Global Register of Introduced and Invasive Species it has also been introduced and is invasive in Cuba, however this refers to a small population found around some parts of the margin of Rio Almendares in Havana that escaped from the Havana Zoo. Habitat Ranges from in elevation. It inhabits many types of forests, and can be found in picnic grounds. Taxonomy It was recently reclassified as ''Notosciurus granatensis'' in 2015, ''Notosciurus'' being a genus created in 1914 by Joel Asaph Allen for a juvenile of this species. However, the IUCN still puts it as a member of the genus ''Sciurus''. Infraspecific variability This is an extremely variabl ...

Joel Asaph Allen
Joel Asaph Allen (July 19, 1838 – August 29, 1921) was an American zoology, zoologist, mammalogy, mammalogist, and ornithology, ornithologist. He became the first president of the American Ornithologists' Union, the first curator of birds and mammals at the American Museum of Natural History, and the first head of that museum's Department of Ornithology. He is remembered for Allen's rule, which states that the bodies of endotherms (warm-blooded animals) vary in shape with climate, having increased surface area in hot climates to lose heat, and minimized surface area in cold climates, to conserve heat. Early life Allen was born in Springfield, Massachusetts, the son of Joel Allen and Harriet Trumbull. He studied and collected specimen of natural history early in life, but he was forced to sell his relatively large collection so that he could attend the Wilbraham & Monson Academy in 1861. The following year, he transferred to Harvard University, where he studied under Louis Agassi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1811
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Rodents Of Central America
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Once included with rodents, rabbits, hare ...

Mammals Of Venezuela
The fauna of Venezuela consists of a huge variety of animals. Venezuela's diverse wildlife includes manatees, Amazon river dolphins, and Orinoco crocodiles, which have been reported to reach up to in length. Some 23% of reptilian and 50% of amphibian species that inhabit the country are endemic to Venezuela. Overall, around 8,000 species (the world's 5th highest total) are endemic to the country. Venezuela hosts a total of 1,417 bird species, more than 351 mammals, 341 reptiles, 315 amphibians and more than 2,000 freshwater and marine fishes. Invertebrates groups have not been inventoried exhaustively, but among the well known groups there are around 900 species of marine molluscs, 1,600 butterflies, over 120 dung beetles species and 39 species of blowflies.Capelo, Juan C., Buitrago, Joaquín. 1998: Distribución geográfica de los moluscos marinos en el oriente de Venezuela.

Mammals Of The Caribbean
A unique and diverse albeit phylogenetically restricted mammal fauna is known from the Caribbean region. The region—specifically, all islands in the Caribbean Sea (except for small islets close to the continental mainland) and the Bahamas, Turks and Caicos Islands, and Barbados, which are not in the Caribbean Sea but biogeography, biogeographically belong to the same Caribbean bioregion—has been home to several family (biology), families found nowhere else, but much of this diversity is now extinct. The bat faunas of much of the Caribbean show similarities that led to the proposal of a distinct Caribbean faunal region, bounded by "Koopman's Line". This region excludes several of the region's islands, including the Grenadines, Grenada, Trinidad, Tobago, and other islands near the American mainland, such as Isla Margarita, Margarita, Isla Escudo de Veraguas, Rosario Islands, Cozumel, and the Florida Keys. The faunas of islands outside Koopman's Line are similar to those of the adj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richmond's Squirrel
Richmond's squirrel (''Sciurus richmondi'') is a poorly known tree squirrel in the genus ''Sciurus'' endemic to Nicaragua, which is likely a synonym of the red-tailed squirrel (''Sciurus granatensis''). It is locally known as the ardilla del rama. Taxonomy It was first described in 1898 by Nelson based on a series of specimens collected in 1892. Specimens were collected again in 1908 and 1910 by Joel Asaph Allen. No more specimens were then collected until 53 were taken in the 1960s. Description Very similar to the ''Sciurus granatensis'' ssp. ''hoffmanni'', but smaller in size, coloured less brightly, and with lighter coloured hairs on the tail. It has a brown back and tail, the tail streaked with tawny yellowish hairs, and an orange abdomen. Females have noticeably wider cheekbones than the males, but are otherwise morphologically identical (aside from the obvious). Distribution Endemic to Nicaragua. It has mostly been collected in the lowlands on the Atlantic coast, from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andean Squirrel
The Andean squirrel (''Sciurus pucheranii'') is a tree squirrel endemic to Colombia where it inhabits montane rain forest and cloud forests of the Cordillera Occidental and Cordillera Central ranges of the Colombian Andes, at elevations between . It is a small species with a body length of about and a similar length tail. It has soft, silky, reddish-brown fur, a darker tail and yellowish-grey underparts. It is thought to be diurnal but has been little studied, and the International Union for Conservation of Nature has rated its conservation status as being data deficient. Description The Andean squirrel is a typical tree squirrel, in its general proportions resembling the Eastern grey squirrel of North America. However, it is much smaller, with a body length of only about , and a tail. Although there are few records of its weight, it appears to be generally between about . It has soft, silky, reddish-brown fur over most of the body, merging to greyish-yellow on the underparts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
