Deppe's Squirrel
Deppe's squirrel (''Sciurus deppei'') is a species of tree squirrel in the genus ''Sciurus'' native to Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. Description ''Sciurus deppei'' varies in individual color. The overall color of the body is gray to yellowish brown or rusty-colored brown, while the face is gray. The legs are dark gray or rust colored. The top of the tail is black with a few white hairs mixed in while the bottom side of the tail is yellowish orange to a rust color, the hairs on the tip of the tail are white. Changes in their fur due to seasons aren't typically seen, except for the white tip on their tail and the patches of hair behind the ears disappear during the summer season. Size varies a little bit in the Deppe's squirrel with the average female being around 287.3 g, HB 210.2 mm, and T 169.4 mm. The males average is 268.3 g, HB 207.2 mm, and T 176.0 mm. Both sexes are close in size, but the females tend t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he greatly increased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammals Described In 1863
A mammal () is a vertebrate animal of the 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 middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 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, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the lar ...

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 ...

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] |
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 ...

Maya Civilization
The Maya civilization () was a Mesoamerican civilization that existed from antiquity to the early modern period. It is known by its ancient temples and glyphs (script).
