Red-foot Tortoise
The red-footed tortoise (''Chelonoidis carbonarius'') is a species of tortoise from northern South America. These medium-sized tortoises generally average as adults, but can reach over . They have dark-colored (nearly black), “loaf”-shaped carapaces (top shell) with a lighter patch in the middle of each scute (shell segment), and a somewhat lighter-colored plastron (underbelly). They also have dark limbs dotted with brightly-colored scales, from which they get their name, that range from pale yellow to vivid or dark red. Visible differences are noted between red-footed tortoises from varying eco-regions. They are closely related to the more easterly-distributed yellow-footed tortoise (''C. denticulatus'') of the Amazon Basin. Their natural habitat ranges from savannah to edge effect, forest edges around the Amazon Basin. They are omnivorous tortoises, consuming a wide assortment of plants, grasses, flowers, fruit and (notably) fungi, as well as the occasional earthworm or o ...

Johann Baptist Von Spix
Johann Baptist Ritter von Spix (9 February 1781 – 13 March 1826) was a German natural history, biologist. From his expedition to Brazil, he brought to Germany a large variety of specimens of plants, insects, mammals, birds, amphibians and fish. They constitute an important basis for today's National Zoological Collection in Munich. Numerous examples of his ethnographic collections, such as dance masks and the like, are now part of the collection of the Museum Five Continents, Museum of Ethnography in Munich. Biography Spix was born in Höchstadt, Germany, the seventh of eleven children. His childhood home is the site of the Spix Museum, open to the public since 2004. He studied philosophy in Bamberg and graduated with a doctoral degree. Later he studied theology in Würzburg. After attending lectures of the young professor Friedrich Wilhelm Joseph Schelling, F. W. J. Schelling, Spix became interested in nature. He quit his theology studies and began studying medic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brumate
Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy. Dormancy tends to be closely associated with environmental conditions. Organisms can synchronize entry to a dormant phase with their environment through predictive or consequential means. Predictive dormancy occurs when an organism enters a dormant phase ''before'' the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase ''after'' adverse conditions have arisen. This is commonly found in areas with an unpredictable climate. While very sudden changes in conditions may lead to a high mortality rate among animals relying on consequential dormancy, its use can be advantageous, as organisms remain active longer and a ...

New World Monkeys
New World monkeys are the five families of primates that are found in the tropical regions of Mexico, Central and South America: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae. The five families are ranked together as the Ceboidea (), the only extant superfamily in the parvorder Platyrrhini (). Platyrrhini is derived from the Greek for "broad nosed", and their noses are flatter than those of other simians, with sideways-facing nostrils. Monkeys in the family Atelidae, such as the spider monkey, are the only primates to have prehensile tails. New World monkeys' closest relatives are the other simians, the Catarrhini ("down-nosed"), comprising Old World monkeys and apes. New World monkeys descend from African simians that colonized South America, a line that split off about 40 million years ago. Evolutionary history About 40 million years ago, the Simiiformes infraorder split into the parvorders Platyrrhini (New World monkeys) and Catarrhini (apes and Old World ...

Margay
The margay (''Leopardus wiedii'') is a small wild cat native to Mexico, Central and South America. A solitary and nocturnal felid, it lives mainly in primary evergreen and deciduous forest. Until the 1990s, margays were hunted for the wildlife trade, at which point the killing of the species was outlawed in most countries; however, years of persecution resulted in a notable population decrease. Since 2008, the margay has been listed as Near Threatened on the IUCN Red List, as the population is thought to be declining due to loss of habitat and deforestation. The scientific name ''Felis wiedii'' was used by Heinrich Rudolf Schinz in 1821 in his first scientific description of the margay, named in honour of Prince Maximilian of Wied-Neuwied, who collected specimens in Brazil. Characteristics The margay is very similar to the larger ocelot (''Leopardus pardalis'') in appearance, although the head is a little shorter, the eyes larger, and the tail and legs longer. It weighs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jaguarundi
The jaguarundi (''Herpailurus yagouaroundi''; or ) is a wild felidae, cat native to the Americas. Its range extends from central Argentina in the south to northern Mexico, through Central America, Central and South America east of the Andes. The jaguarundi is a medium-sized cat of slender build. Its coloration is uniform with two color Morph (zoology), morphs, gray and red. It has an elongated body, with relatively short legs, a small, narrow head, small, round ears, a short snout, and a long tail, resembling Mustelidae, mustelids in these respects. It is about twice as large as a domestic cat (''Felis catus''), reaching nearly at the shoulder, and weighs . Secretive and alert, the jaguarundi is typically solitary or forms pairs in the wild, though captive individuals are more gregarious. Unlike other Sympatry, sympatric cats such as the ocelot, the jaguarundi is Diurnality, more active during the day and hunts mainly during daytime and evening hours. Individuals live in large ...

Jaguar
The jaguar (''Panthera onca'') is a large felidae, cat species and the only extant taxon, living member of the genus ''Panthera'' that is native to the Americas. With a body length of up to and a weight of up to , it is the biggest cat species in the Americas and the List of largest cats, third largest in the world. Its distinctively marked Animal coat, coat features pale yellow to tan colored fur covered by spots that transition to Rosette (zoology), rosettes on the sides, although a melanistic black coat appears in some individuals. The jaguar's powerful bite allows it to pierce the Turtle shell#Carapace, carapaces of turtles and tortoises, and to employ an unusual killing method: it bites directly through the skull of mammalian prey between the ears to deliver a fatal blow to the brain. The modern jaguar's ancestors probably entered the Americas from Eurasia during the Early Pleistocene via the land bridge that once spanned the Bering Strait. Today, the jaguar's range ex ...

Bushdog
The bush dog (''Speothos venaticus'') is a canine found in Central and South America. In spite of its extensive range, it is very rare in most areas except in Suriname, Guyana and Peru; it was first described by Peter Wilhelm Lund from fossils in Brazilian caves and was believed to be extinct. The bush dog is the only extant species in the genus '' Speothos'', and genetic evidence suggests that its closest living relative is the maned wolf of central South America or the African wild dog. The species is listed as Near Threatened by the IUCN. In Brazil, it is called ('vinegar dog') and ('bush dog'). In Spanish-speaking countries, it is called ('vinegar dog'), ('vinegar fox'), ('water dog'), and ('shrub or woodland dog'). Description Adult bush dogs have soft long brownish-tan fur, with a lighter reddish tinge on the head, neck and back and a bushy tail, while the underside is dark, sometimes with a lighter throat patch. Younger individuals, however, have black fur o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Prey
Birds of prey or predatory birds, also known as (although not the same as) raptors, are hypercarnivorous bird species that actively predation, hunt and feed on other vertebrates (mainly mammals, reptiles and smaller birds). In addition to speed and strength, these predators have bird vision, keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talon (anatomy), talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding many piscivorous predators such as storks, Crane (bird), cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily insectivorous bir ...

Giant Otter
The giant otter or giant river otter (''Pteronura brasiliensis'') is a South American carnivorous mammal. It is the longest member of the weasel family, Mustelidae, a globally successful group of predators, reaching up to . Atypical of mustelids, the giant otter is a social species, with family groups typically supporting three to eight members. The groups are centered on a dominant breeding pair and are extremely cohesive and cooperative. Although generally peaceful, the species is territorial, and aggression has been observed between groups. The giant otter is diurnal, being active exclusively during daylight hours. It is the noisiest otter species, and distinct vocalizations have been documented that indicate alarm, aggression, and reassurance. The giant otter ranges across north-central South America; it lives mostly in and along the Amazon River and in the Pantanal. Its distribution has been greatly reduced and is now discontinuous. Decades of poaching for its velvety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Crocodile
The American crocodile (''Crocodylus acutus'') is a species of crocodilian found in the Neotropics. It is the most widespread of the four Extant taxon, extant species of crocodiles from the Americas, with populations present from South Florida, the Caribbean islands of Cuba, Jamaica, and Hispaniola, and the coasts of Mexico to as far south as Peru, Ecuador, Colombia, and Venezuela. The habitat of the American crocodile consists largely of coastal areas. It is also found in river systems, but tends to prefer salinity, resulting in the species congregating in brackish lakes, mangrove swamps, lagoons, cays, and small islands. Other crocodiles also have tolerance to saline water, saltwater due to salt glands underneath the tongue, but the American crocodile is the only species other than the saltwater crocodile to commonly live and thrive in saltwater. They can be found on beaches and small island formations without any freshwater source, such as many cays and islets across the Carib ...

Caiman
A caiman ( (also spelled cayman) from Taíno language, Taíno ''kaiman'') is an alligatorid belonging to the subfamily Caimaninae, one of two primary lineages within the Alligatoridae family (biology), family, the other being alligators. Caimans are native to Central America, Central and South America and inhabit marsh, marshes, swamps, lakes, and mangrove rivers. They have scaly skin and live a fairly nocturnal existence. They are relatively small-sized crocodilians with an average maximum weight of depending on species, with the exception of the black caiman (''Melanosuchus niger''), which can grow more than in length and weigh in excess of 450 kg (1,000 Ib). The black caiman is the largest caiman species in the world and is found in the slow-moving rivers and lakes that surround the Amazon basin. The smallest species is the Cuvier's dwarf caiman (''Paleosuchus palpebrosus''), which grows to long. There are six different species of caiman found throughout the wate ...

Bushmeat
Bushmeat is meat from wildlife species that are Hunting, hunted for human consumption. Bushmeat represents a primary source of animal protein and a cash-earning commodity in poor and rural communities of humid tropical forest regions of the world. The numbers of animals killed and traded as bushmeat in 1994 in West Africa, West and Central Africa were thought to be unsustainable. By 2005, commercial harvesting and trading of bushmeat was considered a threat to biodiversity. As of 2016, 301 terrestrial mammals were threatened with extinction due to hunting for bushmeat including non-human primates, even-toed ungulates, bats, Diprotodontia, diprotodont marsupials, rodents and carnivores occurring in developing country, developing countries. Bushmeat provides increased opportunity for transmission of several zoonotic viruses from animal hosts to humans, such as ''Ebolavirus'' and HIV.
