Saving threatened habitats worldwide

Animals in WLT Reserves - Mammals

Staging site


  • Tiger - Maria Allen
    Tigers are one of the most easily recognised species of big cat, yet they are at risk of extinction. The Bengal Tiger has the largest population of all the sub species of tiger, although they too are endangered.
  • Bezoar Goat
    The Bezoar or Wild Goat is considered to be one of the main ancestors of the modern domestic goat. Like other goat antelopes, Bezoar Goats are stocky, gregarious bovids; gregarious animals tend to form groups or loosely formed communities with others of the same species .
  • Female Bornean Elephant ©Mary Tibbett
    Considered to be a genetically distinct subspecies of the mainland Asian elephant, the largest population of over 200 individuals can be found in the Lower Kinabatangan floodplain area Borneo, where WLT are fundraising to save critically important elephant habitat from the spread of oil palm plantations.
  • A young Orang-utan
    Orang-utans spend almost their whole lives in the tree tops and the protection of the Orang-utan is therefore closely linked to the protection of forest habitat. However, in just 20 years, 80% of orang-utan habitat has been lost, due primarily to logging for the creation of oil palm plantations.
  • Brown-throated Sloth by Lee Dingain
    The Brown-throated Three-toed sloth is a widespread species and found in 3 of WLT’s project areas. However, the species is now considered to be extinct in Argentina where WLT are also working.
  • Capybara by Alan Martin
    The Capybara is the world's largest rodent and can be found across Central and South America, where they spend their lives in forested areas - or in the water: capybaras are excellent swimmers.
  • Endangered Caucasian Leopard
    The Caucasian Leopard, also called the Persian Leopard, is one of the biggest of the eight recognised sub species of leopard (1). All the leopards have stocky bodies with comparatively short legs (1); their total body length (including tail) can be up to 190cm and their weight up to 70kg.
  • Chacoan Peccary by John Burton
    Chacoan Peccary populations are undergoing rapid decline due to the combined forces of hunting and habitat loss. They are only found in hot, dry regions of Gran Chaco and this Chaco habitat in Paraguay is being lost at a very alarming rate.
  • Common Marmoset feeding on a bunch of bananas.
    Marmosets are small New World monkeys with an adult body length of 14-19cm (not including their long tail) and an average adult body mass of 300-500g. The Common Marmoset is also known as the White-tufted-ear Marmoset or Cotton-eared Marmoset; it has a white blaze on the forehead and white ear tufts.
  • Badger by Ian Blacker
    Though badgers are not considered endangered numbers have been depleted. They are protected under various wildlife acts and UK law states that it is an offence to kill, injure or capture a badger, or to interfere with its sett.
  • Hedgehog by Karen Roe
    From Mrs Twiggy-Winkle to Sonic the Hedgehog, this small spiny mammal is a favourite of British wildlife. It is, however, suffering from human presence in its habitat.
  • Geoffroy's Cat
    Small, solitary and predominantly nocturnal, found amongst a wide variety of habitat types including scrubby woodland, dry forests and savannas of the Chaco. Vulnerable to population decline through habitat loss (and previously through hunting for its fur).
  • Giant Anteater. Photo © Hugo del Castillo
    Large, powerful animal that feeds mainly on termites, consuming up to 30,000 a day. Found in a wide range of habitats, from forests and swamps to dry open savannah. The main threats to the Giant Anteater is habitat loss by agricultural encroachment and fires.
  • Giant Armadillo illustration by Bruce Pearson
    With more teeth than any other mammal the Giant Armadillo feed mainly on termites, but also eat other insects and invertebrates, snakes and carrion. The main threat to Giant Armadillos is over hunting for food and habitat destruction.

    Formerly found from Colombia to Argentina, but due to hunting and habitat fragmentation the Giant Otter now exists in isolated patched in Brazil and Paraguay.
  • Golden-headed Lion Tamarins
    The Critically low numbers of Golden Headed Lion Tamarins in the wild are due primarily to habitat loss but this primate also suffers losses from predators (Ocelots, snakes and eagles) and from the pet trade.
  • Guanaco by Lee Dingain
    The Guanaco has been dramatically reduced due to hunting pressures and are now limited to the highlands and foothills of the Andes.
  • Indian Elephants by Marie Chambers
    The biggest threats to elephants are human influence, directly through poaching for tusks and skin and indirectly through habitat fragmentation.
  • Jaguar by Silvia Centron
    After years of being hunted for its fur, the Jaguar is rare in Central America. It is now protected in most parts of its range, but is classified as near threatened.
  • Jaguarundi by Silvia Centron
    Sometimes known as the otter-cat due to its appearance, the Jaguarundi is unlike many other Central and South American species in that it is diurnal and so often sighted during the day.
  • Killer Whale Illustration by Bruce Pearson
    Orcas regularly visit the Patagonian coast to hunt seals and are found in WLT's reserve Ranch of Hopes.
  • Kinkajou by Jack Astbury
    An elusive relative of the racoon, the Kinkajou is also known as the honey bear because it raids bees’ nests for honey.
  • Large Hairy Armadillo by Lee Dingain
    The Large Hairy Armadillo, so named because of its hairy underside and the hair that projects from the scales of the armor, ranges from Southern Bolivia to central Argentina.
  • Tapir walking along a river.
    The hunting of tapirs along with the destruction of its habitat has lead to local extinctions of this mammal.
  • Maned Three-toed Sloth illustration by Bruce Pearson
    Endemic to Brazil the Maned Three-toed Sloth is the rarest of the Sloth Species

    Maned Wolves are found in grasslands, savannah and swamps, where their long legs enable them to see over the tall vegetation. Major threats include loss of habitat due to agriculture encroachment and road deaths of cubs.
  • Margay kitten by Roberto Pedraza Ruiz
  • Muriqui monkey by Neil Burchett
    The Muriqui, also known as the Woolly Spider Monkey, is the largest New World primate and has thick, fleecy fur, which is grey or yellow-brown in colour. Two distinct species are recognised; the Northern Muriqui (B. hypoxanthus) which has a black face and the Southern Muriqui (Brachyteles arachnoides) which has a black face mottled with pink.
  • Ocelot © Kevin Schafer/PfB
    In the past ocelots were hunted for their skins and have since disappeared from many areas. Much of their habitat has been destroyed, and while it is now illegal to trade in dead or alive ocelots, or ocelot parts, enforcement of this protected status is often inadequate.
  • Patagonian Mara
    The Patagonian Mara forages on grasses or shrubs and may spend long periods basking in the sun during the day. By night, it finds shelter in a burrow or amongst dense vegetation. A male and female will form a lifelong pair. Females give birth to an average litter size of two young after a gestation period of 90 days.
  • Proboscis Monkey © LEAP Spiral
    Possibly the most unique monkey in appearance, the Proboscis monkey is known for its extremely large nose and pot belly. It is endemic to Borneo and under threat from habitat destruction.
  • Puma © Fundacion Jocotoco
    Also known as Cougar or Mountain Lion, pumas have be,en hunted because they are regarded as a threat to livestock. Pumas are extinct or very rare in North America and are considerably reduced in other parts of their range.
  • Sloth Bear
    Sloth Bears are unique, being the only bears with a diet that consists mostly of insects, particularly termites. The main threats to the Sloth Bear are poaching and habitat loss or fragmentation.
  • Coati by Emily Y Horton
    Aside from hunting, the biggest threat to the South American Coati (Coatimundi) is the destruction and fragmentation of forest in Central and South America. However the level of threat and the relative decline in numbers is not well known as this species is relatively unstudied.
  • Southern Sea Lions
    The Southern Sea Lion has been a victim of the fur trade in the past, which caused a significant decline in numbers of individuals and in their range. It is now illegal to hunt the species.
  • Southern Elephant Seals by Lee Dingain
    Since the drop in commercial hunting in the 1900's, Southern Elephant Seal populations increased dramatically, however over the last 40 years their numbers have shown a significant decline. Theories suggest that the population overshot the maximum numbers the ecosystem could support and they are dropping back to sustainable levels.
  • Southern Right Whale by Lee Dingain
    Southern Right Whales were once abundant around the coasts of the major land masses in the southern hemisphere, but are now depleted in numbers due to hunting.
  • Spectacled Bear by Lou Jost
    The Spectacled Bear is the only bear found in South America. In previous years they were hunted for meat and sport, which has lead to their drastic decline.
  • Water Opossum illustration by Bruce Pearson
    The Water Opossum also known as the Yapok is the only aquatic marsupial and is found in the freshwater streams and lakes of Mexico and Central and South America.
