They use their long claws to hang onto branches while they feast on the leaves that other animals can't reach. The sloth's long claws — 3 to 4. Scientific name: Choloepus didactylus; IUCN status: Listed; Habitat: Venezuela, Suriname, French Guiana, Guyana, Brazil, Equador and Peru – tropical moist. Becky Cliffe is a British zoologist working at the Sloth Sanctuary of Costa Rica, currently “I want to be a sloth scientist” I have been living, breathing, and working with sloths for 6 years now, and although I have met many passionate people.Mystery of the Pooping Sloth - Science on the Web #55
It has two separate ranges, split by the Andes. One population is found from eastern Honduras  in the north to western Ecuador in the south, and the other in eastern Peru, western Brazil, and northern Bolivia. Ancient sloths were not arboreal but dwelled on land, and were the size of bears. The Megatheriuma widespread species was larger than an elephant.
Additionally, the nothrotheriid Thalassocnus of the west coast of South America became adapted to a semiaquatic marine lifestyle. Initially they just stood in the water, but over a span of four million years they eventually evolved into swimming creatures. As well as ground sloths this family included Thalassocnusa genus of semi- or fully aquatic sloth. They disappeared shortly after the appearance of humans about 11, years ago. Evidence suggests human hunting contributed to the extinction of the American megafauna.
Ground sloth remains found in both North and South America indicate that they were killed, cooked, and eaten by humans. Megalocnus survived on the Antilles until about years ago, long after other ground sloths died out on the mainland, but then went extinct when humans finally arrived there too. Two-toed sloths are slightly larger. While almost all mammals have seven cervical vertebraetwo-toed sloths have only six, while three-toed sloths have nine,  allowing them to rotate their heads through degrees.
They also have poor hearing. Thus, they rely on their sense of smell and touch to find food. In most mammals, hairs grow toward the extremitiesbut because sloths spend so much time with their limbs above their bodies, their hairs grow away from the extremities to provide protection from the elements while they hang upside down. In most conditions, the fur hosts symbiotic algae, which provide camouflage  from predatory jaguarsocelots and harpy eagles.
These include biting and blood-sucking flies such as mosquitoes and sandfliestriatomine bugsliceticks and mites.

Sloths have a highly specific community of commensal beetlesmites and moths. Incidentally, it appears that sloths benefit from their relationship with moths because the moths are responsible for fertilizing algae on the sloth, which provides them with nutrients.
Muscles make up only 25 to 30 percent of their total body weight. Most other mammals have a muscle mass that makes up 40 to 45 percent of the total body weight. On three-toed sloths, the arms are 50 percent longer than the legs.

While they sometimes sit on top of branches, they usually eat, sleep, and even give birth hanging from branches.
They sometimes remain hanging from branches even after death. On the ground, the maximum speed of sloths is 3 metres 9. Sloths are surprisingly strong swimmers and can reach speeds of They spend 90 per cent of their time motionless.
Two-toed sloths have a diverse diet of insects, carrion, fruits, leaves and small lizards, ranging over up to hectares. Spider monkeys flounce in the tree branches. Two bats cling to the inside of a hollow tree. Stingless bees swarm around a honey-like goop oozing from a freshly cut log. Ant birds keep guard over a bustling ant highway, and a land crab scuttles out of the way of our plodding feet. With all the wildlife vying for my attention, I just about pass the foot radio tower, when Horan calls it out.

I tilt my hat back, wipe the sweat from my brow and look up. The tower, like the soaring trees surrounding it, is the first evidence of the island being wired. An aerial view of the six-square-mile research island in the Panama Canal would reveal six other towers poking through the treetops—all part of a cutting-edge animal surveillance system scientists call the Automated Radio Telemetry System, or ARTS.
Atop each tower is an array of antennas that, every few minutes, receives signals from up to 20 radio-tagged animals roaming the forest. The towers then communicate real-time information on the locations and activity levels of the animals to an on-site laboratory. In the past, the scientists spent a sizable amount of time on a variety of projects running through the forest, tracking tagged animals with hand receivers.
They researched the radio towers and transmitters and decided that Barro Colorado Island BCIwhere the Smithsonian Tropical Research Institute has an outpost, was the ideal place to test them.
The field station, which has been around since the s, has labs that can support the system and dormitories to sleep the nearly scientists who visit and conduct studies on the island each year. The seven towers were erected inand the first data began streaming into the computer lab in Once an animal is collared, the towers check in on the creature every four to five minutes, 24 hours a day, seven days a week. When one flat-lines on the computer, researchers know that either it, or its transmitter, is dead and to go out in the forest to assess the damage.
The two-and-a-half-hour hike Horan and I take is enough to convince me of this.

We trek along riverbanks hoping to spot a trolling crocodile or a bathing tapir, but are greeted by some turkey-like crested guan instead. We pass cages along the trail as well. Hoots, chirps and the guttural wails of howler monkeys fill the humid tropical forest.
Here, a howler monkey climbs a tree branch just outside the dormitories. Megan Gambino Three-toed sloths are among the animal species studied by Smithsonian scientists in Panama. Megan Gambino Rodent-like agoutis eat some seeds from an island tree called Dipteryx and bury others for later.
But ocelots prey on the agoutis, thus allowing some of the buried seeds to grow into trees.
