Sloth Facts For Kids & Adults: Pictures, Information & Video. Discover The Slowest-Moving Animal In The Rainforest!

Sloths are tree-dwelling mammals that live in the rainforests of South and Central America. In this article, which is part of our Rainforest Animals series, we’ll look at the sloth’s life and habitat, and learn where it fits within the rainforest ecosystem. At the end is a list of sloth facts for kids.

Watch the videos further down the page to see sloths in the wild!

Sloth Information

Sloths are arboreal (tree-dwelling) mammals that live in the rainforests of South and Central America. They are named after the deadly sin of sloth (which means laziness) because they move extremely slowly.

Sloths move so slowly that algae (plant-like organisms) grow in their fur! This is actually beneficial to sloths, as it gives them a slightly greenish color, helping them to blend in with their surroundings!

Sloths spend most of their lives in the trees, where they hang upside-down from branches and vines. Sloths eat, sleep, mate and even give birth while hanging around in the trees!

Due to the design of their feet and long, curved claws, sloths can hang upside down with little or no effort. This actually makes them a less appealing target for human hunters because even when shot, sloths remain hanging in the trees.

Sloths are mostly nocturnal, and sleep during the day.

Sloth Information

They’re slow enough when in the trees, but sloths are even slower on the ground!

6 Species, 2 Families

There are six species of sloth, divided between two families: two-toed sloths (Megalonychidae) and three-toed sloths (Bradypodidae).

You can tell the difference between the two families by counting how many ‘fingers’ they have. Two-toed sloths have two fingers; three-toed sloths have three.

Perhaps they should have been named two and three fingered sloths; both families of sloths have three toes on their hind legs!

Two-toed Sloths (Megalonychidae family)

Hoffmann's two-toed sloth

Hoffmann’s two-toed sloth

There are two species of two-toed sloth:

  • Linnaeus’s two-toed sloth (Choloepus didactylus) (Conservation status: Least Concern)
  • Hoffmann’s two-toed sloth (Choloepus hoffmanni) (Conservation status: Least Concern)

Two-toed sloths are slightly larger and faster-moving than three-toed sloths. They are around 60 cm – 70 cm (24 – 28″) in length, and weigh about 6 kg (13 pounds).

Three-Toed Sloths (Bradypodidae family)

Brown-throated sloth

Brown-throated sloth

There are four living species of three-toed sloth:

  • Brown-throated sloth (Bradypus variegatus) (Conservation status: Least Concern)
  • Maned sloth (Bradypus torquatus) (Conservation status: Vulnerable)
  • Pale-throated sloth (Bradypus tridactylus) (Conservation status: Least Concern)
  • Pygmy three-toed sloth (Bradypus pygmaeus) (Conservation status: Critically Endangered)

Three-toed sloths are smaller and slower than two-toed sloths. They grow to around 45 cm – 60 cm (18 – 24″) in length and weigh around 4 kg (9 pounds). Although their tails are longer than those of the two-toed sloths, they are still quite short, reaching 6–7 cm (2–3 in) in length.

Sloth Facts: What Do Sloths Look Like?

Sloths have fairly small, thin bodies with short tails. Their heads are small and round, with short snouts, small ears, and large eyes surrounded by dark masks. The shape of their mouths gives them a permanent smiling expression!

Sloths have long, curved claws. These can grow to be up to 3 – 4 inches (8 – 10 cm) long. Sloths use their claws to climb trees and to hook themselves onto branches.

The long limbs and claws of a sloth are designed for hanging and climbing, not for walking on the ground. Sloths have great difficulty getting around when on the floor, as this video shows …

A Living Habitat!

The sloth’s long, shaggy hair is home to algae, small plants and bugs such as moths and beetles. This is due to a combination of the sloth’s slow speed and the warm, damp climate of the rainforest.

Sometimes the sloth will even lick algae and plants off of its fur as a snack!

What Do Sloths Eat?

Sloths are folivores (specialist leaf-eaters), and also eat buds and shoots. Their bodies and lifestyles reflect their diet. Leaves contain very little energy and are also low in nutrients. As a result, sloths have large and complex stomachs, which contain bacteria that break down the leaves.

It can take a sloth a month to completely digest a meal! Sloths climb down from the trees in order to urinate and defecate (poop!) only about once a week. The contents of a sloth’s stomach account for as much as two-thirds of its body weight.

Because leaves contain very little energy, sloths have a low metabolism (the rate at which energy is used by an organism).

Two-toed sloths have been observed eating insects, lizards and birds in addition to plant matter.

How Fast (Slow?!?) Is A Sloth?

Sloths move extremely slowly, only managing to cover about 6 – 8 feet (1.8 – 2.4 meters) per minute.

As a (not very scientific) comparison, walking at your normal speed you’d probably be moving at about 275 feet (84 meters) per minute. That’s close to the length of a standard soccer / football pitch.

So even when walking you’re about 39 times faster than a sloth!

Deep Sleepers

Sloths spend most of their time either eating or sleeping. In the wild, sloths sleep between 9 and 15 hours a day.

Can Sloths Swim?

They may not be very good on the ground, but sloths are good swimmers. They use a lazy, doggy-paddle stroke to propel themselves through the water.

Keeping Cool

Due to their low metabolism, sloths have the lowest body temperature of any mammal, and can’t shiver to keep warm.

Sloth Predators

Sloths are hunted by several rainforest animals, including jaguars, ocelots, harpy eagles, and green anacondas.

It’s much easier for a predator to spot prey that is moving. Because sloths spend so much time either motionless or moving very slowly, they often avoid detection.

Sloths are very vulnerable when on the ground and tend to spend as little time as possible out of the safety of the trees.

When cornered or feeling threatened, sloths will lash out with their long front claws.

Additional Sloth Facts

  • Thousands of years ago, giant sloths roamed North America. These elephant-sized animals became extinct about 10,000 years ago.
  • Sloths eat, sleep, and live most of their lives hanging upside down.
  • If a sloth feels threatened it might put on a ‘burst of speed’ and travel at 13 ft. (4 m) per minute.
  • Sloths are mainly nocturnal, but some are also known to be diurnal (active during the day).

Sloth Activities For Kids

  • Think about what you can do to help stop deforestation and save the homes of rainforest animals. Write a short story about what you can to do to help save sloths’ homes.
  • Gather some friends for a sloth race! Whoever crosses the finish line last is the winner!
  • Draw a picture of a sloth hanging out in the rainforest canopy. Don’t forget to include the leaves, flower buds and twigs that sloths like to eat!
  • Check out the Sloth Sanctuary in Costa Rica.
