Who it is

• Scientific name: Bradypus variegatus
• Family & relatives: A slow tree mammal in the group Xenarthra, related to two-toed sloths and, more distantly, to anteaters and armadillos.
• How to spot it: A shaggy, slow-moving animal with long curved claws, a round face with a gentle smile, and greenish fur from tiny algae.

Its body & abilities

• Size: Head and body about 42 to 80 cm long.
• Weight: About 3.5 to 4.5 kg (8 to 10 lb).
• Body & adaptations: Its long hooked claws let it hang from branches for hours, and tiny algae in its fur give it a green tint that helps it hide.
• Top speed: One of the slowest mammals, it creeps along at only about 4 meters per minute.
• Strength: Its real strength is its grip; strong hooked claws let it hang upside down without any effort.
• Senses: A good sense of smell and touch, with fairly weak eyesight and hearing.
• Growing up: A single baby is born up in the trees and clings to its mother's belly for months while it grows.

Where it lives

• Habitat: Tropical rainforests, where it spends almost its whole life high in the trees.
• Where in the world: Central and South America, from Honduras south to northern Argentina.
• Territory: Each sloth quietly roams a small patch of forest, moving among a few favorite trees.

What it eats

• Diet: A plant eater that munches leaves and gets most of its water from the leaves it eats.
• Favorite foods: Mostly leaves, plus some buds and tender shoots from rainforest trees.
• How it hunts: It does not hunt; it slowly reaches out to pull leaves close and nibbles them at its own gentle pace.

How it behaves

• How it moves: Climbs slowly hand over hand and, surprisingly, is a strong swimmer when it reaches water.
• When it is active: Rests and sleeps much of the day and moves a little more at night, always slowly.
• Family life: Mostly solitary, spending its peaceful life alone except for mothers with a baby.
• How it talks: Quiet animals; mothers and babies keep in touch with soft bleats and squeaks.
• Babies: After about six months a mother gives birth to one baby, which rides on her and nurses as it grows.

Its place in nature

• Role in nature: It helps the rainforest by nibbling leaves and spreading seeds, and its green fur is a tiny home for algae and insects.
• Conservation: The brown-throated three-toed sloth is listed as Least Concern, though forest loss is a growing worry.
• Dangers: The biggest danger is losing rainforest homes to tree cutting, plus road crossings between forest patches.

Life & legacy

• How long it lives: Around 20 to 30 years in the wild.
• In our culture: A gentle symbol of taking it slow, the sloth has become a beloved star of books, films, and memes.
• Where to see it: Rainforests of Costa Rica, Panama, and the Amazon, plus reputable wildlife sanctuaries.
• Fun fact: A sloth comes down from its tree only about once a week and can hold its breath for up to 40 minutes.
