Sloth

Sloths are arboreal mammals of the Neotropical forests of Central and South America, known for their slow movement and hanging posture in trees.

Updated September 11, 20261 min readCited sources

Sloths are slow-moving, tree-dwelling mammals native to Central and South America. They belong to the order Pilosa and are closely related to anteaters.

What it is

Sloths are arboreal mammals known for their hanging posture and extremely slow movement. They spend most of their lives in the tropical forest canopy of Central and South America, feeding primarily on leaves.

Key details

Living sloths are divided into two families: two-toed and three-toed sloths. Major references recognize six extant species. They typically weigh 3.6–7.7 kg and measure 0.6–0.8 m. Their diet consists mostly of leaves, with some fruits, shoots, and sap.

Why it matters

Though sloths have no native range in Canada, they are widely featured in Canadian zoological collections and conservation education. Their unique adaptations and slow lifestyle make them a popular subject for wildlife media and rainforest awareness campaigns.

In short

  • Sloths are found only in Central and South America.
  • They are divided into two-toed and three-toed families.
  • Their diet is mainly leaves.
  • They are related to anteaters, not monkeys.
Canadian angle

Sloths have no native range in Canada, but they are widely featured in Canadian zoological collections, conservation education, and wildlife media coverage.
