Giant sloth refers to extinct ground sloths from the Americas, especially Megatherium, that lived during the Pleistocene and were much larger than modern sloths.

Context

Giant sloths were massive ground-dwelling herbivores that roamed the Americas during the Pleistocene. They could rear up on their hind legs and used their large claws to pull down branches and defend themselves. These animals are related to today's sloths, but were far larger, with some species reaching lengths of about 6 meters and weights up to 4,000 kilograms. They went extinct around 10,000 years ago, likely due to climate change and human hunting. For more on other giant animals, see the giant squid, giant Pacific octopus, and giant otter. [1]
