This extraordinary plant predator is half blind, half deaf and spends most of its time sleeping in trees. So how does a sloth’s day compare to ours? David Attenborough investigates.

In this amusing and entertaining archive clip from the 2002 BBC documentary series The Life of Mammals, David Attenborough examines the life of one of the world’s most extraordinary plant predators – the sloth.

This extraordinary creature, found in the tropical rainforests of South and Central America, is half blind, half deaf and spends most of its time hanging around half asleep in the treetops. It only moves quickly when Mother Nature calls, and even then, quick is a relative term.

But with very little muscle, and a reaction time only one-fourth as fast as ours, how does a sloth’s day compare to a humans? Attenborough investigates.

Interested in interacting with sloths yourself? At the Amazon Shelter For Animal and Environmental Protection in Puerto Maldonado, Peru, travellers can help look after rescued wildlife such as pumas, monkeys and sloths.
