Great article on BBC Earth by Henry Nicholls on the “truth about sloths”, including interviews with Rory Wilson and Becky Cliffe who have pioneered the Sloth Backpack Project.
Reputation: Sloths are lazy and stupid. They have to be because they look it. They are covered in algae. Yuck! They climb to the ground to perform a ritual defecation at the base of a tree, a risky business when there are eagle-eyed, fleet-footed predators around. They are bad at crossing roads. Silly sloths.
Reality: Slowness is the ultimate weapon in an evolutionary war against eagle-eyed, fleet-footed predators. What better way to blend in with the forest than to cosy up with algae and fungi. Ritual defecation is the sloth equivalent of speed dating, just without the speed.
