When they are adults, they fly up to the sloths living in the trees and colonize their hair. The moths are weak fliers and once they land on a sloth, they stay put. The moths spend their entire ...
Unlike other ground sloths which put a lot of stress on their hind limbs for locomotion—specifically from standing on two legs —the leg bones of Thalassocnus are slender. Bipedalism also led to shorter tibiae in ground sloths; the opposite is seen in Thalassocnus where the tibiae and femora are about the same length. [19]
The species of sloths recorded to host arthropods include [29] the pale-throated three-toed sloth, the brown-throated three-toed sloth, and Linnaeus's two-toed sloth. Sloths benefit from their relationship with moths because the moths are responsible for fertilizing algae on the sloth, which provides them with nutrients.
During the late Miocene and Pliocene, the sloth genus Thalassocnus of the west coast of South America became adapted to a shallow-water marine lifestyle. [8] [9] [10] However, the family placement of Thalassocnus has been disputed; while long considered a nothrotheriid, one 2017 analysis moves it to Megatheriidae, [1] while another retains it in a basal position within Nothrotheriidae.
Both types of sloth tend to occupy the same forests; in most areas, a particular species of three-toed sloth and a single species of the somewhat larger and generally faster-moving two-toed sloth will jointly predominate. Although similar in overall appearance, the two genera are placed in different families.
