They lack incisors and have a large reduction in number of teeth with only four to five sets remaining including canines.

[6] Modern sloths are divided into two families based on the number of toes on their front feet, Choloepodidae and Bradypodidae.

They have longer hair, bigger eyes, and their back and front legs are more equal in length.

Predation mainly occurs when the sloth descends to the ground in order to defecate or change trees.

[7] They mainly eat leaves, but there is lacking data on the extent of their diet due to their nocturnal lifestyle and camouflage.

[7] C. didactylus, similar to other sloth species, have a low rate of metabolism, food intake, and defecation, despite their relatively large body mass and their high volumes of methane production.

[10] This long digestion period appears to cause the sloths’ high volumes of methane production, more than most other, similar herbivores.
