megalonychidae การใช้

The only extant families of the suborder Folivora are Bradypodidae and Megalonychidae.
Modern sloths are divided into two families based on the number of toes on their front feet, Megalonychidae and Bradypodidae.
For example, two-toed sloths were included within Anthropomorpha, but are now considered to be in the family Megalonychidae, which is not closely related to the primates.
Linnaeus's two-toed sloth and Hoffmann's two-toed sloth ( " Choloepus hoffmanni " ) belong to the family Megalonychidae, which included extinct ground sloths.
Whether these ground-dwelling Megalonychidae were descended from tree-climbing ancestors or whether the two-toed sloths are really miniature ground sloths converted ( or reverted ) to arboreal life cannot presently be determined to satisfaction.
