However, the two-toed sloth is a placental mammal. Placental mammals are mammals in which the developing embryo receives nutrients and oxygen from the mother through a placenta, rather than through an egg yolk.
Is a two toed sloth monotreme marsupial or placental mammal?
The two-toed sloth is not a monotreme. Monotremes are mammals that lay eggs, and the two-toed sloth gives birth to live young.
