They come from an ancient line of mammals, and there were once dozens of species including the giant ground sloth, which was the size of a small elephant and one of the only animals big enough to eat avocado pits whole and disperse them.
Ei provin dintr-o linie străveche de mamifere, care avea zeci de specii, incluzând leneșul gigant de pământ, care era cam cât un elefant mai mic. Erau printre singurele animale care mâncau avocado cu tot cu sâmbure, și apoi eliminau sâmburele.
