Sloth slo ho ho Christmas sweater

The dictionary defines “lazy” as “lazy”. Then it makes some sense, that the slowest-moving mammal in the world will have this name. Yet another way of looking at it is that sloths use their resources intelligently and effectively. Sloths diet is often poor in nutrition and difficult to digest, so their metabolism is very slow. Their stomachs are packed to help them digest the tough cellulose, but this is a slow process.
