You know sloths are slow, awkward and very odd looking. But there are plenty of other strange things about them, such as the fact that they only come down from the trees about once a week to go to the bathroom (so to speak).

And that doesn’t only seem strange to us humans. The Aviarios del Caribe sloth sanctuary in Costa Rica rescues a lot of orphaned sloths, who don’t know how to properly do their weekly business and need to be taught before they can be released
