Captions provided by CCTubes – Captioning the Internet! The story of sloths is one of astounding ecological variability, with some foraging in the seas, others living underground, and others still hiding from predators in towering cliffs. So why are their only living relatives in the trees?

Thanks to Ceri Thomas for allowing us to use few sloth reconstructions! Check out more of Ceri’s paleoart at http://alphynix.tumblr.com and http://nixillustration.com

And thanks as always to Franz Anthony and everyone at http://252mya.com for their great paleoart.
