杰斐逊收到的树懒是巨爪地懒，大约有一吨重。但还比不上大地懒，大地懒可重达六吨， 和一头大象一样重。

Huge elephantine forms, the mastodon, the hippopotamus, the tapir, antelopes of monstrous size, the megatherium, and the myledon—all, for the moment, in juxtaposition.

A leading British ethno-biologist, wrote the Economist in 1995, thinks a megatherium, a sort of giant ground sloth which may stand as high as a giraffe ... may lurk in the fastnesses of the Amazon basin.

“一位著名的英国民族生物学家认为，”《经济学家》杂志l995年写道，“有一种高如长颈鹿的大地懒，有可能出没在亚马孙河流域僻静的丛林里。”
