These two sloths are not only different species, but they belong to two completely different families, separated by over 30 million years of evolution. Cross-species adoptions like this are incredibly rare in the wild, with only 3 other documented observations of this happening.

Although it was on display for a long time at the Museum of La Plata, Argentina, its age was uncertain. A new study indicates that giant ground sloths lived 13,000 years ago and coexisted with the first humans of South America.

September 28th is The International Day for Universal Access to Information (IDUAI), a day that, despite this digital age, goes largely unrecognized.

A giant sloth weighing five tons and whose height could exceed twice that of a human being was part of prehistoric Costa Rica seven million years ago.

What is the skeleton of a Sloth like? What are their claws made of? The internet is full of ‘facts’ about sloths. You will be surprised to know how much of this information is untrue.

Hace seis años, la fundadora de SloCo, Dra. Rebecca Cliffe, lanzó un importante proyecto de investigación sobre la genética de perezosos en Costa Rica.

Camera traps and trail cameras are commonly used outdoors for wildlife research and they are now also playing an increasingly important role in the conservation and preservation of endangered species.

Why do scientists sometimes feel the need to jump to extra conclusions, just so that they can have an eye-catching story for the media?

Hiding deep within the remote jungles of South America, there is an elusive and commonly overlooked species of sloth clinging onto survival.

The Sloth Sanctuary of Costa Rica have now received 9 orphaned baby sloths showing birth defects.
