3-Toed Sloth and Tamarin Monkey
The three-toed sloths are aboreal (tree dwelling) mammals from South and Central America. They go to the forest floor once a week to defecate so are usually spotted high up in the canopy on a favored tree for eating their preferred greens. They can be hard to spot! The coarse fur is often a greenish color due to algae growing on it. They certainly can "hang out" using those beautiful long claws.
They are the only members of the genus Bradypus and the family Bradypodidae. This might be the brown-throated sloth being seen in Panama.
The brown-throated sloth is a species of three-toed sloth found in the neotropical ecozone. It is the most common of the four species of three-toed sloth, and is found in the forests of South and Central America.
