How do you distinguish between two types of sloth?

To distinguish between two types of sloths, such as the two-toed sloth and the three-toed sloth, observe their claws: the two-toed sloth has two long claws on its forelimbs, while the three-toed sloth has three shorter claws. Additionally, the three-toed sloth has a distinct facial pattern with a more pronounced snout and a lighter fur color, while the two-toed sloth tends to have darker fur. Behaviorally, the two-toed sloth is generally more active and can be seen moving more frequently than the three-toed sloth, which tends to be more sedentary.
