They can weigh up to 8kg and are covered in long, blonde, and brown fur. They have a naked face and long limbs with two claws on their front limbs and three claws on their back. Algae often grow on their fur, sometimes making them appear green in color.
The major difference between the two-fingered and three-fingered sloths in Costa Rica are;
- Two-fingered with 2 fingers and Three-fingered with 3 fingers.
- Two-fingered sloths are mainly one color, and often light tan throughout their body with their face being slightly darker. Three-fingered have a darker 'mask' like face as well as a darker brown fur. The males will have an 'eye' on their backs. This is a spot where the color is lighter brown with a dark brown almost black thin oval.
Technically, two-toed sloths should be called two-fingered sloths as they have three toes on their feet, but just two fingers on their hands, while three-toed sloths have three toes and three fingers.
