Blood vessels in the wrists and ankles prevent cramps, which allows them to climb for long periods of time. The claws on the feet help grasping. The eyes are very large, focused forward and lifted upward, but the color resolution of vision is not high. The ears are short and hidden under the short hair on the pinna. They are more stout than other species of the family Loris, and have a stronger sense of smell. The short, thick fur can be a variety of colors, with the red part of the fur being larger than that of other slow loris, and some are chestnu
