Binturongs are sexually dimorphic (with two distinct gender forms): females are up to 20% larger than males. They have long, coarse, shiny black fur often tipped with gray, yellow, or cream, while their whiskers and the edges of their ears are white with long black tufts of hair. Their particularly muscular tail is usually longer than their body and is prehensile (has the ability to grasp) at the tip. Their cheek teeth are flat to crush the fruit they eat.
