Colugos

Colugos differ greatly in terms of their basic coloring. Their backs are usually shades of brown, brownish gray, or gray sprinkled with light yellow spots. Their undersides can be bright orange, brownish red, or yellow. In general, they have very thick, soft fur on their slender bodies. Their necks are long and their heads can be described as "doglike." Colugos females are slightly bigger than males. The Malayan colugo is the larger of the two species, weighing approximately 4 lb (1.8 kg) and measuring about 25 in (63.5 cm) from head to tail. Colugos have large eyes and very good eyesight, traits essential in judging the distances between trees. They have interesting teeth as well; for reasons unknown, their lower incisors are made up of ten thin prongs each, similar to the structure of a comb.
