The Colugo Looks Like a Cross Between a Bat and a Monkey, But Is Neither

Weighing as much as a chihuahua, the colugo is an evolutionary anomaly that glides through the Southeast Asian forests. But don't confuse it for a bat or monkey.

Colugos look something like a cross between a bug-eyed pug, a flying fox, and a squirrel. But appearances can be deceiving. These mammals that glide the forests of Southeast Asia occupy a distinct branch of evolution, distantly related to primates.

Also called flying lemurs – though this is a bit of a misnomer as they can’t fly and aren’t lemurs – these quirky-looking creatures live by night in the tropical forests of the Philippines, Vietnam, Malaysia, Myanmar, Indonesia, Thailand, and Singapore.

Is the Colugo A Bat or a Monkey?
