flying lemur; colugo
Refers to the animal order Dermoptera, not a true lemur. In Japanese, often written in katakana as ヒヨケザル.
The flying lemur inhabits the tropical rainforests of Southeast Asia.
Have you ever seen a colugo at the zoo?
The name ヒヨケザル (日避猿) literally means 'sun-avoiding monkey', likely from the animal's nocturnal habits. The exact origin is uncertain.
