Better known as flying lemurs, colugos are arboreal mammals often seen gripping onto tall tropical tree trunks across South-East Asia, with two species: Sunda and Philippine. Sometimes mistaken for bats, their closest relatives are actually primates. They can’t fly, but a membrane that extends between their limbs works like wings, allowing them to glide great distances from tree to tree or from the canopy down to the ground, like miniature wingsuit pilots.

Where to see? Flying lemurs are found across South-East Asia, including the Philippines, Malaysia, Vietnam, Cambodia and Laos. The Malaysian island of Langkawi is a good spot, with some hotels taking guests on nature walks to locate the otherwise hard-to-find tree-huggers.
