grayi lives by rivers and lakes,[citation needed] which gives it the common name waterside skink.

Despite the warm climate in its native habitat, it prefers relatively cool temperatures in mountainous areas.

If left to swim in deep water, it may appear to drown, but it actually only plays dead.

It is also an excellent climber, equipped with claws that can grip tree trunks and other wooden structures.

[citation needed] It is becoming quite popular as an exotic pet due to its crocodilian appearance and cheap price in the Philippines.
