This crocodile is the master of disguise.

A conniving croc inconspicuously floated down a pond at a Thailand zoo, camouflaging itself with a layer of algae.

Photographer Song Kanokrattana spent the day searching for the massive reptiles at the Phuket Zoo with her niece.

But after hours of looking, she was ready to give up.

Just as she was preparing to leave, she caught a glimpse of a big brown eye staring right at her.

The 44-year-old quickly snapped a few shots of the big beast peeking its head out of the water, which later went viral online.
