Cryptic turtle
A common snakeneck turtle (Chelodina longicollis) covered in camouflaging algae. When resting this individual would look like an algae-covered rock, an example of crypsis, the ability of an organism to avoid observation. Other ways an organism may be cryptic include nocturnality, subterranean lifestyle, and transparency.Photo credit: John O'Neill
