Hide-and-Go-Seek: 7 Cool Critters That Have Mastered the Art of Camouflage
These creatures blend into the environment to evade predators or catch prey.

Goldenrod Spider
Sure, the water spider can spend its entire life underwater, and the flic-flac can somersault through the desert. But this member of the crab spider family can change colors to catch prey. It switches from shades of yellow to white depending on the flower it lands on—usually a daisy or a goldenrod (hence its name). Goldenrod spiders have tiny jaws that contain venom, letting them take on much larger insects, which they grab with their front legs.

Leaf-Tailed Gecko
Its piercing stare and devilish grin make this gecko one diabolical-looking reptile. Endemic to the forests of Madagascar, this smallest member of the leaf-tailed gecko family feeds on insects at night. Because of its ability to resemble dead leaves, it easily avoids those who want to eat it.

Stick Insect
Also known as walking sticks, stick insects resemble the twigs where they live. Many of them play dead to elude predators, and some even shed a limb to break free from foes.

White-Tailed Ptarmigan
This white-tailed ptarmigan’s snowy shade keeps it hidden from predators such as golden eagles and raptors. The only ptarmigan species that dwells south of Canada, it turns mottled gray brown, with white wings, underside, and tail, in the summer and changes to a reddish brown in the fall. Come winter, the ptarmigan is all white except for its eyes and bill. Even its legs and feet are feathered, to help the bird walk on snow.

Chameleon
An exception to the rule, this famous color shifter doesn’t disguise itself against a background; it changes color to control its temperature or to communicate with other chameleons. A cold chameleon turns darker to absorb heat, while hot chameleons become pale to reflect sunlight. To express dominance, males become brighter, but they turn darker during aggressive confrontations. Females signal their willingness to mate through their skin color.

Pygmy Seahorse
Found in the Western Pacific, these miniature seahorses grow to only two centimeters long and match the coral where they live. According to Ocean Portal, the pygmy seahorse is so good at hiding that it wasn’t discovered until its home was being examined in a lab.

Owl Butterfly
Common to the rainforests of Central and South America, this butterfly has wings with large owl-like eyespots that deter avian predators; the wings can span between 5.5 and 6.25 inches. The owl butterfly mostly flies at dawn and dusk and feeds on rotting fruit.
