The animal kingdom can be harsh. What to do if you are a small animal trying to defend yourself or a predator who wants to stealthily stalk their prey? Evolution's answer—camouflage. While we often think of the chameleon as the perfect example of camouflage, in reality, things are much more complex.
Two types of camouflage tactics exist, one that makes animals difficult to see—crypsis—and one that disguises them as something else—mimesis. Crypsis, the most common type of animal camouflage, is often achieved because the animal's colors resemble its environment. However, this is not the only way that animals can blend into their surroundings.
Other forms of crypsis include animals that have patterns, stripes, or other markings that deliberately make it difficult to perceive the outlines of their bodies. Jaguars and the common frog are two examples of animals with this disruptive coloration. Other animals, such as butterflies and certain types of lizards, go to great lengths to eliminate their shadows, a technique that was employed by military camouflage during WWII.
Some camouflage animals will even reinforce their disguise by mimicking certain behaviors. For instance, the leafy seadragon actually sways like the seaweed it disguises itself as. And, of course, there are animals who adapt their coloration to the environment. The Arctic hare will shed its coat, moving from winter white to brown or gray in the summer.
With mimesis, animals camouflage themselves as something that would be of little interest, whether a dead leaf or a twig. In doing so, these animals are passed over by predators who mistake them for something different or barely notice them at all. With myriad choices for disguise, animals of all types turn to camouflage to help their survival.
In celebration of the animal kingdom's beauty, check out more than 23 animals that camouflage themselves. Can you spot them all?
23 Animals That Camouflage Themselves
Leaf-Tailed Gecko
A leaf-tailed gecko has adapted to blend directly into tree branches in Madagascar. It even looks like it has the same texture as tree bark, making it an excellent disguise.
Vietnamese Mossy Frog
The Vietnamese mossy frog may be small, but it has a clever defense mechanism against larger predators. As its name suggests, it merges with a mossy floor.
Mountain Hare
Hares aren't the first animal that comes to mind when we think of disguise, but a mountain hare's white coat makes it nearly invisible for predators to find in the snow.
Arctic Fox
The Arctic fox has a coat equipped to live in the frigid Arctic regions. Its fluffy, snow-white fur allows it to blend in with the icy landscape, helping it hide from predators.
Although the Arctic fox has camouflage, its white coat isn’t permanent. Like many animals, it replaces its winter fur with a shorter summer coat that ranges from gray to brown. This also has a camouflage effect, however, and blends in with grass and shrubs that appear after the snow melts.
Goldenrod Crab Spider
We don't usually think of spiders as camouflage artists, but some definitely are. The goldenrod crab spider is one such example. It has a bright yellow color that helps it match the flower, ultimately aiding its hunt for prey.
Western Diamondback Rattlesnake
The Western diamondback rattlesnake wouldn't be such a fearsome predator if it didn't have a camouflage that made it blend in with the tawny desert background.
Green Sea Turtle
On land, a sea turtle's shell makes it stand out. But underwater, this sea creature perfectly matches its habitat.
Great Rockfish
As its name suggests, the rockfish spends most of its time hiding among the rocks. Its red coloring and rough texture help it do just that without going noticed.
Gray Cracker Butterfly
When this butterfly opens its wings, it reveals a pattern that mimics the texture and colors of a tree.
Eastern Screech Owl
It's no accident that the plumage of an eastern screech owl helps it match the trees that it inhabits.
Leafy Seadragon
Related to the seahorse and pipe fish, sea dragons are famous for their masterful camouflage skills.
Hobart's Red Glider Butterfly
When this butterfly lands on top of red leaves or flowers, it becomes one with nature.
Mediterranean Octopus
Deep in the ocean, the common octopus (or Mediterranean Octopus) has the ability to blend in with the colors and textures of rocks and aquatic life found there.
Perinet Chameleon
The chameleon is the most famous camouflage artist, but how does it change its color? Well, it comes down to its biology. This reptile—as well as some other reptiles and cephalopods—has chromatophores which are cells containing pigment, and they react to sunlight and the brightness of the background. This helps match the chameleon's skin to his surroundings.
Tawny Frogmouth
The tawny frogmouth is a bird found that has gray-colored plumage to help it blend with the vegetation in Australia and Tasmania.
Jaguar
The jaguar's patterned fur can help it blend in with branches and trees so it can better sneak up on its prey.
Pink Pygmy Seahorse
The pygmy seahorse may be small, but its background matching skills are among the best. Its pink camouflage makes it indistinguishable from aquatic life in the coral reef.
Dead Leaf Butterfly
Many animals would not guess that this leaf-mimicking insect is actually a butterfly.
Stone Fish
Lurking at the bottom of the ocean floor is the colorful stone fish. Its appearance is very deceiving, however, as it also has 13 spikes filled with dangerous venom.
Sand Crab
A sand crab is a clever crustacean that you can find across the coasts of North America. At least, if you know where to look. Its camouflage makes it nearly one with the sand.
Two-Tailed Spider
This arachnid is almost impossible to see when it lies against the tree.
Leaf Katydid
If you take the time to look at the leaves, keep a close watch out. You might find a leaf katydid.
Ghost Pipefish
Not many are familiar with this aquatic creature, but it is one of the best camouflaged animals around.
