Aposematic coloration and cryptic coloration are two types of protective colorations shown by animals. Overview and Key Difference 2. What is Aposematic Coloration 3. What is Cryptic Coloration 4. Similarities Between Aposematic and Cryptic Coloration 5.
Aposematic coloration or warning coloration is a protective coloration shown especially by small animals including insects, mites, spiders, and frogs.
These species tend to be colored brightly, and they carry a high detection risk. However, these prey species are often poisonous to eat because they produce toxic chemicals inside their bodies.
This aposematic coloration helps the predators to remember these poisonous prey species and to avoid them in the future. However, some animals are able to mimic the color of poisonous species, without producing poisons. Cryptic coloration is a way of protective coloration. This means predators have to spend longer finding them. That's a waste of energy! There are lots of different examples of camouflage. Some colors and patterns help animals blend into areas with light and shadow. The American bittern spends most of its time hidden in the reeds.
When a threat approaches, it either freezes in place or stretches its neck up towards the sky and sways back and forth. The stripes on its breast and belly look like reeds waving in the breeze, and a predator may be fooled! If that doesn't work, it calls out with its loud, booming voice and flies away! Other animals, like the bobcat , have spots that help them blend into their environment. Their spots work the same way the bittern's stripes do. The dark spots blend in with the shadows and the lighter fur blends in with lighter areas of their surroundings, like the sunlight shining on the plants around them.
Disruptive coloration helps break up an animal's outline. This makes it difficult for other animals to see it. You'd think that the black and white stripes of the zebra would make it easy for predators to see it! The main predator of the zebra is the lion. Lions don't like to hunt in the heat of the day, they prefer sleeping in the shade. They hunt as it gets dark. As the sun goes down, the black and white stripes of the zebra help it blend into the tall grass. But the zebra's stripes have another purpose.
Zebras live in herds. Lions like to pick out one member of the herd that looks weak. When the lion attacks, the zebras start running in all directions. With all those stripes mixing together, its easy for the lion to lose the zebra it picked out of the herd. Sometimes an animal blends best into its environment when it is a solid color. The white fur of the polar bear is perfect for an arctic environment.
The red squirrel has reddish-brown fur on top and white fur on its undersides. The darker top fur makes it harder for predators to see the squirrel when it is on the ground.
When it is perched on a tree branch, the white fur on its belly helps it to blend into the lighter sky above. Penguins also have counter shading.
