Camouflage And Mimicry:

Mimicry is a situation in which an organism,the mimic, shares characteristic with another organism, the model, through action of a single-receiver or "dupe". This is known as mimicry complex. The model is usually voluntary except in the cases of automimicry.Automimicry occurs inside of a single species. An example being when part of an organism's body resembles anther's.

Camouflage allows a seemingly visible organism to blend in or become very discrete in its surroundings.Camouflage is essentially a form of mimicry. Camouflage is a form of deception.Camouflage can be colors or patterns or both. When organisms are camouflaged, they are harder to find. This means predators have to spend longer finding them.

A tiger's stripes are an example of camouflage. A tiger's stripes help it blend into tall grass.Its golden strips blend in with the grass and the dark brown and black stripes merge with dark shadows. Tigers are the largest of four "big cats". They are the largest feline in the world. Bengal tigers consist of eighty percent of the tiger population.














Polar bears are an example of camouflage. Their seemingly white fur (although it is actually translucent)is a good disguise for them in their arctic surroundings. Polar bears have black skin under their fur. They have small ears and a small head to keep them from losing body heat. The polar bear is a semi-aquatic marine mammal. They have adapted to living on land, in the sea, and on ice. The polar bear is one of the largest carnivores with males weighing 600 to 300 kilograms and females weighing half of what the males do.













Coral snakes are an example of mimicry. Their coloration is similar to that of the milk snake and scarlet kingsnake. Coral snakes have the same coloration as the scarlet kingsnake and milk snakes. They have a coloration of red, yellow, and black stripes. While the scarlet and milk snake are non-venomous the coral snake is venomous. The coloration fools its prey into thinking that it is a non-venomous snake and it is able to easily attack its prey.



















The Viceroy and Monarch butterflies are an example of mimicry. The Viceroy looks almost exactly identical to the Monarch. Monarchs taste disgusting and Viceroy taste good. Predators that eat Viceroy may accidentally eat a Monarch thinking its a tasty Viceroy based upon its appearance.
