About Me

Hi my name is Hanna Gates. I am a senior at Olathe North High School and currently enrolled in E-comm. I spend the last 3 hours of my day at school doing graphic design. You can usually find me at Spencer Gifts in the Great Mall because I work there after school every day, but when I do have time I love to go out and party with my friends.

amanda faucett CAMOUFLAGE AND MIMICRY

Being able to hide from your predators is part of surviving in the animal kingdom. If you are not able to burrow or dive into water you must be able to blend in with your environment. Camouflage and mimicry are the most interesting forms of surviving in your environment. They are both very different.

An animal who can camouflage is able to blend in with their environment. A predator will camouflage to catch prey and the prey will camouflage to keep from getting eaten.Daylight savings time or temperature change triggers a hormone that causes their skin to change. The katydid can blend into almost any environment with leaves.


One of the biggest uses for camouflage is when the seasons change. In the spring and summer there is trees and grass, so an animal can be brown or gray. During the winter when there is snow on the ground that exact same animals coat can turn white. Keeping it safe all through the year and ensuring the survival of their species.


Mimicry is using shape, color, and pattern to look like another animal, often one that is stronger and more feared than them. There are different types of mimicry. Mullerian mimicry occurs when the mimic is also well-defended. Speed mimicry occurs when a sluggish, easy to catch prey species resembles fast moving or hard to catch species that predators have given up trying to catch. Wasmannian mimicry occurs when the mimic resembles it's host (the model) in order to live within the same nest or structure. For example, several beetles closely resemble ants. The ants provide them with food, shelter and protection and can not distinguish them from other colony members. Batesian mimicry occurs when the model is more highly defended than the mimic.

The monarch butterfly tastes bad to birds, so they don't even go near them. The viceroys butterfly mimics, or copies, the pattern and color of the monarch butterfly's wings so that birds will leave it alone, too.

One of the snakes in the picture below is venomous and the other one is its mimic. Coral snakes are very easy to see because of their bright red, yellow, and black stripes. They are colored this way so that other animals know they are dangerous and will leave them alone. The Scarlet Kingsnake looks almost EXACTLY like the Coral snake, but it is perfectly harmless!

The one on the left is the harmless scarlet kingsnake.

Both of these ways are key for other wise helpless animals. Without these adaptations who knows if small insects would have survived up until now.

Camouflage and Mimicry By: Matt Tomlinson



Camouflage and mimicry are adaptations some animals use as protection from predators. Animals that use camouflage look like things in their environment. It might look like a twig, a rock, or a leaf.

Mimicry:
Animals that use mimicry use the colors they have to look like a other animal. For example, countless moth, butterfly, and freshwater fish species have "eye-spots", large dark markings that are flashed momentarily to startle a predator and allow the prey to escape. Mimicry is less often used in catching prey, but is still done today. Preditors use mimicry to help them look less threatening to fool the prey as to it's orgin of attack. For example, turtle species nd Catfish have tongue extensions that are used to lure and attract prey to a position where they become an easy catch. One of the most interesting examples of self-mimicry is the two-headed snake of Central Africa which has a tail that resembles a head and a head that resembles a tail.



Camouflage:
A different approach is camouflage, animals seek to look inedible to avoid predators and prey. Sensory abilities of animals are beneficial to be able to detect camouflaged animals, or the crypsis characteristic. Crypsis is usually most effective when an animal is still. Cryptic animals that are active during the day may be "sit-and-wait" predators, they have the ability to blend into their background. Cryptic animals may be active predators in the dark and use their crypsis while inactive. For example, Katydids are nocturnal insects which use their cryptic coloration to remain unnoticed during the day when they are inactive. They remain perfectly still, often in a position that makes them blend in better.




There are three forms of mimicry: Batesian mimicry, Muellerian mimicry, and self-mimicry. Mimicry is the similarities between animal species; camouflage are animal species resembling an inanimate something.


Batesian mimicry is two or more species that are similar, but only with spines, stingers, or toxic chemistry, while its apparent double lacks these traits.

Muellerian mimicry is two unpalatable species that mimics each other with coloration.
Self-mimicry is a term for animals that have one body part that mimics another to increase survival during an attack or helps the them look dead.



Mimicry helps the animal to not get eaten by making it look like a predator instead of prey. Camouflage hides it so it doesn't get eaten or so it can sneak up on its prey. Mimicry helps by copying looks of other animals so that predators won't be eating them, camouflage helps by copying the looks of their surroundings so that some predators won't be seeing them.
