What is an organism that uses camouflage?
Camouflage can change with the environment. Many animals, such as the arctic fox, change their camouflage with the seasons. Octopuses camouflage themselves in response to a threat. Other species, such as nudibranchs—brightly colored, soft-bodied ocean “slugs”—can change their skin coloration by changing their diet.
What is it called when an animal is dark on top and light on the bottom?
Countershading, or Thayer’s law, is a method of camouflage in which an animal’s coloration is darker on the upper side and lighter on the underside of the body. This pattern of light and shade makes the object appear solid, and therefore easier to detect.
What does camouflage mean for animals?
“Camouflage refers to the use of a combination of materials, illumination or colouration that makes an animal blend in with its environment, or makes it harder to spot. Some types of camouflage are also used to disguises animals as something else.”
What are the two types of disruptive coloration?
There are two types of deceptive coloration: camouflage and mimicry.
How are members of the same species similar to each other?
Members of the same species are similar both in their external appearance and their internal physiology; the closer the relationship between two organisms, the more similar they will be in these features.
What is the definition of a different species?
Strictly, the definition is that two groups of animals are of a different species if they cannot interbreed. So – cats and dogs are obviously different species – nobody would dispute that because there are no cat/dog hybrids.
What are some examples of phenotypic differences between species?
Species’ appearance can be misleading in suggesting an ability or inability to mate. For example, even though domestic dogs ( Canis lupus familiaris) display phenotypic differences, such as size, build, and coat, most dogs can interbreed and produce viable puppies that can mature and sexually reproduce.
Why can’t two species breed with two different directions?
Different species may have different genes that are active in development; therefore, it may not be possible to develop a viable offspring with two different sets of directions. Thus, even though hybridization may take place, the two species still remain separate.
