All living things

All living things use some way to survive and defend themselves. Frogs use their skin in many ways for these reasons. So how do frogs use their skin, color and poison to survive and defend themselves? In this paper you will learn how frogs use their skin to live, survive and defend themselves. Frog skin is thin and naked. It has no scales, no hair, and no feathers. However, the skin of a frog is critical to their survival. Through it, they both drink and breathe. They also use their skin to absorb all the moisture they need through their skin because they do not swallow. Although frogs do have lungs, they rely on the extra oxygen they absorb through their skin, especially when theyre underwater. Frogs must keep their skin moist. Otherwise, oxygen cant pass easily through their skin and they suffocate. Frog skin secretes a mucus that helps them keep moist. Even so, their skin tends to dry out which is why they usually stay near bodies of water. They rely on dew for moisture or burrow themselves underground in moist soil. Although they rely on their skin for a lot of purposes they do rejuvenate themselves by shedding their skin once a week. This process consists of a lot of twisting, bending and stretching to loosen the skin. Once the frog has loosened ! it enough it pulls the skin over its head like a sweater and usually eats it. I have been describing simple and logical reasons for the importance of frog skin. However, there are more reasons to make it all the more fascinating. In frogs, pigmentation or skin color depends on the presence of specialized cells and the resulting optical phenomena. These cells are differentiated from the so-called neural crest during the stage when the brain and the spine are being formed and then migrate to the surface of the skin. The evolutionary history of the biology of pigmentation may be dry material, but it is the basis for the dazzling ...
