Introduction This paper will clearly display a diagram of an organism of the student’s choice. This organism will display all of the main structures of the primary organs by labeling. Careful research will exhibit the concepts of natural selection and adaptation. Selected organism will address the proper concepts that apply. Three physiological adaptions were investigated by the student. Upon conclusion of the student’s investigation, knowledge will grant the understanding of how physiological adaptions allow the selected organism to thrive in its ecological niche. The organism that was selected for this essay is the Fish.

Explanation of why nuisance species like the Fish share an equal importance to the economy and to ecology. Fish evolution and adaption process has produced many species that are a great contribution to mankind in many aspects. INTERNAL ANATOMY
There are many variations of fish; who are defined as animals. Fish represents the most common living vertebrates. Currently, there are an estimation of at least 25,000 species of fish who are living today and this number is growing. The cold-blooded fish have a backbone and fins. In addition, fish breathe through an airway named gills. Fish have skin however, on top of the skin is scales. There are some fish who do not have scales; as catfish who only have skin. Fish are able to steer, stop, move, maintain their position and stop by using their fins. The location of these fins vary in different fish. As for the scales on fish they vary as well.
