evolution

Not only do the evolutionary features define the look of a shark, but also determine how they survive in the wild. Not all sharks will constantly be searching in a particular area of the ocean for their food. There are three general types of sharks that will move according to the form and function of their body. This includes some sharks that will move at the upper part of the ocean and will move at a slow pace, sharks that will be towards the middle of the ocean and will have a powerful force while swimming and sharks that stay at the bottom of the ocean, moving slowly and finding their food on the ocean floor.
