At first, this might seem like an easy question to answer, but it is difficult to define what makes a fish a fish because there is so much diversity among animals that we consider to be fishes. What makes a fish a fish? Fish have scales for protection.

Vertebrates Are Animals That Have A Backbone Inside Their Body.

Types of fish fish come in more varieties than any other group of vertebrate animals. An adaptation is a characteristic of an organism that improves its chances of surviving and/or reproducing. What is adaptation bbc bitesize?

Nearly Half Of All Vertebrates (Animals With Backbones) Are Fish.

The spine and the bones coming off. Considering fick’s law, in order to maximise the rate of gas exchange, fish have many gill filaments covered in lamellae, maximising the surface area available.in order to maximise the concentration gradient, the gills have a good blood supply to ensure that oxygenated blood is removed from the gills as quickly. An organism's adaptations are a result of the genes the organism inherits from its parents.
