Fishes possess normal differences that range from gill numbers

Fishes possess normal differences that range from gill numbers, arches, and length of the filaments. The most observable is the differences in overall length in fish sizes than determining the gill length by a microscope while held on the stage and measurements are taken directly using vernier calipers. Studies that have been conducted led to the observation of a spectacular difference that the number of red muscles was directly proportional to the length of the fishes.

After a series of research was carried out on different fishes which included various marine fishes, Researchers were amazed at the fact that one of the fishes had the inverse of the proposition that had been stated. Tuna had the contrary with a decrease in the amount of the red oxidizing muscles. This has now been stated to be a normal endowment possessed by the Tuna fish. It is therefore the purpose of this paper to establish the normality of the Tuna’s diminished amount of red muscle as opposed to the increasing amount observed in many fishes.
