Circulatory System of Koi

The overall composition of the Koi fish is one that makes this fish a good swimmer and a survivor over the winter months. the internal systems of the Koi are more complex than that of the external make up. The skeleton of this fish is what makes up and holds the interior organs in place as it forms a protective skeletal shell for the organs. The internal organs and tissues placed systematically along with the bones in the Koi make the fish one that is muscular.
