Fish

They are vertebrate animals that live in water and breathe with their gills, cold-blooded, double-eyed hearts, mostly scaly bodies, and usually reproduce with eggs. Some species reproduce by giving birth. Consisting of an atrium and ventricle, their hearts always contain dirty blood. Since the dirty blood coming out of the heart is cleaned in the gills, clean blood circulates in the body. While the water taken from the mouth is thrown out of the gills, the oxygen dissolved in the water is given to the blood by osmosis.

What Do Fish Eat?

Fish feed on insects, insects and plants in their natural habitat. Along with these, they survive by eating worms, insect larvae and corals that grow in water. Seasonal changes in the natural environment of fish affect their nutrition. While they find plenty of food in the spring season, their reproduction also increases.
