About the Perch

Perches can be found in the fresh waters of Eurasia and North America. They move around depending on the time of year or day. They are carnivorous. The perch is very popular among fishermen, both for sport and food. Perches are very adaptable and can live in almost any type of fresh water. They also have special teeth called palatines that allow them to eat smaller fish.

Circulatory System

The circulatory system is a low pressure, single loop system. The blood becomes oxygenated once it passes by the gills, then continues on the loop back to the heart. The heart has two chambers and contains four parts. All veins, ventricles, arteries, and capillaries are in charge of letting blood flow through the heart in the cycle.
