Perca fluviatilis
Perches are two species of fish that belong to the family Percidae. They belong to the kingdom of Animalia, under the phylum of Chordata and subphylum Osteichthyes. Confusingly, the name perch may apply to a wide variety of fish. The order to which perches belong to, Perciformes, has its roots in both Greek and Latin. Perke means "spotted" in Greek, while forma in Latin means "shaped."
There are two kinds of perches. One of which, the European perch, is native to Eurasia, while the other, the yellow perch, is native to North America.

Today's Objectives
Students will be learning about the structures, functions, and organs of the circulatory system of a perch. Students will also understand the taxonomy, evolutionary relationships, and the ecology of a perch.
Perch Life Cycle
The life cycle of a perch.
Habitat
Adult perches live in slow-moving, nearshore areas where moderate amounts of vegetation provide the perch cover, food, and protection from predators.
Predators
Predators of perches generally include larger fish, such as Largemouth Bass, Smallmouth Bass, and Walleyes. Birds and other animals can also be considered as predators of perches.

Circulatory System of a Perch
Heart- The center of the circulatory system; a muscular organ that helps blood to circulate.
Atrium- a large muscular chamber that serves a one-way compartment for blood that is about to enter the ventricle.
Ventricle- a thick-walled, muscular chamber, the actual pumping portion of the heart.
Sinus venosus- a thin-walled sac that collects blood from the fish's veins before it flows to the atrium.
Bulbus arteriosus- a large muscular tube that connects to the aorta
Ventrical Aorta- Blood flows through this structure to the perch's gills
Dorsal Aorta- Blood flows through this structure from the efferent arteries. It supplies blood to most of the body.
Capillaries- They allow gas and nutrients to pass out of the blood into the individual cells and waste products to pass out from the cells into the blood.

The Circulatory System At A Glance
Perches have a closed circulatory system with a heart that pumps blood around the body in a single loop. The function of the circulatory system is to supply the body with oxygen, nutrients, and blood, and keep it flowing throughout the body.
