Circulatory system of Long Finned Squid
Image of the three different hearts in the squids circulatory system
Heart: Unlike any of the other animals on this website the long finned squid has three separate hearts
Two Branchial Hearts: These two hearts provide blood to the gills of the long finned squid. These are located around the larger systemic heart that is responsible for pumping blood around the body
Systemic Heart: Similar to the Northern Leopard Frog the main systemic heart of the long finned squid has three separate chambers. However unlike the frog the long finned squid has a lower ventricle and two upper auricles.
Hemocyanin- Unlike the human the Long Finned Squid uses hemocyanin to transport oxygen instead of hemoglobin. This allows their blood become colorless when there is not sufficient oxygen.
Comparision: The squid and human circulatory system are very different, however they are both closed circulatory systems
