Octopus Three-Heart Cardiovascular Physiology, Blue Blood Hemocyanin, and Distributed Neural Control Systems
Octopuses exhibit an unusual but well-characterized cardiopulmonary and neurophysiological design. A key feature often highlighted in comparative biology is the presence of three hearts: two branchial (gill) hearts that pump deoxygenated blood toward the gills and one systemic heart that circulates oxygenated blood to the rest of the body. This arrangement helps explain how cephalopods… Read More »
