How many chambers does an octopus heart have?

three chambers
A frog, which is an amphibian, has a heart with three chambers (one ventricle and two atria), and fish hearts have two chambers (one atrium and one ventricle). An octopus heart system contains three hearts—one main heart (H1) pumping blood to the body and two other hearts (H2 and H3) pumping blood to the gills.
