How many hearts does a squid have?
Squid have three hearts: two branchial hearts and one systemic heart. The branchial hearts pump blood to the gills, where oxygen is taken up. Blood then flows to the systemic heart, where it is pumped to the rest of the body. The systemic heart is made of three chambers: a lower ventricle and two upper auricles.

Why do squids have 3 hearts?
Octopuses have three hearts: one pumps blood around the body; the other two pump blood to the gills. ... The three hearts help to compensate for this by pumping blood at higher pressure around the body to supply the octopuses' active lifestyle.
