What dinosaurs had 8 hearts?
Such an enormous pressure would require a very large, strong and slow-beating heart. But, they postulate, instead of a single large heart, the Barosaurus probably had some eight hearts. Thus the primary heart would generate only sufficient pressure to pump blood to the next heart and so on.
Do Worms have 5 hearts?
An earthworm has five hearts that are segmented and pump blood throughout its body,” said Orsmond. She said their structure was provided by a “hydrostatic skeleton” coelomic fluid (fluid within the body cavity) held under pressure and surrounded by muscles. “There are over 5 500 named species of earthworms worldwide.
