What type of circulatory system do crocodiles have?
Crocodilians have a four-chambered heart – just like people! And just like the circulatory system in people, the heart takes in deoxygenated blood from the body, sends it to the lungs to become oxygenated, the blood comes back to the heart, where it will then be pumped to the rest of the body. Pretty straightforward.
How long can a crocodile hold its breath underwater?

Why don’t crocodiles come up for air?
