Crocodiles may have had an ancestor that was starting down the path to being warm-blooded. Crocodiles are related to dinosaurs and their modern descendants, birds, which also have four-chambered hearts. The four-chambered heart allows for more efficient blood circulation.
The heart of crocodiles has a more complex structure compared to other reptiles. It has a four-chambered heart similar to birds and mammals, allowing for efficient oxygenation of blood. This adaptation enables crocodiles to have greater endurance and performance in aquatic environments.
no because it have four chambered heart
Crocodiles and alligators
Most reptiles have a 3-chambered heart. Crocodiles and alligators have a 4-chambered heart.
Most certainly. All vertebrates have a heart. Most reptiles have a three-chambered heart, but alligators and crocodiles have a four-chambered heart.
Crocodiles are reptiles not amphibians.
A four-chambered heart
yes but my question was why?
Crocodiles, alligators, caimans and gharials all have four-chambered hearts.
Birds, all mammals, and crocodiles all have four chambered hearts
In turtles, the heart has two atria and a single ventricle partially divided by a wall of tissue called a septum. In crocodiles, there are two atria and two separate ventricle.
Pretty much for the same reasons as us - it's simply nature. Dinosaurs also had a four-chambered heart. Unlike mammals, crocodile's right ventricle pumps blood throughout the body. Such a heart perfectly separates blood going to the lungs from that going to the body, which is a requirement for the high blood flow rates and high metabolic rates characteristic of warm-bloodedness. However, living crocodiles are cold-blooded, so it didn't make sense for them to have a warmblooded heart - a mystery!
