Detailed Solution

The reptile that has a four-chambered heart is the crocodile. Most reptiles like snakes, lizards, and turtles have a three-chambered heart consisting of two atria and one ventricle. But crocodiles are special because they have four chambers — two atria and two ventricles — similar to birds and mammals.

Why This Is Important

The four-chambered heart separates oxygenated and deoxygenated blood completely.
This allows crocodiles to efficiently control blood flow, especially while underwater.
It helps them conserve energy and survive long periods without breathing.

Structure of Crocodile Heart

Chamber	Function
Right Atrium	Receives deoxygenated blood from the body
Left Atrium	Receives oxygenated blood from lungs
Right Ventricle	Pumps deoxygenated blood
Left Ventricle	Pumps oxygenated blood

This unique adaptation makes crocodiles efficient hunters and capable of surviving both in water and on land.
