Crocodiles have nostrils on the top of their snouts.
Crocodiles have specialized muscles that allow them to open and close a flap in the back of their throat, called the glottis, allowing them to breathe while submerged underwater. They can hold their breath for extended periods of time by slowing down their metabolic rate and conserving oxygen.
They don't, any aquatic reptile needs to return to the surface to breathe after a while, the only creatures that can breather underwater are fish (and all their variants ie: sharks, stingrays etc)
Crocodiles have behavior adaptations such as being stealthy hunters, using ambush tactics to catch prey. They are also known for their ability to regulate body temperature by basking in the sun or cooling off in water. Additionally, crocodiles exhibit strong maternal instincts, with females fiercely protecting their nests and young.
Because crocodiles have to have water.
