feature:

Crocodiles have bodies covered in scales, have four limbs, and usually live in water and on land. They breathe through their lungs and skin rather than using lungs like mammals.

Reproductive methods:

Crocodiles reproduce by laying eggs, which are then placed in a suitable location to hatch. Mammals are viviparous or ovoviviparous, providing placental nutrition to their young.

Mammal characteristics:

Compared with mammals, crocodiles do not have lactation glands for nursing their young, and their young are already capable of survival after hatching without the need for maternal care. Mammal calves usually require prolonged periods of breastfeeding and care.

Crocodiles are carnivorous animals that feed on other animals, such as fish, birds, small mammals, etc. Their food sources and hunting methods are very different from mammals.

To sum up, crocodiles are reptiles, not mammals. They are significantly different from mammals in their evolutionary history, including their reproductive methods, physiological characteristics, and dietary habits. Crocodiles are ancient and fascinating animals that have adapted to a variety of environments and play an important role in their own ecosystems.
