Jaws: Their powerful jaws can generate an enormous bite force, allowing them to crush bones and kill large prey.
Scales and Armor: Crocodiles have thick, tough skin with protective scales and armor plates, known as scutes.
No Sweat Glands: They lack sweat glands, relying on evaporation and behavioral adaptations to regulate their body temperature.
Webbing: Some crocodile species have partially webbed feet, which aid in swimming and maneuvering in water.
Salt Glands: Crocodiles have specialized salt glands on or near their tongues that help them excrete excess salt and maintain their water balance.
Valves: They possess valves in their throats that allow them to breathe with their mouths open while submerged in water.
Nasal Passages: Crocodiles have valves that allow them to close their nostrils when submerged, preventing water from entering their lungs.
Third Eyelid: They possess a third eyelid, called the nictitating membrane, that helps protect their eyes both above and underwater.
Ear Openings: Crocodiles can seal their ear openings while underwater, shielding their inner ears from water pressure.
Low Metabolism: Crocodiles have a slow metabolic rate, which enables them to survive long periods without food.
Camouflage: Many crocodile species have cryptic coloration, blending with their surroundings and increasing their chances of successful ambush.
Sensory Organs: Crocodiles have special sensory organs, known as integumentary sense organs, distributed in their skin, making them sensitive to vibrations and pressure changes in the water.
