Habitat and environment

The Yangtze alligator calls the lush wetlands and marshes of the Yangtze River basin its home. Here, amidst the labyrinth of waterways and dense vegetation, it has adapted to thrive in a habitat teeming with life. The tranquil waters and abundant prey of its watery domain provide the perfect backdrop for the alligator's existence.

Physical traits and dietary habits

With its sleek, armored body and formidable jaws, the Yangtze alligator cuts a striking figure against the river's serene backdrop. Growing up to two meters long (6.6 ft), it boasts a distinctive olive-green hue that blends seamlessly with its surroundings. This apex predator preys upon fish, crustaceans, and small mammals, employing stealth and cunning to secure its next meal.
