A video captured by Taylor Bonachea shows an intense confrontation between two reptiles—an alligator and a crocodile—snapping, biting, and hissing at each other. Witnesses near the Shark Valley Observation Tower could be heard gasping as they watched the dramatic scene unfold. Bonachea believes the reptiles were fighting over a basking spot. Big Picture: According to the U.S. Geological Survey, South Florida is the only place in the world where the American crocodile and the American alligator coexist in the wild. Key Differences: Snout Shape: Alligators have a U-shaped snout, while crocodiles feature a more pointed, V-shaped one. Color: Alligators are typically black, whereas crocodiles are usually lighter in color, ranging from grayish to brownish hues.
