📖 1. Overview
The Northern Caiman Lizard is a lizard living along waterways in South American tropical forests, specialized for feeding on snails and clams.
🦴 2. Anatomy & Morphology
It has a green body and a reddish head, and the crocodile-like scales on its back give it its name. Its long, flattened tail acts as an oar when swimming, and a transparent third eyelid serves as goggles underwater.
🔍 3. Ecology & Behavior
It feeds mainly on snails and clams, crushing the shells with its powerful jaws, swallowing the meat, and spitting out the shell fragments. Females dig burrows in riverbanks to lay eggs and do not care for the young.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
