📖 1. Overview

The Common Spiny-tailed Iguana is a large, sturdy lizard living in colonies around stone walls, rocky slopes, and forest borders in dry, open terrain.

🦴 2. Anatomy & Morphology

Adult males have a body about 18 inches (46 cm) long with a similarly long tail. Predominantly black, often with black bands on the back, males develop a prominent dorsal crest and a small dewlap.

🔍 3. Ecology & Behavior

Generally herbivorous, feeding especially on legume fruits, it also eats rodents, bats, frogs, small birds, and insects. Juveniles eat insects before shifting to an herbivorous diet as they grow; colonies have a strict dominance hierarchy, and these iguanas can run on their two hind legs.
