Lizards are a diverse group of reptiles found around the world. In this guide, we explore some of the most iconic and fascinating lizard species, detailing their habitats, physical traits, and behaviors.
Argentine Black and White Tegu (Salvator merianae)
Native to northern and central Argentina, found in forests, wetlands, grasslands, and coasts. Dark body with white transverse spots forming tail rings. Omnivorous, oviparous, and ecologically beneficial. Active in warm months, hibernate in self-dug or reused burrows.
Red Tegu (Tupinambis rufescens)
Large-bodied, reddish coloration with irregular dark patterns. Found in dry regions of Argentina. Shy and fast when threatened. Both tegu species are commercially hunted for leather and are listed under CITES Appendix II.
Western Canary Lizard (Gallotia galloti)
Endemic to Tenerife and La Palma (Canary Islands). Males have blue facial patches that intensify during mating season; females lack these and are cryptically colored. Diet includes insects and plants.
Sand Lizard (Lacerta agilis)
Found across Europe and Central Asia in varied landscapes. Males turn green in the breeding season; females are brown. Endangered in parts of Spain.
European Green Lizard (Lacerta viridis)
Inhabits shrublands and forest edges in Europe and parts of Asia. Males are green with black spots; both sexes develop blue jaws in spring.
Western Green Lizard (Lacerta bilineata)
Formerly a subspecies of L. viridis, now recognized as a distinct species. Found in Europe and introduced to the U.S. Notably, its tail is longer than its body.
Komodo Dragon (Varanus komodoensis)
The world’s largest lizard, native to several Indonesian islands. Reaches up to 3 meters and 166 kg. Can consume 80% of its weight in a single meal. A top predator that uses venom-like compounds in its saliva to kill large prey.

A small species from Southeast Asia with elongated ribs and wing-like skin folds for gliding between trees. Feeds on insects and blends well with tree bark.
Desert Horned Lizard (Phrynosoma platyrhinos)
Found in northern Mexico and the southwestern USA. Covered in small spines with horn-like structures on the head. Lives in deserts, camouflages in sand to ambush prey and avoid predators.
