The Andaman Sea is world-famous for its turquoise waters, white sandy beaches, and thriving marine life. But beyond the ocean and coral reefs lies a fascinating world that many visitors overlook — the reptiles that call these tropical islands home.
Whether you’re joining the best Andaman Sea tours in Thailand, exploring hidden beaches, or hopping from island to island, you might encounter these cold-blooded residents without even realizing it. These creatures play a vital role in the island ecosystem — and spotting them offers a glimpse into the rich biodiversity beyond the shoreline.

🏝️ Why Do the Andaman Islands Have So Many Reptiles?
Island ecosystems like those in the Andaman Sea create the perfect environment for reptiles to thrive:
✅ Fewer large predators compared to the mainland
✅ Warm, humid climate — ideal for cold-blooded animals
✅ Abundant food sources like insects, small animals, and plants
From remote jungle interiors to rocky beaches, reptiles have adapted to life on these islands, becoming essential members of the ecosystem.
🦎 Reptiles You Might See on the Andaman Islands
1. Oriental Garden Lizard (Calotes versicolor)
Also known as the “changeable lizard” or “tree dragon,” these small lizards are common across the islands. During mating season, males often develop bright red or orange heads — making them surprisingly photogenic!
2. Tokay Gecko (Gekko gecko)
Famous for their loud, distinct “To-kay!” calls at night, these large, colorful geckos often live on bungalow walls or in forested areas. Despite their bold appearance, they help control insects naturally.
3. Skinks
These sleek, shiny lizards move quickly and can often be seen darting across rocks or paths. Their glossy bodies sometimes make them look almost snake-like at first glance.
4. Monitor Lizards (Varanus salvator)
The giants of the reptile world, monitor lizards can grow over 2 meters long. While more commonly seen on the mainland, some larger Andaman islands — especially those with forest or mangrove areas — provide suitable habitat.
🌿 Why Reptiles Matter to Island Ecosystems
Reptiles may not be as flashy as tropical fish or coral reefs, but they play a crucial role in maintaining ecological balance:
✅ Natural pest control — reducing mosquito and insect populations
✅ Part of the island food chain — as both predator and prey
✅ Seed dispersal and soil health contribution by some species
✅ Indicators of healthy, undisturbed island environments
Seeing reptiles during your eco friendly island tours is a sign that the island’s ecosystem is functioning well — above and below the waves.
