Kerala, known for its lush landscapes and rich biodiversity, is home to a fascinating array of lizard species. Whether you’re a nature enthusiast, a researcher, or a curious traveler, understanding the different types of lizards found in Kerala can enhance your appreciation of this region’s unique wildlife. This listicle provides detailed insights into the most common and intriguing lizard species in Kerala, highlighting their distinctive features, habitats, and why they are worth knowing about.
1. House Lizard (Hemidactylus frenatus)
The house lizard, also known as the common house gecko, is one of the most ubiquitous reptiles in Kerala. It easily adapts to urban and rural settings, often seen crawling on walls and ceilings at night. Recognizable by its small size, about 10-15 cm, and translucent skin, it plays a vital role in controlling insect populations, making it a beneficial presence in households.
2. Golden Day Gecko (Phelsuma madagascariensis)
While originally native to Madagascar, the golden day gecko has been introduced to Kerala’s gardens and urban spaces. It’s striking with its vibrant green body and bright red markings on the back and tail. Active during the day, this diurnal lizard is admired for its vivid coloration and agility, making it a favorite among reptile enthusiasts.
3. Indian Chameleon (Chamaeleo zeylanicus)
The Indian chameleon is endemic to the Indian subcontinent, including Kerala’s forests. It’s distinguished by its ability to change color, from green to brown or even yellow, depending on mood and temperature. Its zygodactylous feet and prehensile tail allow it to navigate trees and shrubs expertly, and its slow, deliberate movements make it a fascinating creature to observe.
4. Malabar Gliding Lizard (Draco dussumieri)
This remarkable lizard is endemic to the Western Ghats of Kerala. Known for its patagium—an extended flap of skin that acts like a parachute—it can glide between trees over considerable distances. Its elongated ribs support the gliding membrane, and its camouflage helps it blend into the forest canopy, making it a true master of the treetops.
5. Common Garden Lizard (Calotes versicolor)
The common garden lizard, or Indian garden lizard, is widespread across Kerala’s gardens, parks, and forests. It’s easily identified by its vibrant red throat pouch during the breeding season and its agile movements. Its ability to adapt to various habitats and its striking coloration during mating season make it a fascinating subject for wildlife watchers.
6. Flat-headed Rock Agama (Psammophilus platycephalus)
This species prefers rocky outcrops and dry areas in Kerala’s Western Ghats. It has a distinctive flattened head and a robust body, with males often displaying bright orange or red coloration during the breeding season. Its territorial behavior and basking habits make it a common sight in rocky terrains.
7. Indian Sand Lizard (Lacerta agilis)
Found in sandy and arid regions of Kerala, the Indian sand lizard is adapted to dry, open landscapes. It has a slender body, often with a brown or grey coloration that provides excellent camouflage. Its quick movements and preference for sunbathing make it a common sight in the region’s sandy patches and dry fields.
8. Banded Ground Gecko (Cyrtodactylus sp.)
Kerala hosts several species of banded ground geckos, characterized by their banded patterns and ground-dwelling habits. These geckos are nocturnal and often found under rocks or leaf litter. Their cryptic coloration and secretive lifestyle make them a challenging yet rewarding species for herpetologists to observe.
9. Flying Dragon (Draco volans)
Another gliding marvel of Kerala’s forests, the flying dragon has extended ribs supporting its gliding membrane and a throat flap called a dewlaps. It spends most of its time perched on trees, blending with the foliage. Its ability to glide helps it escape predators and move efficiently through the forest canopy, making it an extraordinary sight for nature lovers.
10. Indian Leaf-toed Gecko (Hemidactylus platyurus)
This gecko is named for its leaf-shaped toes, which aid in climbing smooth surfaces. It’s commonly found in Kerala’s homes and temples, often hiding in crevices. Its small size, silent movement, and unique toe pads make it an interesting species for those studying gecko adaptations.
How to Choose
When selecting a lizard to observe or keep as a pet, consider factors such as habitat preferences, activity patterns (diurnal or nocturnal), and size. It’s essential to respect their natural behavior and environment. If you’re interested in conservation, focus on species endemic to Kerala like the Malabar Gliding Lizard or Indian Chameleon, which are crucial for local biodiversity. Proper identification helps in understanding their needs and ensuring ethical interactions.
