Reptiles

What Are Reptiles? Basic Facts and Definition

Reptiles are cold-blooded animals with scaly skin, lungs for breathing, and most lay eggs on land. They belong to a class called Reptilia, which includes snakes, lizards, turtles, and crocodiles.

Key Features That Make an Animal a Reptile

Unlike mammals or birds, reptiles rely on external heat sources, like the sun, to regulate their body temperature. Their tough, dry skin helps prevent water loss, making them well-suited to hot and dry environments, though they’re also found in forests, wetlands, and even urban areas.

How Many Reptile Species Are Found in India?

India is home to around 763 species of reptiles, making it one of the most reptile-rich countries in the world. Some notable examples include the spectacled cobra, famous for its hood; the mugger crocodile, which is widely distributed in Indian rivers and lakes; and the Indian star tortoise, known for the striking radiating pattern on its shell. The king cobra, the world’s longest venomous snake, is also found in Indian forests. The fan-throated lizard, found in the dry grasslands of peninsular India, displays a colourful throat flap to attract mates.

Why Reptiles Matter to Ecosystems

However, many of these reptiles face serious threats. Habitat loss due to deforestation, wetland drainage, and expanding agriculture has reduced their natural ranges. Roadkill, human-wildlife conflict, and illegal trade in reptile skins, meat, and pets further endanger their populations. Some species, like the gharial — a fish-eating crocodilian once found throughout northern India’s rivers — are now critically endangered and survive only in a few protected areas. Conservation programmes, such as those in the National Chambal Sanctuary, are helping, but more awareness and community involvement are needed. Reptiles may not always get the attention that mammals or birds do, but they are vital to ecosystems — controlling pests, balancing food webs, and even shaping the health of freshwater systems.
