Indian water monitor has a muscular body covered in tough, rough scales with a prominent neck, long tail, and sharp claws. They come in different shades of brown, grey, or black, and have yellow bands or spots on their body. They are known for their exceptional strength and can weigh up to 20 kg, making them one of the heaviest lizards in India. They can run at a speed of 25 km/hr and swim with great ease, thanks to their long, flattened tail, which helps them propel in the water.

Habitat details

Indian water monitors are widely distributed across the Indian subcontinent and can be found in various habitats, including forests, grasslands, wetlands, and coastal regions. They prefer areas close to water bodies, such as lakes, rivers, and marshes, as they need to stay hydrated.

How they hunt and food habits

Indian water monitors are carnivorous and hunt a variety of prey, including fish, birds, small mammals, and insects. They are opportunistic feeders and have been known to scavenge on carrion as well. Their hunting patterns vary depending on the prey they are after. They often lie in wait for their prey to come to them or actively hunt them down.

Importance to ecosystem

Indian water monitors play a crucial role in maintaining the ecological balance of their habitat. As top predators, they help control the population of small mammals and insects, which, if left unchecked, can cause significant damage to the ecosystem. They are also an important food source for larger predators such as crocodiles and birds of prey.

IUCN status

Indian water monitors are listed as “Least Concern” on the International Union for Conservation of Nature (IUCN) Red List. While their population is not under immediate threat, habitat loss and fragmentation, hunting, and poaching for their skin and meat are some of the significant threats they face.


Indian water monitors are fascinating creatures with unique features that make them stand out from other lizards. They are widely distributed across India and play a crucial role in maintaining the ecological balance of their habitat. While they are not under immediate threat, conservation efforts are necessary to ensure their long-term survival.
