Varanus bengalensis, commonly known as the Bengal monitor or Indian monitor, is a large lizard belonging to the family Varanidae. This species is widely distributed across the Indian subcontinent and Southeast Asia, thriving in various habitats, including forests, grasslands, and urban areas. Adult Bengal monitors typically reach lengths of 3 to 5 feet, although some individuals can grow even larger. They are characterized by their elongated bodies, strong limbs, and a distinctive, long, forked tongue used for sensing the environment.

The coloration of Varanus bengalensis varies from light brown to dark gray, often featuring yellow or white spots and bands that help with camouflage in their natural surroundings. This species is primarily terrestrial but is also an adept climber and swimmer, allowing it to hunt a diverse diet of insects, small mammals, birds, and even carrion.

Bengal monitors are diurnal, displaying active behavior during the day, and exhibit a range of social interactions, including territorial displays. They are oviparous, laying clutches of eggs in sandy or soft substrates. Their adaptability to different environments and opportunistic feeding habits contribute to their status as an important predator in their ecosystems, as well as their popularity in the exotic pet trade.
