The Bengal monitor (Varanus bengalensis), also called Indian monitor, is a species of monitor lizard distributed widely in the Indian subcontinent and parts of Southeast Asia and West Asia. The populations of monitors in India and Sri Lanka differ in the scalation from those of Myanmar; these populations were once considered subspecies of the Bengal monitor, but are now considered two species within the V. bengalensis species complex. What was once the nominate subspecies, V. bengalensis, is found west of Myanmar, while the clouded monitor (V. nebulosus) is found to the east. Clouded monitors can be differentiated by the presence of a series of enlarged scales in the supraocular region. The number of ventral scales varies, decreasing from 108 in the west to 75 in the east (Java).
The Bengal monitor can reach 175 cm (69 in) with a snout-to-vent length (SVL) of 75 cm (30 in) and a tail of 100 cm (39 in). Males are generally larger than females.

The belly is white, banded with dark... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Bengal Monitor is recorded against all the reptiles logged in Bandipur National Park (8 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
