The marbled water monitor (Varanus marmoratus), also known commonly as the Philippine water monitor, is a large species of monitor lizard in the family Varanidae. The species is endemic to the Philippines. Varanus marmoratus can reach a total length (including tail) of 2 m (6.6 ft).
The marbled water monitor lizard is found on various islands of the noveleta, including Batanes Islands, Babuyan Islands, northern and central Luzon and Lubang Island. Varanus marmoratus is oviparous. The monitor lizard from Palawan, Mindoro, southern Luzon and the Sulu Archipelago was recently described as a new species, Varanus palawanensis.

No species of the same family or order lives in Manila, so these are its closest relatives here: other reptiles.
Possible
About 20% of wildlife watchers report a Marbled Water Monitor sighting in Manila on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 12 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
November and December
In those months about 30% of wildlife watchers report a Marbled Water Monitor in Manila on a given day, against under 5% in March–April and September, the lowest months. Those are among Manila's wettest months, with about 370 mm of rain a month against 100 mm in April.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Marbled Water Monitor sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Manila, in our data
Manila is the only city on Wallace's Line with enough records to rate Marbled Water Monitor sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Marbled Water Monitor is recorded against all the reptiles logged in Manila (17 verified sightings), 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.
