Polychrus gutturosus, also known as Berthold's bush anole or monkey tailed anole, is a species of lizard found in tropical Central and South America. It is sometimes referred to as a "forest iguana". It lives in forests and jungles from Honduras to Ecuador. It can reach up to 70 cm (2.3 ft) in total length, including its very long tail, and males are considerably smaller than females. This insectivorous lizard is a climbing species that can often be seen holding onto branches. It can even hold on with its hind legs, though it moves slowly that way.
Genus Polychrus is often classified in the family, Polychrotidae, but some prefer to treat it as a subfamily, Polychrotinae, under the family Iguanidae. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Berthold's Bush Anole is recorded against all the reptiles logged in Tenorio Volcano National Park (7 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.
