The turnip-tailed gecko (Thecadactylus rapicauda) is a species of gecko widely distributed from Mexico southward through Central America and into South America as far south as Brazil, and on many islands in the Lesser Antilles. It was long thought to be the only member of its genus, until T. solimoensis was described in 2007.
It is a large gecko, reaching a length of 120 mm snout-to-vent. Its color varies from pale to dark gray to deep orange. Individuals can also change color. It can vocalize a series of chirps, which it mainly does while active at night. Its name comes from its swollen tail, which is used to store fat. It also waves its tail as a sign of aggression, and can shed its tail to distract predators. They are nocturnal in nature and are frequently found 5–30 feet up the trunks of palm trees.
It is called tai-marɛɁa in the Kwaza language of Rondônia, Brazil. Predators of T. rapicauda include the phyllostomid bat, Chrotopterus auritus. Parasites of T. rapicauda include the malarial parasite Plasmodium aurulentum.

Possible
About 20% of wildlife watchers report a Turniptail Gecko sighting in Corcovado National Park on a given day, based on 37 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 41 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Turniptail Gecko in Corcovado National Park on a given day, against under 5% in September and October, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Turniptail Gecko sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
8th of 18
Of the 18 parks where we can rate Turniptail Gecko sightings, Corcovado National Park ranks 8th at about 20%. The best odds are in Main Ridge Forest Reserve (Trinidad and Tobago, about 60%), Brownsberg Nature Park (Suriname, about 60%) and Tayrona National Natural Park (Colombia, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Turniptail Gecko is recorded against all the reptiles logged in Corcovado National Park (37 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.
