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.

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.
3rd of 18
Of the 18 parks where we can rate Turniptail Gecko sightings, Tayrona National Natural Park ranks 3rd at about 40%. The best odds are in Main Ridge Forest Reserve (Trinidad and Tobago, about 60%) and Brownsberg Nature Park (Suriname, about 60%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Turniptail Gecko is recorded against all the reptiles logged in Tayrona National Natural Park (44 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.
