Phrynops geoffroanus, also commonly known as Geoffroy's side-necked turtle and Geoffroy's toadhead turtle, is a species of large side-necked turtle in the family Chelidae. The species is endemic to South America. The specific name, geoffroanus, is in honor of French naturalist Étienne Geoffroy Saint-Hilaire.
P. geoffroanus is found in southwestern Venezuela, southeastern Colombia, eastern Ecuador, and eastern Peru, southward and eastward through southwestern Brazil and northern Bolivia to Paraguay and northeastern Argentina, then northward through eastern Brazil. It also occurs in eastern Venezuela, and in adjacent Guyana.

With luck
About 10% of wildlife watchers report a Geoffroy’s Side-necked Turtle sighting in Brasilia on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 3rd most-seen of the 8 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.
February and April
In those months about 30% of wildlife watchers report a Geoffroy’s Side-necked Turtle in Brasilia on a given day, against under 5% in January, July and October–November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Geoffroy’s Side-necked Turtle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 12
Of the 12 cities where we can rate Geoffroy’s Side-necked Turtle sightings, Brasilia ranks 7th at about 10%. The best odds are in Recife (Brazil, about 40%), Goiânia (Brazil, about 30%) and João Pessoa (Brazil, about 20%).
GBIF citizen-science records
It is estimated from how often the Geoffroy’s Side-necked Turtle is recorded against all the reptiles logged in Brasilia (15 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.
