The South American snapping turtle (Chelydra acutirostris) is a species of turtle in the family Chelydridae. This species, which is endemic to Central and northwestern South America, was previously considered a subspecies of C. serpentina. Its restricted range in South America reflects its recent arrival there as part of the Great American Interchange.
Chelydra acutirostris is found in Honduras, Nicaragua, Costa Rica, Panama, Colombia, Ecuador, and Peru. No subspecies of C. acutirostris are recognized. On July 9 2026, the South American snapping turtle was evaluated as Near Threatened and its populations are starting to be decreasing by the IUCN Red List. Wikipedia →

GBIF citizen-science records
It is estimated from how often the South American Snapping Turtle is recorded against all the reptiles logged in Piedras Blancas National Park (8 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.
