The Iguazú National Park documented the start of a new hatching season for tortoiseshell turtles (Phrynops williamsi) in the Cataratas area. This event, which repeats every summer, is a sign of the environmental value that the park protects and reinforces the importance of conservation efforts for this threatened species.
Park authorities requested extreme caution from visitors, especially on the path to the Devil’s Throat, one of the busiest sectors, to avoid harm to the newly hatched specimens.
A Priority Species for Conservation
The Phrynops williamsi is the only species of the Order Testudines included in the list of 22 prioritized reptiles for observation, recording, research, and monitoring in Iguazú National Park. Its restricted distribution and the threats it faces justify its inclusion in this special category within the National System of Protected Areas.
The Department of Conservation and Environmental Education maintains an updated database on the species and develops actions aimed at reducing the impact of public use, especially in high tourist traffic areas.
Documentation of Births
Park rangers and technicians recorded the hatching of neonates in the main nesting areas of the Cataratas area.
- The birth period occurs mainly in January and February, coinciding with the summer season and the highest flow of visitors.
- The most relevant sites are Puerto Tres Marías and the Water Intake, on the route to the Devil’s Throat.
- During dawn and dusk, the hatchlings emerge from their nests and begin their journey to the river.
Characteristics of the Tortoiseshell Turtle
- Appearance: oval, smooth shell, without ridges, brown to dark green with black spots.
- Size: medium, between 30 and 37 cm in length.
- Diet: primarily carnivorous, although it can behave as an omnivore.
- Habitat: streams and rivers surrounded by jungle, with clean and flowing water.
- Distribution: recognized in the province of Misiones, Argentina.
Ecological Importance
The tortoiseshell turtle plays a key role in aquatic ecosystems:
- Ecological indicator: its presence reflects the good conservation status of streams and native forests.
- Ecosystem balance: being carnivorous, it regulates populations of invertebrates and small organisms in watercourses.
The hatching of tortoiseshell turtles in Iguazú National Park is a reminder of the environmental and ecological value of this natural heritage. Protecting the species requires the collaboration of visitors and authorities, reinforcing the conservation of a vital indicator of the health of Misiones’ aquatic ecosystems.
