The Gephyreus Project conducts photo-identification of Lahille’s bottlenose dolphins in Brazil, Uruguay, and Argentina, focusing on their movements and abundance. Notable findings include births, as well as sightings of whales and orcas.

In 2024, the Gephyreus Project and partners mapped the impacts of the historic flood in Rio Grande do Sul on Lahille’s bottlenose dolphins in Lagoa dos Patos, analyzing mortality, pollutant bioaccumulation, and conservation strategies.

The Gephyreus Project is organizing the “Marine Environmental Education and Training” course in Rio Grande (RS), addressing fishing, the coastal zone, and climate change to train local agents committed to environmental preservation.
