Cozumel, Quintana Roo – The Punta Sur Ecological Reserve in Cozumel recently hosted a scientific documentation session that could reshape Mexico’s understanding of crocodile biodiversity. An audiovisual report, produced by environmental reporter Patricio Medina and videographer Miguel Ángel Guillermo for Mongabay LATAM, focused on the “Laguna Colombia” area—home to a new crocodile species in Cozumel.
This effort is part of Mongabay LATAM’s international series “Expediciones Científicas,” which highlights significant ecological discoveries across Latin America and beyond. During the visit, the filmmakers were accompanied by Héctor González Cortés, deputy director of the Punta Sur Ecotourism Park and representative of the Cozumel Parks and Museums Foundation (FPMC). González Cortés facilitated access to the reserve and shared essential knowledge that enriched the filming process.
More than ten years of research
The expedition builds on more than ten years of research by Dr. José Ávila and Dr. Pierre Charruau, members of the Crocodile Specialist Group of the International Union for Conservation of Nature (IUCN). Their studies indicate that crocodiles inhabiting Cozumel and Banco Chinchorro display significant genetic, morphological, and ecological differences from known species. These findings suggest the potential recognition of two new crocodile species in Mexican waters.
If confirmed, this discovery would increase Mexico’s officially recognized crocodile species from three to five, positioning the country among the world’s most diverse in crocodile species.
During filming, crocodiles were observed in their natural habitat, providing crucial footage for scientific communication. The documentary also highlights the FPMC’s ongoing efforts in ecosystem conservation, habitat restoration, and environmental education—key to protecting Cozumel’s endemic and endangered species.
Juanita Alonso Marrufo, general director of the FPMC, noted that this collaboration aligns with the New Agreement for the Well-being and Development of Quintana Roo, promoted by Governor Mara Lezama Espinosa. The agreement emphasizes the safeguarding of the state’s natural heritage.
“Opening Punta Sur as a living laboratory reinforces our commitment to sharing scientific knowledge to raise environmental awareness and benefit the common good. This documentary is an opportunity to showcase Cozumel’s ecological importance and the work being done to preserve its biodiversity,” Alonso Marrufo said.
The Cozumel Parks and Museums Foundation continues to advance science, conservation, and sustainable development, positioning Cozumel as a model for balancing nature with human progress.
