Movement, Migration, and Reproductive Biology of Two Manta Species in Mexican Waters
Project Leader
Understanding where Mobulid rays, like oceanic mantas in Mexico, live is key to protecting them from overfishing, which has left them endangered. Misclassification has caused gaps in our knowledge, making reserves in critical spots like La Reina essential. Caribbean studies and population research highlight the need for habitat preservation and focused conservation efforts to ensure their survival.
Filling Knowledge Gaps on Manta Distribution and Biology
This project aims to deepen our understanding of Mobulid ray distribution, focusing on two manta species in Mexican waters. Recent taxonomic distinctions have revealed that much of the existing research has emphasized reef mantas, leaving significant knowledge gaps about oceanic mantas—especially in Mexico. Although interest in these species is increasing, key aspects such as their global distribution, movement patterns, and reproductive biology remain poorly understood.

He sits on scientific committees for marine reserves in Mexico and actively contributes to conservation policy.
A passionate communicator, Mauricio has given around 300 talks, advised international documentaries, and earned multiple awards for his work. He’s a member of Mexico’s National System of Researchers and has authored over 85 scientific publications, a book, and several conservation manuals.
Identifying Key Habitats and Conservation Priorities
Our research highlights important conservation zones in the Eastern Tropical Pacific, including La Reina, a potential nursery for juvenile Mobula birostris.
Movement studies suggest a metapopulation structure in the Mexican Pacific, pointing to the need for coordinated regional conservation strategies.
Additionally, understanding the genetic diversity and connectivity of Caribbean manta populations is critical for designing effective protections, such as marine reserves and seasonal fishing bans, to ensure the long-term survival of these endangered species.
