About CRC
Crocodile Research Coalition
The Crocodile Research Coalition (CRC) is a Belize-based nonprofit, established in January 2016, that seeks to preserve crocodiles and their environments throughout Central America and the Caribbean to ensure the long-term sustainability of biodiversity in the region. We believe the success of our conservation efforts parallels the involvement and support from local communities, thus we are continuously working alongside with local communities and partner organizations to empower people with the knowledge of co-existence and sustainable practices to ensure the survival of crocodiles and well-being of the communities that live beside them. Our outreach also incorporates working with the local and national governments, utilizing our research to better inform policy decisions regarding wildlife and their habitat (= translational ecology).
Although crocodiles are our flagship species in pursuing regional conservation efforts, the CRC recognizes that the conservation success of crocodiles is not only dependent on direct conservation efforts of the focal species, but also understanding how crocodiles interact with its environment and other wildlife as thriving and long-lasting conservation management is dependent on preserving the integrity of ecological interactions. Thus, through our research center in southern Belize, we facilitate research projects investigating crocodiles, as well as the surrounding flora and fauna.
The CRC is currently accruing further funding to build a state-of-the-art research facility on the Placencia Peninsula, however we do have the space and lodging to accommodate interested researchers and small academic groups nationally and internationally who wish to pursue wildlife and conservation research.
Founder
Dr. Marisa Tellez - Executive Director
“If a woman loves a crocodile, she takes on its character.” — Ancient Egyptian Proverb
At an age when most girls were playing with dolls, Dr. Marisa Tellez was developing knowledge of the world’s top predators as she knew at a young age she wanted to be an advocate and leader in the conservation of the world’s apex predators, particularly crocodiles. Books, television, and local wildlife facilities were the only outlets for her to “experience” crocodiles given she was growing up in the suburbs of Los Angeles, California. After receiving a BA in Cultural Anthropology and a BS in Zoology from the University of California, Santa Barbara in 2005, Marisa finally got her hands-on experience with crocodilians at the Eco-station in Culver City, California, and soon after began working at the Los Angeles Zoo. It was working at the zoo that she realized she wanted to head back to school and truly pursue scientific research with crocodilians, particularly investigating their interaction with parasites.
Marisa received a Master’s (2010) and PhD (2014) from the University of California, Los Angeles studying the interaction between parasites and crocodilians, publishing a book and various scientific publications. Her work, knowledge and passion for crocodile conservation was quickly acknowledged by the International Union for Conservation of Nature/Species Survival Commission-Crocodile Specialist Group (CSG), and was soon initiated into the CSG, as well as appointed as the Vice Regional Chair of Latin America for the CSG for her fieldwork in Guatemala, Mexico and Belize which began in 2008.
After receiving a National Science Foundation Postdoctoral Fellowship through the United States government to research the health and biodiversity of crocodilian habitat in Belize, Marisa soon called Belize home. Observing the difference her research and outreach was making in the local communities, Marisa co-founded the Crocodile Research Coalition (CRC) to further promote crocodile research and community involvement to assist in the conservation of crocodilians and their habitat.

Jonathan Triminio was born in Chetumal City, Mexico on April 16th, 1996. He grew up in the small town of Orange Walk “Shuga City” in northern Belize where he became fond of the great outdoors. As a young boy Jonathan enjoyed being outside observing his backyard’s wildlife and appreciating his natural environment. In 2013 he went on to pursue an Associate’s Degree in Natural Resource Management at Muffles Junior College. His relationship with nature grew as he started getting more involved in outdoor activities such as hiking, snorkeling and fishing all over Belize. Jonathan decided to continue his education and attended the University of Belize where he earned a Bachelor’s Degree in Natural Resource Management in 2019. In the midst of his Bachelor’s career Jonathan developed a genuine interest in crocodilian science and conservation so he based most of his academic work on crocodiles.
As part of his Bachelor’s Program, Jonathan had the great honor to carry out his Internship with the Crocodile Research Coalition which significantly helped him further his career in wildlife conservation. Since then Jonathan has volunteered his time and has been heavily involved in research and outreach with the CRC. As part of his Bachelor’s Program, Jonathan had the great honor to carry out his Internship with the Crocodile Research Coalition in the summer of 2018, which significantly helped him further his career in wildlife conservation. Jonathan continued to volunteer his time with the CRC as a Community Researcher being heavily involved in research and outreach with the CRC until officially joining the CRC team in January 2020.

I honestly never thought I would be working with crocodiles, let alone falling in love with working with them. Yet here I am, still working with crocodiles in Belize, but now as a 2019 NSF-GRFP funded Ph.D. student at the University of Hawaii at Manoa working as a research associate and colleague alongside Marisa and the CRC. Although Marisa fostered my start in parasitology, she encouraged me to make my own path and to ask my own questions. Currently, my research goal is to understand hybridization in two species of Central American crocodiles (Crocodylus acutus andC. moreletii) from both a genetic and phenotypic perspective. Using a genome-wide association study, I am investigating genetic markers from physiological stress in hybrid zones, for which I aim to use this research to promote effective conservation/management strategies in Belize alongside with the goals of the CRC, as well as fill in knowledge gaps in crocodilian biology and evolution.

Flavio Morrissiey has been working with crocodilian since 1989. He got his start at Gatorland in Orlando, Florida where he worked there for 17 Years. During that time he had developed behavioral management techniques for reptiles, specifically crocodilians. After leaving Gatorland as the General Curator he continued to assist over 30 facilities in Zoo Management. Co-creator of CrocFest, Flavio has volunteered his time for 10 years to bring people together for fundraising in crocodile conservation. CrocFest has raised nearly $500,000 for Crocodile researchers all over the world. He continues to develop techniques to find solutions to conservation problems with on going Human Crocodile Conflicts. Dr. Marisa Tellez has encouraged such ideas and with the Crocodile Research Coalition these ideas and techniques are being put to the test.
Recently the techniques have been applied to American Crocodiles and Morelets Crocodiles in Belize. Using negative reinforcement and aversive stimuli. In the case studies thus far the program seems to work with problematic crocodiles that pose a threat to human populations. At the same time these techniques are designed to teach crocodiles to avoid humans and their dangerous motives as well.

Dr. Xochitl Clare, a Marine Biologist and Theater Artist with Belizean and Jamaican heritage, brings a unique blend of skills to the CRC. As a Washington Research Foundation Fellow at the University of Washington, she's using her background in ecophysiology and storytelling to investigate the impacts of pollution and climate change on our coastal communities. Dr. Clare’s work focuses on one of our ecosystem’s key invertebrates, sea cucumbers, “earthworms of the sea”, that cycle nutrients in marine environments. While serving as a fishery species, sea cucumbers are also crucial for the health of our crocodile habitats.
Dr. Clare shares, "It's always been a dream to connect my culture and roots in Belize to my ocean science work. Pollution is an international challenge, impacting waters everywhere." Her work on sea cucumbers bridges the Pacific Northwest, USA, and Belize, Central America, already sparking international conversations on ocean solutions through community relationships.
Dr. Clare's time as a researcher and storyteller with the CRC, will allow us to further engage in local academic research with partners from the University of Belize and ensure our community is informed about anthropogenic impacts on our ocean resources.
