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.




Dr. Marisa Tellez

Executive Director & Co-Founder

“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 and her husband created the Crocodile Research Coalition (CRC) to further promote crocodile research and community involvement to assist in the conservation of crocodilians and their habitat.


Karl Kohlman


Karl Kohlman grew up hunting and fishing on the gulf coast in Southeast Texas. He went on to the University of Texas at Dallas to receive a BA in Arts and Technology, leading him to a career in visual effects for film in Los Angeles. He spent 6 years working on summer blockbusters like Oblivion, TRON, Enders Game, Transformers 2, and many more. He spent a great deal of time outdoors surfing and hiking, trying to find balance with the long hours spent inside working, but was unable to do so. He moved to Seattle in hopes of finding a better equilibrium, working in video games on Halo 5, surrounded by a much more lush environment.

After only a year, his wife Marisa proposed that they move to Belize for at least a year for her work. In no time at all, they sold off their stuff, packed up what was left and moved to the Jewel of the Caribbean.

Over the next 6 months, working as a research assistant for his wife, Karl fell in love with the plethora of wildlife surrounding him and the crocodilians that they were researching. Seeing the positive difference he and his wife were already making among the local communities through their outreach and research, he and his wife Marisa decided to start the Crocodile Research Coalition, in hopes of learning more about the crocodiles and their environment, while educating locals and tourists alike about these incredible creatures and their importance to the surrounding environment.



Gliselle Marin

Research Coordinator

Gliselle Marin was born and raised in Ladyville, Belize before moving to Belize City in her last year of high school. Her early interest in natural sciences and the environment led her to obtain an Associates Degree in Biology from St. John’s College Junior College. She received a BSc. in Wildlife and Wildlands Management from Purdue University in Indiana, U.S.A. where she was a member of the Williams Herpetology Laboratory. There she worked as a field and laboratory technician for 2 years, studying woodland salamanders, timber rattlesnakes, and eastern hellbenders. She then worked as a Research Coordinator for Texas Christian University on a project with Nextera Energy on the effects of wind turbine operations on bat and bird mortality in Meunster, Texas. Her passion for research continued later in the Manu National Forest of Peru, where she spent 6 months as a research assistant for the Manu Bird Project, a joint long-term study with the University of California, Davis, the University of British Columbia and the University of Florida. She returned to Belize for a few years to gain some practical job experience before applying for graduate studies. She recently completed a Master of Conservation Biology from Victoria University of Wellington in New Zealand where her thesis focues on the survivorship of the endemic Hihi (stitchbird) within a translocated population. Gliselle hopes to bring her research experience to Belize to provide vital scientific information on native species than can serve to inform better management and policy for Belizean wildlife.

Jonathan Triminio

Orange Walk Representative

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.

Helen Sung

Research Associate

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

Research Associate

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.
