Our understanding of the shark and ray fauna in Andros is limited, particularly information on those that reside in the pelagic ecozone of the Tongue of the Ocean. Further Andros is vast, with unexplored creeks and back-country that likely provide key nursery areas for many species. Delineating and describing these habitats and learning more about the biology and behavior of the animals that use them will contribute important data to conservation efforts, especially for species whos populations have experienced substantial declines, such as the smalltooth sawfish, oceanic white-tip, scalloped and great hammerhead sharks. 

Our lead scientist, Dr. Tristan Guttridge has 12-years of experience conducting scientific research with sharks in the Bahamas, working as the director of the world famous Bimini Sharklab for 6 years. His is well versed in a variety of techniques, from biotelemetry (acoustic and satellite tracking), to catch and release (via longlines and polyball fishing), semi-captive behavioral experiments, SCUBA diving with photo ID and laserphotogrammetry and both baited and non-baited remote underwater video surveillance (RUVs and BRUVs). More recently, he has pioneered a research project investigating the biology and behavior of the elusive and endangered great hammerhead shark.

The opportunity to visit Andros and learn more about its secrets is a biologists dream, vast swatches of unchartered habitat, abundant seemingly healthy populations of sharks and rays, there's no limit to the possibilities! Our early expeditions will be an important learning ground for Tristan to get to know the study system, its inhabitants and develop key questions that will lead to an improved understanding of the biology, ecology and behavior of elasmobranch fishes.
