Project Overviews: HAB Toxins in Sharks and Rays

HBOI Foundation

Lead PI: Matthew Ajemian

The Indian River Lagoon is home to 17 different species of sharks and rays. These animals play a key role in estuarine food webs and are indicators of both environmental and human health. This project aims to evaluate the exposure of two common species, bull sharks and spotted eagle rays, to HAB toxins in the Indian River Lagoon during bloom and non-bloom events. Because these species represent different trophic levels, researchers are also learning more about how toxins are transferred up the food chain.
