All sharks were fished for, caught, studied and released for research purposes under Florida permits held by Florida International University scientists.
Eager students and teachers from The Benjamin School joined R/V ANGARI crew and scientists from Florida International University (FIU) College of Arts, Sciences and Education on an exciting and informative Coastal Ocean Explorers: Sharks expedition. Participants deployed baited remote underwater video system (BRUVS) surveys and specialized drumlines for shark fishing to study and collect data on marine life in the Lake Worth Lagoon.
During the expedition, participants assembled, deployed, recovered and watched footage from two BRUVS surveys. The BRUVS consisted of a metal frame which housed a camera pointed towards a bait cage. On footage from the first of the two surveys, which was deployed south of the Palm Beach Inlet, students observed some crevalle jacks (Caranx hippos) swimming in view of the camera. The second survey, deployed near Blue Heron Bridge, recorded footage of a nurse shark (Ginglymostoma cirratum) investigating the bait cage.
The other research gear that participants deployed was drumlines, which are specifically designed for shark fishing. Over the course of the day, students deployed 20 drumlines and caught 3 nurse sharks! Each shark was secured to the stern of R/V ANGARI by the FIU scientists and then collaboratively worked up by the scientists and students. The first step in each workup was to measure the sharks’ precaudal length and stretched total length. The second nurse shark was the smallest at 6.0 ft, and the third shark was the largest at 7.4 ft. After measuring, students took tissue samples and tagged the sharks with National Oceanic and Atmospheric Administration Cooperative Shark Tagging Program (NOAA CSTP) identification tags. Finally, the sex of the sharks was determined by feeling for the presence of claspers, modified fin appendages found on the underside of male sharks. All three sharks lacked claspers and were determined to be female. The three successful shark workups, along with the two BRUVS deployments, culminated in a great day of hands-on research for The Benjamin School!
CHIEF SCIENTIST

Will Sample is a Ph.D. candidate in the Marine Community and Behavioral Ecology Lab at Florida International University. His current research uses both long-term historical datasets and newer methods, such as high-resolution accelerometry, to study the movement and behavioral ecology of juvenile bull sharks. He specifically focuses on the way these sharks may be transporting nutrients across habitat boundaries, how they may be optimizing their movements to save energy and what the long-term implications of different behaviors they specialize in may be. Will’s research in the Florida Everglades studying the ways sharks move through this crucial ecosystem is important for conservation and informing habitat restoration and management efforts. Will earned a B.S. in Liberal Arts and Sciences from Florida Atlantic University in 2018 and has lived all throughout Florida for most of his life, from Jacksonville to Jupiter to the Keys. He is passionate about community outreach and education, particularly regarding Florida’s natural habitats, and currently serves as lead scientist for ANGARI’s Palm Beach County based Coastal Ocean Explorers: Sharks program aboard R/V ANGARI.
