Fins Attached



Citizen Science Research Expeditions

Fins Attached conducts research expeditions throughout the year. Some of these trips are open to donors of Fins Attached. The expeditions allow participants to witness and in some cases, participate in the research. We have found that these experiences completely transform the perceptions that individuals have about and towards sharks.
