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 donors to be involved and participate in shark research to see how their donations are being used to study and protect sharks and our marine environment. We have found that these experiences completely transform the perceptions that individuals have about and towards sharks.

Fins Attached is a US based 501(c)(3) non-profit. All donations given by participants is used to support the research and conservation efforts of Fins Attached and their partners.
