Help us help our beloved sharks and mantas by contributing id images to the official databases for Guadalupe white sharks and Socorro giant mantas. Your contribution of good quality identification images are essential to monitoring and further study of these populations. You CAN make a difference!!

We enthusiastically support conservation, scientific research, film making and educational efforts around Guadalupe and Socorro Islands. In 2005 we founded the 501C3 registered Socorro Conservation Fund and 2 years later founded the 501C3 Guadalupe Conservation Fund. Are you interested in getting involved? Please share the love and email Captain Mike at .

What We're Doing

Identified 170 (and counting!) individual sharks at Guadalupe Island with the help of Nicole Nasby, marine biologist.

Raised over $300,000 between generous donations from our guests and financial support from Captain Mike for research, surveillance, tracking & equipment.

Developed and implemented ID program using our boat’s satellite system. Photos are uploaded and shared with our researchers in real time.
