Pacific Whale Foundation’s PacWhale Eco-Adventures will launch its “Finders Free” program on Sunday in celebration of World Whale Day.

The new program encourages PacWhale Eco-Adventures ecotour passengers to exchange high-resolution whale fluke photos for a complimentary future excursion. Pacific Whale Foundation researchers collect images of whale flukes, the underside of a humpback whale tail, to document resights of previously identified and cataloged whales.

If the image matches an individual already logged into the foundation’s Humpback Whale Photo-ID catalog, participants will receive a complimentary PacWhale ecotour within four to six weeks of receipt of submission.
