Fancy a unique holiday gift idea? Martin Graf of Shark Diver has made the unique suggestion of sponsoring a great white shark (Carcharodon carcharias) as a gift. The Marine Conservation Science Institute is seeking sponsors to help fund its photo ID database of the sharks at Guadalupe and its extensive research into their migration behavior.

By naming, or sponsoring a shark, you are helping to keep this research going. Shark #153 above is looking for sponsorship and a catchier title! (Image by Martin Graf/ Shark Diver).
