About Cash

The Story Behind the Name: A very special and thoughtful grandmother, Bonnie Wheaton, decided to adopt a shark for her grandson’s birthday present. The birthday boy, Will Wanzenberg, decided to call his shark Cash, and tells us that he has a “huge appetite, is very active and intelligent, and loves to explore the marine world.”

We greatly appreciated their donation, and look forward to seeing the exciting tracks that Cash sends to us via his new satellite tag. If you also would like to adopt a shark, please visit our Adopt a Shark page.

Satellite Tagging: Cash was carefully tagged with the latest in satellite tag technology providing us with one of the first opportunities to follow the long term movements of these threatened species. He has already explored both the bay and reef sides of the Keys. Please keep checking back frequently to follow Cash’s movements, which will be updated every few days as his satellite tag continues to send us real-time tracking data.

Adopt-a-Shark: For information on how you can contribute to our shark conservation research by adopting and tracking your own shark, please visit our Adopt a Shark page.
