About Arianna

The Story Behind the Name: This lucky Great Hammerhead shark is part of the Adopt-a-Shark program, sponsored by marine enthusiast and entrepreneur Greg Markham. To share his passion for the ocean and sharks, Greg brought his friend Whitney McDaniel aboard an Islamorada shark tagging trip in May. She was so inspired by the experience that she claims to be ‘hooked on sharks’ now, learning more and more everyday. To celebrate the beautiful free spirit of this Great Hammerhead, she named the shark Arianna, after her exuberant young daughter. Although Arianna the girl and Arianna the shark may differ in the way of favorite foods (mac & cheese ”“vs”“ snapper), they both share a kindred spirit and utter excitement for life’s adventures.

Satellite Tagging: Arianna was carefully tagged with the latest in satellite tag technology providing us with the first opportunity to follow the long term movements of these threatened species. Please keep checking back frequently to follow Arianna’s movements, which will be updated every few days as her satellite tag continues to send us real-time tracking data.
