About Hurley

The Story Behind the Name: During a day of large swells on the high sea, several volunteers from South Broward High School as well as a few SRC intern veterans spent a considerable amount of time leaning overboard, sharing their lunches with the sharks. Perhaps it was the extra “chum” in the water, but whatever the reason, the crewmembers pulled aboard the largest Great Hammerhead yet. In playful memory of a day mostly spent hurling over the side of the boat, the young student volunteers decided to name this shark “Hurley.” He entered back into the water in excellent condition.

**Special Note** As you can see on the map, Hurley transmitted strong signals nearly every day for three months, until a few days after the Gulf Oil Spill began. Dr. Hammerschlag speculates that “the tag could have failed or it could have headed off somewhere else into deep water and just not come up in the last few months. But that’s very unlike the shark’s characteristics.” For more on SRC research on the Gulf Oil Spill, please check out this article on CNN (http://www.cnn.com/2010/US/06/28/oil.spill.sharks/?hpt=Sbin).

Satellite Tagging: Hurley 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 Hurley’s movements, which will be updated every few days as his satellite tag continues to send us real-time tracking data.
