About Sawyer

The Story Behind the Name: When the researchers on the SRC boat came back to the baited lines, they discovered one had been dragged off into Timbuktu (figuratively speaking of course). As they pulled the line in, they came face-to-face with the feistiest Great Hammerhead yet. He had no desire to come onto the boat and made this message very clear. Once on board, this large mature male was donned the name Sawyer, after Captain Curt’s son. This little boy also makes his presence known, with his radiant laughter and smiles. Even at 1 year of age, Sawyer knows the ocean is a great place to enjoy (especially when he gets to help his dad steer the boat).

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