About Siorcan

The Story Behind the Name: Siorcan is a powerful Great Hammerhead shark adopted by Amelia Karenina Balonek and Faquiry Diaz. These two lucky individuals joined the SRC team out in the field in the spring of 2011 for a corporate trip. After seeing our work first hand, they gathered together to pledge their support for sharks by adopting their own shark. The name Siorcan comes from the Gaelic work for shark, ‘Siorc.’

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