About Prahyad

The Story Behind the Name: Prahyad is the adoptive shark of Jon Oh.

“The name means “to save/conserve” in Thai. The recent CITES announcement in Bangkok to protect some key species of sharks and manta rays is a welcome change of events for this species.”

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