Overview

• PADI diver Jonathan Brennan filmed the 5ft shark and identified it as a porbeagle by its rounded, dark grey-brown dorsal fin and white-edged patch.
• The shark remained in waist-deep water about 30ft from shore for roughly 25 minutes before returning to deeper sea.
• Researchers believe the unusual proximity was driven by abundant prey, including squid, mackerel and a recent influx of Mediterranean octopus.
• The porbeagle is classified as vulnerable in the north-east Atlantic by the IUCN, reflecting ongoing conservation concerns.
• Experts note porbeagles are not typically aggressive toward humans and advise observers to maintain a safe distance.
