Overview
- RNLI lifeguards red-flagged St Ouen's Bay on Saturday after a lifeguard and other witnesses reported a dark grey animal about 10–12 ft long roughly 40 metres from shore.
- Rescuers evacuated swimmers and used a jet ski to sweep the bay, keeping the beach closed for about 45 minutes before finding no further sign and reopening the area.
- No injuries were reported and the species seen at St Ouen's Bay has not been identified in official statements.
- The sighting follows a nearby incident at Grève d'Azette earlier in the week when British Divers Marine Life Rescue confirmed a stranded smalltooth sand tiger shark that later died.
- Experts quoted in coverage say warmer sea temperatures have been linked to some sharks moving north, a pattern researchers now want to monitor to understand risks and conservation needs.
