A diver in Pembrokeshire, Iestyn Morgan, captured footage of a giant lion's mane jellyfish measuring between 10 to 15 meters. This sighting marks the first of its kind for Morgan in Wales, as these jellyfish are typically found in colder Scottish waters. Morgan aims to raise awareness about marine threats through his recordings.
Marine biologist Dr. Cathy Lucas noted that while the jellyfish's sting is unpleasant, it is not life-threatening. Morgan has observed an increase in jellyfish sightings in Welsh waters, suggesting a trend of warm-water species becoming more prevalent.
This sighting highlights the changing marine ecosystem in Wales, with warm-water species like the lion's mane jellyfish becoming more common. Readers should monitor local marine life trends and consider the implications of climate change on biodiversity in their coastal areas.
