Octopus invasion on Welsh beach blamed on effects of recent storms

Brett Jones, who runs SeaMôr dolphin-watching boat trips, said he first witnessed the phenomenon when he was returning from a sunset trip.

Mr Stones said he helped collect those that were completely out of the water and returned them to the sea. I've never seen anything like it before. "There were probably about 20 or 25 (octopuses) on the beach".

"It sounds like a fish kill event, which happens sometimes mostly in lakes and ponds that have really poor water quality", Elisa Caref, a marine biology educator, tells Jezebel.

A group of octopuses were seen walking along a Ceredigion beach on Friday night, surprising experienced sea-goers.

A rare incident of octopuses crawling ashore on a British beach has shocked everyone, and nobody can quite explain why it's happening.

Because the area was hit by two recent storm systems-the remnants of Ophelia and Brian-Wright suspects a link. On their Facebook page, SeaMor Wildlife Tours wrote on Saturday that they spotted "quite a few dead ones on the beach this morning".

James Wright, curator at the National Marine Aquarium in Plymouth, said he had heard one or two other accounts last week of some being found in the intertidal zone - where the tide comes in and out - along the North Devon and the Welsh coasts.

What the creatures do underwater is undoubtedly their business, but when they decide crawl on dry land to die, they're surely signalling something threatening - something to be anxious about.

Several wildlife experts quoted by the Telegraph and the BBC say this kind of behaviour by the usually solitary and territorial animals is very unusual. "It could simply be injuries sustained by the rough weather itself or there could be a sensitivity to a change in atmospheric pressure".

Hurricane Ophelia and storm Brian battered the Welsh coast earlier this month with gusts up to 80 miles per hour.
