- Footage shows the 8-legged creatures crawling across the sand in New Quay
- The curled octopuses are rarely seen and live up to 100 metres (330 feet) deep
- Strange behaviour has baffled scientists who say it could be linked to weather
- They may be coming out of the sea due to injuries sustained by the rough weather or sensitivity to a change in atmospheric pressure
- ‘It doesn’t fit with their breeding or foraging behaviour’, James Wright, curator at the National Marine Aquarium in Plymouth told MailOnline
More than 20 octopuses have been witnessed walking out of the sea on the Welsh coast.
The bizarre moment was caught on camera by staff at a local dolphin watching company who were left completely baffled.
Footage clearly shows the eight-legged creatures crawling across the sand in New Quay, Ceredigion.
Experts suspect it could be related to a change in atmospheric pressure caused by the recent storms, Ophelia and Brian.
But scientists say there is no clear evidence to explain why the octopuses would strand themselves on a beach.
Brett Jones, 39, owner of SeaMôr Dolphin Watching Boat Trips, was returning the boat after a sunset trip at 10pm on Friday when he first spotted them.
‘They were coming out of the water and crawling up the beach. We don’t quite know what’s causing it’, he said.
‘Perhaps it’s because the sea has been quite rough recently but I’ve never seen anything like it before. They were walking on the tips of their legs.
‘A friend of mine said it happened the night before and there was about 20 last night.’
While octopuses have been spotted playing with dolphins off the Mid Wales coast, this is the first time video footage has been captured by the company.
The curled octopuses, which are common in British waters, are normally rarely seen and live up to 100 metres (330 feet) deep.
‘There’s been a few online videos showing them coming out under the cover of darkness to hunt but to have them crawl out in the number that was seen on that particular night if quite unusual’, James Wright, curator at the National Marine Aquarium in Plymouth told MailOnline.
‘They’re crawling across the beach and not looking for prey in rock pools -so that’s out of character and doesn’t fit with their breeding or foraging behaviour’, he said.
Mr Wright said there had been sightings of octopuses coming out of the water along the North Devon coast and parts of Wales but not in this number.
Mr Jones is now encouraging people to quickly return the creatures to the water if they are spotted on the beach.
He said: ‘On Friday, we picked them up and dropped them in the water at the end of the pier.

‘If people are able to they should pick them up and put them back as they need to go back into the water very quickly.
‘A few dead ones were washed up on the beach on Saturday morning.’
The sea dwellers measure about 20 inches (50cm) in length and have been seen curled up on the sand.
‘But them even being found in the intertidal is not common and suggests there is something wrong with them I am afraid’, Mr Wright told the Telegraph.
‘As the areas where they are exhibiting this odd behaviour coincides with the two areas hit by the two recent low pressures depressions and associated storms of Ophelia and Brian, it could be supposed that these have affected them.

‘It could simply be injuries sustained by the rough weather itself or there could be a sensitivity to a change in atmospheric pressure.’
The curled octopus, also known as the lesser octopus, releases a dark fluid from its body when it feels threatened. This makes the water dark which disorientates its predators.
It’s body is yellow or red in colour with rusty brown patches and its skin is covered in wart-like bumps.
It feeds on crustaceans, molluscs and other invertebrates as well as fish.
