A man found something similar to an alien on a British beach

A dog walker in Wales came across thousands of white-shelled creatures clinging to a tree trunk thrown by water in Gwynedd, North-West Wales.

It turned out that the mysterious creatures were actually goose-neck shells, a culinary delicacy that can cost about 80 pounds per kilogram, according to NorthWalesLive.

Dave McGirr was on vacation when he was so amazed by what he saw that, being a keen photographer, he immediately started taking pictures.

He then looked it up on Google and was stunned when a search revealed that seashells were in high demand.

Dave said:

"I found out that these are Gooseneck shells, described as rare sea creatures similar to aliens. They say it's a delicacy that sells for more than 80 pounds per kilogram."
