A man thought he saw "an alien" while on a stroll along a popular Edinburgh beach - but it turned out to be a type of worm called a 'sea mouse'.
Mike Arnott, 33, was taking a stroll along Portobello Beach in east of the capital on Monday when the creature caught his eye.
He found a strange green fluorescent object on the sand while the tide was out. The engineer originally thought it was a moss-covered pinecone before realising it was alive.
