A man thought he saw "an alien" while on a stroll along a Scottish beach - but it turned out to be a type of worm called a 'sea mouse'.<br />Mike Arnott, 33, was taking a stroll along his local beach, Portobello Beach, Edinburgh, yesterday when the creature caught his eye.<br />He found a strange green fluorescent object on the sand while the tide was out.<br />The engineer originally thought it was a moss-covered pinecone before realising it was alive.<br />Pete Haskell, of the Scottish Wildlife Trust, offered his expertise to help identify the alien-like animal.<br />He said it's a washed up 'sea mouse' - which is confusingly a type of WORM.<br />Pete said: "It looks a bit strange being out of the water, but it’s a type of marine bristle worm that’s found all around the UK coast.”<br />The lesser-known creature's iridescent shimmering green and gold bristles make it look unlike any other marine animal.<br />SWSYalien - by Amy Reast
