This is the heartbreaking moment a hermit crab was seen struggling along a beach, stuck inside a doll’s head. <br /><br />The fragile creature had been living inside the plastic toy which washed up on the shore of Wake Island in the western Pacific Ocean.<br /><br />Volunteer Joseph Cronk, who was on the island for an environmental project, was walking along the beach on May 10 collecting trash when he saw the crab.<br /><br />Joseph filmed the creature to show the devastating effects of plastic pollution and waste on marine creatures. However, removing it from its makeshift shell could have harmed it.<br /><br />He said: ''I see a lot of these crabs exchanging their shells for many things. Film canisters and soda cans are pretty common. But this one really gets the point across.''<br /><br />Wake Island is a coral atoll in the northeastern area of the Micronesia subregion, some 1,991 miles southeast of Tokyo and 1,501 miles east of Guam.<br /><br />Joseph visited the island in December last year and took part in a beach cleanup. But the rubbish had already covered the beach again by the time he returned on his most recent trip at the start of May.
