This 4 cm critter can be found on many sites here in Lembeh. They make their fortress from coconut shells that sink down to the sea floor. Many people think they are not that special because they are so easily found. But many times, even the most common critters are fun if you read their story from their moves. Watch how they approach you or run away from you. If you are lucky, you will understand them as they try to communicate with you. Maybe they will cooperate and give you a good pose for you photos. They usually see you before you see them. They hide between the shells until you approach then they move away. They can carry their coconut shells, or in this case sea shells, as far as 22 meters. When they find a safe place, they will hide themselves inside the shells again. Approach them as slow as you can so as not to scare them.
