4. Living Rock: Pyura chilensis (Chile and Peru)
Sometimes referred to as a ‘living rock’ , Pyura chilensis is a tunicate that resembles a mass of organs inside a rock. It is often found in dense aggregations in the intertidal and subtidal coast of Chile and Peru. It is the closest anyone can get to finding blood in a stone! It is also served as a local delicacy in the cities surrounding the coasts.
