tongue worm  
Any of various small, colorless, tongue-shaped, wormlike invertebrates of the group Pentastoma, which is considered by many zoologists to be a phylum intermediate in evolutionary development between the annelids and arthropods. Tongue worms are parasites that live embedded in the respiratory systems of vertebrates, especially reptiles and also humans, in tropical regions. They have simple nervous and digestive systems but lack circulatory and respiratory systems. Also called pentastome.
