The jaw apparatus is by far the most conspicuous and complicated organ in Limnognathia maerski. Furthermore, it has been an important key to understand the phylogenetic position of Micrognathozoa in the Animal Kingdom. Despite the animals minute size the jaws are composed of fifteen independent elements. The sizes of the elements range from 4 Ám to 14 Ám (0,004 mm - 0,014 mm) and they are interconnected by muscles and ligaments. Even though the muscles are extremely small, they are still anatomically similar to the skeletal muscles in mammals and insects.
