Information:  - The abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The region occupied by the abdomen is termed the abdominal cavity. In arthropods it is the posterior tagma of the body; it follows the thorax or cephalothorax. The abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between L5 and S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear.  - Japyx is a genus of diplurans belonging to the family Japygidae . These eyeless , predatory hexapods largely shun direct sunlight , remaining under stones and among detritus , where they use pincer - like cerci to catch their tiny prey .  - Earwigs make up the insect order Dermaptera and are found on all continents except Antarctica. With about 2,000 species in 12 families, they are one of the smaller insect orders. Earwigs have characteristic cerci, a pair of forceps-like pincers on their abdomen, and membranous wings folded underneath short forewings, hence the scientific order name, "skin wings". Some groups are tiny parasites on mammals and lack the typical pincers. Earwigs rarely use their flying ability.  - The japygids (family Japygidae) are a taxon of hexapods, of the order Diplura. In this family, the paired cerci at the end of their abdomens are pincer-like (superficially similar to the unrelated earwigs) and are used to catch their tiny prey. Seventy genera are recognised, divided among seven subfamilies.  - The order Diplura is one of the four groups of hexapods, alongside insects, springtails and Protura. They are sometimes called "two-pronged bristletails". Around 800 species have been described, of which around 70 occur in North America, 12 in Great Britain and two in Australia.
