How many part are there to an insects body?
The arthropod body plan has a great deal to do with how they are classified. Insects are hexapods with three body sections, a head, consollidated thorax with three leg pairs, and an abdomen. The chelicerates, like arachnids, have two main body sections and eight legs. Myriapods have up to hundreds of sections each with a leg pair. Many crustaceans are decapods, have ten legs, often a fused cephalothorax and articulated abdominal segments like lobsters, crayfish, shrimp, prawns and krill; similar is true of crabs except the short abdomen (tail) is folded up beneath the thorax. Trilobites (now extinct) are named for having three longitudinal lobes.
