Abstract
Phylum Myriapoda consists of 13 000 species divided into four classes: Chilopoda (centipedes), Diplopoda (millipedes), Symphyla (garden centipede, pseudocentipede), and Pauropoda (millipede?like arthropods). There are two fat bodies of myriapods: one surrounds the midgut and regional viscera and is called the perivisceral fat body, and the other is immediately below the epidermis and is called the parietal fat body. Myriapods use a tracheal system for gas exchange, except for pauropods, which lack tracheae likely due to their small size. The primary immune effector cell in myriapods, similar to other arthropods, is the hemocyte. Myriapods require a humid environment due to the permeability of their cuticle which is not waterproof and lacks the lipid/wax characteristics of spiders and insects. Mechano? and chemoreceptors present have a similar histologic structure to those reported in insects.
