Symphylans are small pseudocentipedes in the phylum Arthropoda and the subphylum [[Myriapoda]]. Though they resemble centipedes, they are much smaller ranging in size from 2 to 30 millimeters, and are translucent in color [1]. Symphyla have two body regions, a head and a segmented trunk, containing 12 segments with one pair of legs in each on the trunk which allow them to move rapidly throughout the [[soil]], and segmented antennae on the head [1].

Symphylans also have a postantennal organ on their head region, similar to [[collembola]], and 3 mouth parts [1]. | Symphylans are small pseudocentipedes in the phylum Arthropoda and the subphylum [[Myriapoda]].
