Symphyla

Symphyla are small, pale, soil-dwelling myriapods with elongated bodies, long antennae, and numerous leg-bearing segments. They lack eyes and breathe through a pair of spiracles on the head.

Myriapoda: Myriapoda is the arthropod subphylum containing centipedes, millipedes, pauropods, and symphylans. Symphyla is one of the four living myriapod lineages.
Euasymphyla: Euasymphyla is the symphylan group that includes the familiar garden symphylan, Scutigerella immaculata. This group contains the best-known species associated with crop-root damage.
Soil ecosystem: A soil ecosystem is the community of organisms and environmental conditions interacting within soil. Symphylans are small consumers within this diverse underground community.
Hans G. Bronn: Hans G. Bronn was a German zoologist and paleontologist who named the group Symphyla in the nineteenth century. Bronn established the name used for this myriapod class.
Arthropod: Arthropods are invertebrates with jointed limbs, segmented bodies, and an external skeleton. Symphylans share the defining body plan of arthropods.
Scutigerella immaculata: Scutigerella immaculata is a small symphylan found in cultivated soils and known to feed on plant roots. Its feeding habits illustrate how symphylans can affect seedlings and crops.
Soil food web: A soil food web is the network of feeding relationships among organisms living in soil. Symphylans feed on root tissues and fungi and are potential prey for soil predators.
Arthropod phylogeny: Arthropod phylogeny is the study of evolutionary relationships among arthropod lineages. The precise placement of Symphyla among other myriapods has been examined using morphology and molecular data.
Chilopoda: Chilopoda is the myriapod class of centipedes, typically bearing one pair of legs per body segment. Centipedes are a familiar myriapod contrast, with conspicuous eyes and prey-capturing legs.
Ecdysis: Ecdysis is the shedding of an arthropod's old exoskeleton as it grows. Symphylans molt repeatedly, adding body segments and legs during development.
