Symphylans, also known as garden centipedes or pseudocentipedes, are soil-dwelling arthropods of the class Symphyla in the subphylum Myriapoda. Symphylans resemble centipedes, but are very small, non-venomous, and may or may not form a clade with centipedes. [1] [2] More than 200 species are known worldwide. [3]
The centipedes like to hide in wood, beneath stones and rocks, in soil, and under small buildings. They are most common in gardens, in dead or rotting wood, beneath stones and rocks, and under sheds. They may be seen in basements in winter, though this is uncommon.
Myriapodology is the scientific study of myriapods which includes centipedes and millipedes. The field of myriapodology can also cover other myriapods such as pauropods and symphylans . Those who study myriapods are myriapodologists.
Myriapods have a single pair of antennae and, in most cases, simple eyes. Exceptions are the two classes symphylans and pauropods, and the millipede order Polydesmida and the centipede order Geophilomorpha, which are all eyeless. [10] The house centipedes on the other hand, have large and well-developed compound eyes. [11]
Tömösváry organ (arrow) on the head of a symphylan, just behind the base of an antenna. Tömösváry organs, also known as temporal organs or postantennal organs [1] are specialized paired sensory organs found in certain groups of myriapods (e.g. centipedes and millipedes) and hexapods (e.g. springtails), located on the head near the base of the antennae.

Scutigera is a centipede genus in the scutigeromorph (house centipede) family Scutigeridae, a group of centipedes with long limbs and true compound eyes (which were once thought to be secondary, re-evolved "pseudofacetted eyes" [1]).
The stalked eyes - like a crab's - are striking because no living members of the group of arthropods that includes millipedes and centipedes - called myriapods - have this kind of eye.
