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]
House centipedes lay their eggs in spring. In a laboratory observation of 24 house centipedes, an average of 63 and a maximum of 151 eggs were laid. As with many other arthropods, the larvae look like miniature versions of the adult, albeit with fewer legs. Young centipedes have four pairs of legs when they are hatched.
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.
Scutigeridae is a family of centipedes that are known as house centipedes. It includes most species of house centipedes, including Scutigera coleoptrata and Allothereua maculata . [ 1 ] [ 2 ]
Thus, centipedes are most commonly found in high-humidity environments to avoid dehydration, [38] and are mostly nocturnal. [39] Centipedes live in many different habitats including in soil and leaf litter; they are found in environments as varied as tropical rain forests, [25] deserts, [40] and caves. [41]
During the Carboniferous Period, Earth's atmospheric oxygen levels surged, helping some plants and animals grow to gigantic proportions. One notable example was Arthropleura, the biggest bug ever ...
