Centipede
Centipedes (from New Latin , "hundred", and Latin , " foot") are predatory arthropods belonging to the class Chilopoda (Ancient Greek , ''kheilos'', lip, and New Latin suffix , "foot", describing the forcipules) of the subphylum Myriapoda, an arthropod group which includes millipedes and other multi-legged animals. Centipedes are elongated segmented ( metameric) creatures with one pair of legs per body segment. All centipedes are venomous and can inflict painful bites, injecting their venom through pincer-like appendages known as forcipules. Despite the name, centipedes can have a varying number of legs, ranging from 30 to 382. Centipedes always have an odd number of pairs of legs; no centipede has exactly 100. Like spiders and scorpions, centipedes are predominantly carnivorous. Their size ranges from a few millimetres in the smaller lithobiomorphs and geophilomorphs to about in the largest scolopendromorphs. Centipedes can be found in a wide variety of environmen ...

Lithobiomorpha
The centipedes or Chilopoda are divided into the following orders. Scutigeromorpha The Scutigeromorpha are anamorphic, reaching 15 leg-bearing segments in length. Also known as house centipedes, they are very fast creatures, and able to withstand falling at great speed: they reach up to 15 body lengths per second when dropped, surviving the fall. They are the only centipede group to retain their original compound eyes, within which a crystalline layer analogous to that seen in chelicerates and insects can be observed. They also bear long and multi-segmented antennae. Adaptation to a burrowing lifestyle has led to the degeneration of compound eyes in other orders; this feature is of great use in phylogenetic analysis. The group is the sole extant representative of the Notostigmophora, defined by having a single spiracle opening at the posterior of each dorsal plate. The more derived groups bear a plurality of spiracular openings on their sides, and are termed the Pleurostigmo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scolopendridae
Scolopendridae (or, in older documents, Scolopendridæ) is a family of large centipedes (class Chilopoda). Nearly all species in this family have four ocelli (simple eyes) on each side of the head and only 21 pairs of legs, but there are exceptions: two scolopendrid species feature more legs (''Scolopendropsis bahiensis'', with 21 or 23 leg pairs, and ''S. duplicata'', with 39 or 43 leg pairs), and some scolopendrid species are eyeless and blind (e.g., ''Cormocephalus sagmus'', ''C. pyropygus'', and ''C. delta''). Three Asian members of this family, '' Scolopendra cataracta'', '' Scolopendra paradoxa'', and '' Scolopendra alcyona,'' are known to show amphibious behaviour. Two other species, '' Scolopendra hardwickei'' and '' Hemiscolopendra marginata,'' are known to show sexual dimorphism in the composition of their venom.

Geophilidae
The Geophilidae are a polyphyletic, cosmopolitan family of soil centipedes in the superfamily Geophiloidea containing the mostly defunct clades Aphilodontidae, Dignathodontidae, Linotaeniidae, Chilenophilinae, and Macronicophilidae. Species in this family are characterized by mandibles with a single pectinate lamella, slender antennae, sternal pores with variable arrangement, a generally slightly or moderately elongate head, frequently undivided coxosternite with two paramedian sclerotized lines, claws without rows of filament, and female gonopods usually being an undivided lamina. Compared to most other families in the suborder Adesmata, this family features a modest number of leg-bearing segments (no more than 125) and limited variation in this number within each species. Two species in this family include centipedes with only 29 pairs of legs: ''Geophilus persephones'' (29 pairs in the only specimen, a male), and '' G. richardi'' (29 or 31 pairs in the males and 33 pairs ...

Placodesmata
Mecistocephalidae are a monophyletic family of centipedes in the order Geophilomorpha. It is the only family in the suborder Placodesmata. Most species in this family live in tropical or subtropical regions, but some occur in temperate regions. This family is the third most diverse in the order Geophiliomorpha (after Geophilidae and Schendylidae), with about 170 species, including about 130 species in the genus ''Mecistocephalus''. This family differs from all other geophilomorphs insofar as the number of segments in mecistocephalids is generally fixed within each species and the same for each sex. The family includes centipedes with odd numbers of leg-bearing segments ranging from as few as 41 to as many as 101. A majority of the species in the genus ''Mecistocephalus'' have 49 pairs of legs, a majority so large that most species in the family Mecistocephalidae have 49 leg pairs, even though only one mecistocephalid species (''Proterotaiwanella sculptulata'') outside the genus '' ...

Pleurostigmomorpha is a subclass of centipedes, containing all the orders except Scutigeromorpha The centipedes or Chilopoda are divided into the following orders. Scutigeromorpha The Scutigeromorpha are anamorphic, reaching 15 leg-bearing segments in length. Also known as house centipedes, they are very fast creatures, and able to withstand .... It contains 4 orders, which are subsequently divided into 15 families, 363 genera, and 3104 species. The spiricales are always branched and present in pairs in Pleurostigmomorpha, as opposed to those of Notostigmomorpha, whose spiracles are shorter and appear individually.
