It also has relatively short antennae and legs compared to the Scutigeromorpha. This group, the most diverse at 1260 species, also contains the largest and leggiest specimens at 27 or more pairs of legs. Smaller centipedes are generally incapable of piercing human skin. Scutigerinidae, composed of three species in the genus Scutigerina, is restricted to southern Africa and Madagascar. 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. House Centipedes have an abundance of legs that are so close together, they are almost feathery. They are probably used for sensing vibrations, and may even provide a sense of hearing. [25] A 19th-century Tibetan poet warned his fellow Buddhists, "if you enjoy frightening others, you will be reborn as a centipede."[26]. [24], Even nonvenomous centipedes are considered frightening by some humans due to their dozens of legs moving at the same time and their tendency to dart swiftly out of the darkness towards one's feet. This clade contains the longest centipedes; the maximum number of thoracic segments may also vary intraspecifically, often on a geographical basis; in most cases, females bear more legs than males. Centipedes deal with water loss through a variety of adaptations. Family: Oryidae. The venomous bite of larger centipedes can induce anaphylactic shock in such people. The eyes have a fixed number of four ocelli on each side in the family Scolopendridae and one ocellus per side in the genus Mimops (family Mimopidae), but other families are blind. The group is the sole extant representative of the Notostigmomorpha, defined by having a single spiracle opening at the posterior of each dorsal plate. Scolopendra Scolopendra cingulata Scientific classification Kingdom: Animalia Phylum: Arthropoda Class: Chilopoda Order: Scolopendromorpha Family: Scolopendridae Genus: Scolopendra Linnaeus, 1758 Type species Scolopendra morsitans Linnaeus, 1758 Scolopendra is a species-rich genus of large tropical centipedes of the family Scolopendridae. Geophilomorphs lose water less rapidly than lithobiomorphs, though they have a greater surface area to volume ratio. Studies on their activity rhythms confirm this, although a few observations of centipedes active during the day have been made, and one species, Strigamia chinophila, is diurnal. Examination of centipede gut contents suggests that plant material is an unimportant part of their diets, although centipedes have been observed to eat vegetable matter when starved during laboratory experiments. The geophilomorph centipedes have variable segment numbers within species, yet as with all centipedes, they always have an odd number of pairs of legs. Scolopendra gigantea, also known as the Amazonian giant centipede, is the largest existing species of centipede in the world, reaching over 30 cm (12 in) in length. Being among the earliest terrestrial animals, centipedes were one of the first to fill a fundamental niche as ground level generalist predators in detrital food webs. Each one has light and dark banding on it. Time of development to reproductive period is highly variable within and among species. Little is known of the life history of the Craterostigmomorpha. In other cases, the males just leave them for the females to find. [4]:354–356, Centipede defences include their speed and venomous forcipules, as well as the secretion of defensive chemicals. Two families are included, the Henicopidae and Lithobiidae. Centipedes grow their legs at different points in their development. A few species of parthenogenetic centipedes are known. These limbs, or maxillipeds, end in sharp claws and include venom glands that help the animal to kill or paralyze its prey. They also bear long and multi-segmented antennae. Little is known about scutigeromorph or craterostigmomorph diets. Water loss is a result of centipedes lacking a waxy covering of their exoskeleton and excreting waste nitrogen as ammonia, which requires extra water. [6], As predators, centipedes mainly use their antennae to seek out their prey. [4], The Lithobiomorpha and Scutigeromorpha lay their eggs singly in holes in the soil, and the female fills the holes with soil and leaves them. Genus Eremochloa Büse – centipede grass P: Genus Eremopyrum (Ledeb.) The group includes at least seven families: Mecistocephalidae, Geophilidae (including the former Linotaeniidae, Dignathodontidae and Macronicophilidae), Oryidae, Himantariidae, Schendylidae (including the former Ballophilidae), Zelanophilidae, and Gonibregmatidae (including the former Neogeophilidae and Eriphantidae). This may be because geophilomorphs have a more heavily sclerotized pleural membrane. – mock bluestem P: Genus Eulalia Trin. [7], Behind the head, the body consists of 15 or more segments. Centipedes are predominantly generalist predators, which means they have adapted to eat a variety of different available prey. There is a single ocellus on each side of the head capsule. In addition, centipedes are relatively long-lived when compared to insects. The Editors of Encyclopaedia Britannica This article was most recently revised and updated by Adam Augustyn, Managing Editor, Reference Content. The Oryidae are a family of centipedes belonging to the order Geophilomorpha of the class Chilopoda . Small geophilomorphs attain highest densities, followed by small lithobiomorphs. 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. Males deposit a spermatophore for the female to take up. Their low diversity and intermediate position between the primitive anamorphic centipedes and the derived Epimorpha has led to them being likened to the platypus. [6] Accordingly, they are found in soil and leaf litter, under stones and dead wood, and inside logs. [4]:354–356 They form an important item of diet for many species and the staple diet of some such as the African ant Amblyopone pluto, which feeds solely on geophilomorph centipedes,[16] and the South African Cape black-headed snake Aparallactus capensis. Each one has light and dark banding on it. If disturbed, the female either abandons the eggs or eats them; abandoned eggs tend to fall prey to fungi rapidly. The body is covered with black and yellow mottling with a dark line running down the 'spine'. Females of the Geophilomorpha and Scolopendromorpha show far more parental care. They are eyeless and blind, and bear spiracles on all leg-bearing segments—in contrast to other groups, which usually bear them only on their 3rd, 5th, 8th, 10th, 12th, and 14th segments—a "mid-body break", accompanied by a change in tagmatic shape, occurring roughly at the interchange from odd to even segments. The first postcephalic appendage is modified to venom claws. Time of development of the embryo to hatching is highly variable and may take from one to a few months. The only 2 known amphibious centipedes, Scolopendra cataracta and Scolopendra paradoxa belong to this order.[14][15][33][34]. Said to have medicinal properties and to be reinvigorating,[22] the liquor with the centipede submerged in it is consumed as a special drink. Centipedes are among the largest terrestrial invertebrate predators, and often contribute significantly to the invertebrate predatory biomass in terrestrial ecosystems. Jaubert & Spach – false wheatgrass P: Genus Eriachne R. Br. All mature lithobiomorph centipedes have 15 leg-bearing segments.[4]:27. All centipedes are potential intraguild predators. It is known to eat lizards, frogs, birds, mice, and even bats, catching them in midflight,[8] as well as rodents and spiders. - Follow me Foodie, 10.1580/1080-6032(2001)012[0093:CE]2.0.CO;2, "Evolutionary developmental biology does not offer a significant challenge to the neo-Darwinian paradigm", Evolution of blindness in scolopendromorph centipedes (Chilopoda:Scolopendromorpha): insight from an expanded sampling ofmolecular data, "Conflict between datasets and phylogeny of centipedes: an analysis based on seven genes and morphology", "A taxonomic review of the centipede genus Scolopendra Linnaeus, 1758 (Scolopendromorpha, Scolopendridae) in mainland Southeast Asia, with description of a new species from Laos", Chilobase, a web resource for Chilopoda taxonomy, Arachnida (spiders, scorpions, ticks, mites), Symphyla (symphylans or garden centipedes), Malacostraca (woodlice, shrimps, crayfish, lobsters, crabs), Branchiopoda (fairy, tadpole, clam shrimps, water fleas),, Articles with dead external links from November 2018, Articles with permanently dead external links, Articles containing Ancient Greek (to 1453)-language text, Creative Commons Attribution-ShareAlike License, The upper three groups form the paraphyletic. Bites can be dangerous to small children and those with allergies to bee stings. Centipede reproduction does not involve copulation. In addition, the number and size of coxal pores may be variables affecting centipede water balance. Cavernicolous (cave-dwelling) and subterranean species may lack pigmentation, and many tropical scolopendromorphs have bright aposematic colors. Earthworms may provide the bulk of diets for geophilomorphs, since they burrow through the soil and earthworm bodies would be easily pierced by their venomous claws. Centipedes have a wide geographical range, even reaching beyond the Arctic Circle. In temperate areas, egg laying occurs in spring and summer, but in subtropical and tropical areas, little seasonality to centipede breeding is apparent. Geophilomorph centipedes have been used to argue for the developmental constraint of evolution; that the evolvability of a trait, the number of segments in the case of geophilomorph centipedes, was constrained by the mode of development.
