The coelacanth first evolved almost 400 million years ago. It gets its name from two Latin words mille (meaning thousand) and pes (meaning foot). Scientific Name: Polyxenus spp. Despite the common name, no millipede has been discovered with 1,000 legs: common species have between 34 and 400 legs, and the record is held by Illacme plenipes, with individuals possessing up to 750 legs – more than any other creature on Earth. The scientific study of millipedes is known as diplopodology, and a scientist who studies them is called a diplopodologist. Common names include American giant millipede, worm millipede, and iron worm. The scientific study of millipedes is known as diplopodology, and a scientist who studies them is called a diplopodologist. The legs of an individual are generally rather similar to each other, although often longer in males than females, and males of some species may have a reduced or enlarged first pair of legs.  They are generally black or brown in colour, although there are a few brightly coloured species, and some have aposematic colouring to warn that they are toxic. Many of these mites are believed to be phoretic rather than parasitic, which means that they use the millipede host as a means of dispersal. The chilognaths are in turn divided into two infraclasses: the Pentazonia, containing relatively short-bodied groups such as pill millipedes, and the Helminthomorpha ("worm-like" millipedes), which contains the vast majority of species, with long, many-segmented bodies. The longest extant species is the giant African millipede (Archispirostreptus gigas). They have a generally elongated body form but are not at all worm-like as are other millipedes found in Colorado. A millipede is one of the most interesting creatures. Range. Bears sleep through winter, but are there other animals that hibernate? The order Scolopendrida, or Scolopendromorpha, of the tropics contains the largest centipedes, with Scolopendra gigantea of the American tropics reaching a length of 280 mm (11 inches). Despite its name, it has about 100 legs. Continue Reading.

Moody has decided to give the animal a scientific name … #10 Hibernating Animal: Ground Squirrel Unlike tree squirrels, many ground squirrels are all about burrowing. Some secretions discolor the … Height. It is an important recycler of nutrients, feeding on decaying matter.  Several living orders also appear in the fossil record. Millipedes can be unwanted especially in greenhouses where they can cause severe damage to emergent seedlings. The terms "segment" or "body ring" are often used interchangeably to refer to both haplo- and diplosegments.  A 2011 summary of millipede family diversity by William A. Shear placed the order Siphoniulida within the larger group Nematophora.. Some species moult within specially prepared chambers of soil or silk, and may also shelter in these during wet weather, and most species eat the discarded exoskeleton after moulting. An Even Bigger Millipede? , Millipede bodies may be flattened or cylindrical, and are composed of numerous metameric segments, each with an exoskeleton consisting of four chitinous plates: a single plate above (the tergite), one at each side (pleurites), and a plate on the underside (sternite) where the legs attach.  Both groups of myriapods share similarities, such as long, multi-segmented bodies, many legs, a single pair of antennae, and the presence of postanntennal organs, but have many differences and distinct evolutionary histories, as the most recent common ancestor of centipedes and millipedes lived around 450 to 475 million years ago in the Silurian. The general scientific name that identifies Millipedes is Diplopoda. Also known simply as the Chocolate Millipede, this species shares much of its characteristics in common with the other two, but typically has a lighter brown color, similar in appearance to chocolate (thus the name).  Because they can't close their permanently open spiracles and most species lack a waxy cuticle, millipedes are susceptible to water loss and with a few exceptions must spend most of their time in moist or humid environments. Image Credit: Leann T.S. Class Diplopoda de Blainville in Gervais, 1844, Millipedes are among the first animals to have colonised land during the Silurian period. As oxygen levels lowered through time, arthropods became smaller. , Millipedes occur on all continents except Antarctica, and occupy almost all terrestrial habitats, ranging as far north as the Arctic Circle in Iceland, Norway, and Central Russia, and as far south as Santa Cruz Province, Argentina. Diet . , Due to their lack of speed and their inability to bite or sting, millipedes' primary defence mechanism is to curl into a tight coil – protecting their delicate legs inside an armoured exoskeleton.  Several invertebrates have specialised behaviours or structures to feed on millipedes, including larval glowworm beetles, Probolomyrmex ants, chlamydephorid slugs, and predaceous dung beetles of the genera Sceliages and Deltochilum.  This was a period when the science of diplopodology flourished: rates of species descriptions were on average the highest in history, sometimes exceeding 300 per year. , Many millipede species have commensal relationships with mites of the orders Mesostigmata and Astigmata. During heavy rains and the fall season, they will migrate from their normal habitat and will often find their way into homes or offices. In some groups, the gonopods are kept retracted within the body; in others they project forward parallel to the body.  Paranota may allow millipedes to wedge more securely into crevices, protect the legs, or make the millipede more difficult for predators to swallow. Scientists who study millipedes are called diplopodologists, and the scientific study (like astronomy or biology) of millipedes is known as diplopodology. There are two major groups of millipedes whose members are all extinct: the Archipolypoda ("ancient, many-legged ones") which contain the oldest known terrestrial animals, and Arthropleuridea, which contain the largest known land invertebrates.  Other vernacular names include "thousand-legger" or simply "diplopod". , The bristly millipedes (order Polyxenida) lack both an armoured exoskeleton and odiferous glands, and instead are covered in numerous bristles that in at least one species, Polyxenus fasciculatus, detach and entangle ants. All other millipedes belong to the subclass Chilognatha consisting of two infraclasses: Pentazonia, containing the short-bodied pill millipedes, and Helminthomorpha (worm-like millipedes), containing the great majority of the species.. In its natural habitat it can be found in more savanna type environments rather than only dense forests. The earliest known land creature, Pneumodesmus newmani, was a 1 cm (0.4 in) long archipolypodan that lived 428 million years ago in the upper Silurian, and has clear evidence of spiracles (breathing holes) attesting to its air-breathing habits. Scientific Name. First appearing in the Silurian period, millipedes are some of the oldest known land animals. Similar Images . Their function is unknown, but they also occur in some centipedes, and are possibly used to measure humidity or light levels in the surrounding environment. A millipede is one of the most interesting creatures. The Apheloria virginiensis is a millipede that has no widely accepted common name, yet is fairly common in the northeastern and mid-Atlantic U.S., and Ontario in Canada. Has an uncanny knack for problem-solving! Not Evaluated. , In 1971, the Dutch biologist C. A. W. Jeekel published a comprehensive listing of all known millipede genera and families described between 1758 and 1957 in his Nomenclator Generum et Familiarum Diplopodorum, a work credited as launching the "modern era" of millipede taxonomy. Scientific Names of Common Centipede Species Researcher claims that there is an estimated amount of 8,000 centipede species around the world and there are only 3,000 of these species that has been named and described.  During copulation in most millipedes, the male positions his seventh segment in front of the female's third segment, and may insert his gonopods to extrude the vulvae before bending his body to deposit sperm onto his gonopods and reinserting the "charged" gonopods into the female.  The science of millipede biology and taxonomy is called diplopodology: the study of diplopods.  Some of these substances are caustic and can burn the exoskeleton of ants and other insect predators, and the skin and eyes of larger predators. Each diplosegment bears two pairs of legs, rather than just one as in centipedes. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures. Detailing the physical features, habits, territorial reach and other identifying qualities of the Crested Millipede. Millipedes inhabit areas under rocks, in the leaf litter, in rotting logs and occasionally in burrows which are all known as micro-habitats. Despite its name, it only has about 40 legs. Scientific name: Polydesmus angustus Found in compost heaps and under stones in gardens, the Flat-backed millipede is a common minibeast.  In biology, some authors have advocated millipedes as model organisms for the study of arthropod physiology and the developmental processes controlling the number and shape of body segments. African Giant Millipede . Flat-backed millipedes in the order Polydesmida tend to insert their front end, like a wedge, into a horizontal crevice, and then widen the crack by pushing upwards with their legs, the paranota in this instance constituting the main lifting surface. However, despite their name, these creatures do not have thousands of legs. The bowfin is a primitive fish that first evolved in the Jurassic. , Millipedes appear in folklore and traditional medicine around the world. First aid consists of flushing the area thoroughly with water; further treatment is aimed at relieving the local effects. This millipede, recognized by its distinct semi-flattened … (diplous), "double" and ????? The millipede is from the same family as the centipede, but the millipede generally has more legs for its body length than the centipede. (Chilopoda Scolopendromorpha: Scolopendridae). It gets its name from two Latin words mille (meaning thousand) and pes (meaning foot).  Some species commonly sold or kept include species of Archispirostreptus, Aphistogoniulus, Narceus, and Orthoporus. These factors have favoured genetic isolation and rapid speciation, producing many lineages with restricted ranges. The millipede is a medium to large sized invertebrate that is found under rocks and in decaying logs all around the world. , Millipede eyes consist of several simple flat-lensed ocelli arranged in a group or patch on each side of the head.  This is called millipede burn. Millipedes are Myriapods, which means they have long segmented bodies, short heads and many pairs of legs, their numerous legs being their most obvious feature. Millipede sperm lack flagella, a unique trait among myriapods. Millipede Scientific Classification Kingdom: Animalia Phylum: Arthropoda Order: Diplopoda Scientific Name: Diplopoda.  Millipedes, centipedes, and other terrestrial arthropods attained very large sizes in comparison to modern species in the oxygen-rich environments of the Devonian and Carboniferous periods, and some could grow larger than one metre. Found in compost heaps and under stones in gardens, the Flat-backed millipede is a common minibeast.  Some species can survive freshwater floods and live submerged underwater for up to 11 months. Add to Likebox #135889138 - Millipede on a branch in Taman Negara National Park, Malaysia. There are about 12,000 species of millipedes. Although the name "millipede" derives from the Latin for "thousand feet", no known species has 1,000; the record of 750 legs belongs to Illacme plenipes.  Eye exposures to these secretions causes general irritation and potentially more severe effects such as conjunctivitis and keratitis. Many species deposit the eggs on moist soil or organic detritus, but some construct nests lined with dried faeces, and may protect the eggs within silk cocoons. Most millipedes are slow-moving detritivores, eating decaying leaves and other dead plant matter. In the female, the genital pores open into paired small sacs called cyphopods or vulvae, which are covered by small hood-like lids, and are used to store the sperm after copulation.  Few species of millipede are at all widespread; they have very poor dispersal abilities, depending as they do on terrestrial locomotion and humid habitats. However, despite their name, these creatures do not have thousands of legs. Millipedes Scientific Name: Diplopoda Millipedes make their home in damp places outdoors under mulch, piles of dead leaves, rocks, or wood. The remaining segments, from the fifth to the posterior, are properly known as diplosegments or double segments, formed by the fusion of two embryonic segments. Common Name: Centipede, millipede Scientific Name: Varies Order: Chilopoda and Diplopoda Description: Centipedes can easily be distinguished from millipedes by counting the number of pairs of legs arising from most body segments: millipedes have two pairs, while centipedes bear one pair per segment, with the first pair of legs being modified into fangs. , Millipedes breathe through two pairs of spiracles located ventrally on each segment near the base of the legs. Etymology and names. The scientific name of this animal is Diplopoda.  In certain Himalayan Bhotiya tribes, dry millipede smoke is used to treat haemorrhoids. They thrive in areas where soil continuously stays damp. Desert Millipede. Other habitats include coniferous forests, caves, and alpine ecosystems. Estimates of the true number of species on earth range from 15,000 to as high as 80,000. Cricket’s legs rub together to make noise and that was the easiest way for me to identify it.  The gonopods develop gradually from walking legs through successive moults until reproductive maturity. The science of millipede biology and taxonomy is called diplopodology: the study of diplopods. The digestive tract is a simple tube with two pairs of salivary glands to help digest the food. Approximately 12,000 millipede species have been described.  In Zambia, smashed millipede pulp is used to treat wounds, and the Bafia people of Cameroon use millipede juice to treat earache. The excretory organs are two pairs of malpighian tubules, located near the mid-part of the gut. If you need expert professional advice, contact your local extension office. Black and shiny in colour, these Millipedes have a long cylindrical shape and are multi-segmented. Its scientific name is Ophistreptus guineensis. When the millipede feels that it is in danger it curls up into a spiral and some species of millipede even release a disgusting smelling liquid that deters many of the animals that prey on the millipede. The term "millipede" is widespread in popular and scientific literature, but among North American scientists, the term "milliped" (without the terminal e) is also used.Other vernacular names include "thou… , Millipedes are preyed on by a wide range of animals, including various reptiles, amphibians, birds, mammals, and insects. Millipedes inhabit areas under rocks, in the leaf litter, in rotting logs and occasionally in burrows which are all known as micro-habitats. Millipedes can be distinguished from the somewhat similar but only distantly related centipedes (class Chilopoda), which move rapidly, are venomous, carnivorous, and have only a single pair of legs on each body segment. In some millipedes, the last few segments may be legless.  A large subfamily of assassin bugs, the Ectrichodiinae with over 600 species, has specialized in preying upon millipedes. Millipedes are also known to eat some species of plants (that are alive) and the larger species of millipede also hunt insects. In addition to the 16 living orders, there are 9 extinct orders and one superfamily known only from fossils. Among myriapods, millipedes have traditionally been considered most closely related to the tiny pauropods, although some molecular studies challenge this relationship. Ready? , The first segment behind the head is legless and known as a collum (from the Latin for neck or collar). And today, we’re counting them down.  The head alone exemplifies the differences; millipedes have short, elbowed antennae for probing the substrate, a pair of robust mandibles and a single pair of maxillae fused into a lip; centipedes have long, threadlike antennae, a pair of small mandibles, two pairs of maxillae and a pair of large poison claws.  The most conspicuous leg modifications are involved in reproduction, discussed below. , The young hatch after a few weeks, and typically have only three pairs of legs, followed by up to four legless segments. (Ed.)  The basal subclass Penicillata contains a single order, Polyxenida (bristle millipedes). , A novel interaction between millipedes and mosses was described in 2011, in which individuals of the newly discovered Psammodesmus bryophorus was found to have up to ten species living on its dorsal surface, in what may provide camouflage for the millipede and increased dispersal for the mosses.. The term "millipede" is widespread in popular and scientific literature, but among North American scientists, the term "milliped" (without the terminal e) is also used. This may be because they are too small to have enough leverage to burrow, or because they are too large to make the effort worthwhile, or in some cases because they move relatively fast (for a millipede) and are active predators.
