Siphonophorida
Siphonophorida (Greek language, Greek for "tube bearer") is an order of millipedes containing two families and over 100 species. Description Millipedes in the order Siphonophorida are long and worm-like, reaching up to in length and up to 190 body segments. Eyes are absent, and in many species the head is elongated into a long beak, with mandibles highly reduced. The beak may serve in a suctorial function. The body has a dense covering of fine setae. Each body segment consists of a dorsal tergite, two lateral pleurites, and ventral sternite, which are unfused. The male reproductive appendages (gonopod (millipede), gonopods) are simple and leg-like, consisting of the ninth and 10th leg pairs. This lack of specialization has led to Siphonophorida being called a "taxonomist's nightmare", and C.A.W. Jeekel, Jeekel (cited in) jokingly gave the order the "taxonomists' award for least popular group among diplopods". Distribution Siphonophorida occurs from southwestern USA to Brazil a ...

Illacme Plenipes
''Illacme plenipes'' is a Siphonorhinidae, siphonorhinid millipede found in the Central California, central region of the U.S. state of California. It has up to 750 legs. One of two known species in the genus ''Illacme'', it was first seen in 1926, but was not rediscovered until 2005, almost 80 years after its discovery, by Paul Marek, then a Ph.D. student at East Carolina University. Description On average, ''I. plenipes'' have over 600 legs, twice the average for millipede species, with one recorded specimen having 750 legs. It had the most legs of any species known until ''Eumillipes persephone'' was described in 2021, which had 1306 legs. It is relatively small-bodied among millipedes. Females grow to just over 3 cm; males are slightly smaller and have fewer legs.

Millipedes
Millipedes are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from the Latin for "thousand feet", no species was known to have 1,000 or more until the discovery of '' Eumillipes persephone'', which can have over 1,300 legs. 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. Most millipedes are slow-moving detritivores, eating decaying leaves and other dead plant matter. Some eat fungi o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gonopod (millipede)
Gonopods are specialized appendages of various arthropods used in reproduction or egg-laying. In males, they facilitate the transfer of sperm from male to female during mating, and thus are a type of intromittent organ. In crustaceans and millipedes, gonopods are modified walking or swimming legs. Gonopods may be highly decorated with elaborate structures which may play roles in sperm competition, and can be used to differentiate and identify closely related species. Gonopods generally occur in one or more pairs, as opposed to the single (un-paired) reproductive organs such as the aedeagus of insects or the penis of harvestmen. Insects In insects, gonopods are appendages of the genital segment that may be used in insemination, or that comprise the egg-laying apparatus. Crustaceans In male decapod crustaceans, gonopods are modified swimming appendages (pleopods). The anterior two pair of pleopods in males are modified for sperm transferring, with differing degree of morphologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burmese Amber
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected. Geological context, depositional environment and age The amber is found within the Hukawng Basin, a large Cretaceous-Cenozoic sedimentary basin within northern Myanmar. The s ...

Pleurite
A sclerite (Greek , ', meaning "hard") is a hardened body part. In various branches of biology the term is applied to various structures, but not as a rule to vertebrate anatomical features such as bones and teeth. Instead it refers most commonly to the hardened parts of arthropod exoskeletons and the internal spicules of invertebrates such as certain sponges and soft corals. In paleontology, a scleritome is the complete set of sclerites of an organism, often all that is known from fossil invertebrates. Sclerites in combination Sclerites may occur practically isolated in an organism, such as the sting of a cone shell. Also, they can be more or less scattered, such as tufts of defensive sharp, mineralised bristles as in many marine Polychaetes. Or, they can occur as structured, but unconnected or loosely connected arrays, such as the mineral "teeth" in the radula of many Mollusca, the valves of Chitons, the beak of Cephalopod, or the articulated exoskeletons of Arthropoda.
