Mammamia
''Mammamia profuga'' is a species of cave-dwelling millipede in the family Julidae. The only known species of the genus ''Mammamia'', it was described in 2011 from a specimen discovered in a cave in Italy. Description ''Mammamia profuga'' measures about 26 mm (1 inch) long, and 1.5 mm wide, consisting of around 50 body segments, the last two without legs. The body and legs are pale yellow in color, without markings, and the walking legs are about 2.25 mm long, except for the first pair in males, which are small and hook-like, as in other julidan millipedes. The species completely lacks eyes or ocelli. Like all members of the order Julida, mature males have two pairs of highly modified legs, the gonopods, consisting of the 8th and 9th pair, and in ''Mammamia'' the anterior (forward-most) gonopods are slightly longer than the posterior gonopods.

Julidae
Julidae is a family of millipedes in the order Julida, containing more than 600 species in around 20 genera. Its members are largely confined to the Western Palaearctic, with only a few species extending into the Oriental and Afrotropical realms. They are united by a characteristic form of the mouthparts, and are classified in the superfamily Juloidea of the order Julida, alongside the families Trichoblaniulidae, Rhopaloiulidae and Trichonemasomatidae. Genera The family consists of the following genera: Select species Examples of species contained within this family include: * '' Brachyiulus pusillus'' * '' Cylindroiulus punctatus'' * ''Tachypodoiulus niger'' * ''Ommatoiulus moreletii ''Ommatoiulus moreleti'' (spelt ''moreletii'' in older publications), commonly known as the Portuguese millipede, is a herbivorous millipede native to the western Iberian Peninsula where it shares its range with other ''Ommatoiulus'' species.

Titanophyllum
'' Titanophyllum spiliarum '' is a species of cave-dwelling millipede in the family Julidae. The only known species of the genus ''Titanophyllum'', it was described in 2011 from specimens discovered in a cave in Greece. It has several unusual characteristics including eyelessness and a small hook on its hind-most body section that may be involved in keeping the animal ‘locked’ when it coils-up defensively. Description ''T. spiliarum'' specimens measure 17 – 33 mm in length and 1 to 1.4 mm wide. The pale yellow body consists of a head followed by 47-61 body segments with legs, 1-2 legless segments, ending in a telson (legless, last body segment). The walking legs are about 80% the body width. Eyes are absent. Like other members of the Julida, mature males have two pairs of highly modified legs, the gonopods, in place of the 8th and 9th pair of walking legs. Unusual among Julid millipedes, the telson possesses a small, forward-projecting hook on the hypoproct or sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod Eye
Apposition eyes are the most common form of eye, and are presumably the ancestral form of compound eye. They are found in all arthropod groups, although they may have evolved more than once within this phylum. Some annelids and bivalves also have apposition eyes. They are also possessed by ''Limulus'', the horseshoe crab, and there are suggestions that other chelicerates developed their simple eyes by reduction from a compound starting point. Some caterpillars appear to have evolved compound eyes from simple eyes in the opposite fashion. The arthropods ancestrally possessed compound eyes, but the type and origin of this eye varies between groups, and some taxa have secondarily developed simple eyes. The organ's development through the lineage can be estimated by comparing groups that branched early, such as the velvet worm and horseshoe crab to the advanced eye condition found in insects and other derived arthropods. Eyes and functions Most arthropods have at least one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave Millipedes
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms ...

Millipedes Of Europe
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 or d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Italy
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichopetalum Whitei
''Trichopetalum whitei'', common name Luray Caverns blind cave millipede, is a rare troglobitic (obligate cavernicolous) millipede of the upper Potomac River drainage in four Virginia counties and three West Virginia counties. It has been recorded from 12 caves across this range, including the Luray Caverns where it was first discovered and described. Description ''T. whitei'' is an eyeless, white (unpigmented) millipede. In common with all trichopetalids, it has rows of very elongate segmental setae extending in rows along the dorsal side. Proper identification requires microscopic examination and dissection of the gonopods (copulatory apparatus) by a specialist skilled in millipede identification. Ecology and range ''T. whitei'' is a troglobite and occurs only in caves, especially occurring on damp, rotting wood. ''T. whitei'' is presumably omnivorous, although nothing is known of its feeding preferences. Feeding is presumed to consist of picking up or scraping material from ...

Province Of Taranto
The province of Taranto ( it, provincia di Taranto; Tarantino: ; Salentino: ), previously known as the province of the Ionian, is a province in the Apulia region of Italy. Its capital is the city of Taranto. It has an area of , and a total population of 581,092 (2017). There are 29 ''comuni'' (singular: ''comune'') in the province, all of which are listed at comunes of the Province of Taranto. The coat of arms of the province contains a scorpion, which Pyrrhus is thought to have seen when looking down at Taranto. History When Italy was unified, the province of Lecce was formed; the western section of this later became the current province of Taranto. On 23 September 1923, Taranto became the capital of a new province based on the ancient Terra d'Otranto, in recognition of the important role the city had served since ancient times. Until 1951, the new province was called the "Province of the Ionian". The scorpion on the city's coat of arms may have been used as its emblem in anci ...

Gonopod
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 Opiliones penis, 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 decapoda, decapod crustaceans, gonopods are modified swimming appendages (pleopods). The anterior two pair of pleopods in males are modified for sperm transferring, with dif ...
