Mammamia (Måneskin Song)
''Mammamia profuga'' is a species of Troglofauna, 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 Julida, julidan millipedes. The species completely lacks Arthropod eye, eyes or Simple eye in invertebrates, 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.

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 arthropod leg, 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 transferr ...

Troglofauna
Troglofauna are small cave-dwelling animals that have adapted to their dark surroundings. Troglofauna and stygofauna are the two types of subterranean fauna (based on life-history). Both are associated with subterranean environments – troglofauna are associated with caves and spaces above the water table and stygofauna with water. Troglofaunal species include spiders, insects, myriapods and others. Some troglofauna live permanently underground and cannot survive outside the cave environment. Troglofauna adaptations and characteristics include a heightened sense of hearing, touch and smell. Loss of under-used senses is apparent in the lack of pigmentation as well as eyesight in most troglofauna. Troglofauna insects may exhibit longer appendages and a lack of wings. Ecological categories Troglofauna are divided into three main categories based on their ecology: * Troglobionts (or troglobites): species, or populations of species, strictly bound to subterranean habitats. * Troglo ...

Millipede
Millipedes (originating from the Latin , "thousand", and , "foot") 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 Latin for "thousand feet", no species was known to have 1,000 or more until the discovery in 2020 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, eat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julidae
Julidae is a family of millipedes in the order Julida, containing more than 600 species in around 20 genera.

Julida
Julida is an order of millipedes. Members are mostly small and cylindrical, typically ranging from in length. Eyes may be present or absent, and in mature males of many species, the first pair of legs is modified into hook-like structures. Additionally, both pairs of legs on the 7th body segment of males are modified into gonopods. Distribution Julida contains predominantly temperate species ranging from North America to Panama, Europe, Asia north of the Himalayas, Asir region, Saudi Arabia, and Southeast Asia. Classification The order Julida contains approximately 750 species, divided into the following superfamilies and families: ;Blaniuloidea C. L. Koch, 1847 * Blaniulidae C. L. Koch, 1847 * Galliobatidae Brolemann, 1921 * Okeanobatidae Verhoeff, 1942 * Zosteractinidae Loomis, 1943 ;Juloidea Leach, 1814 *Julidae Julidae is a family of millipedes in the order Julida, containing more than 600 species in around 20 genera.

Arthropod Eye
Eye#Apposition eyes, 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 Eye#Compound eyes, 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 Onychophora, velvet worm and horseshoe crab to the advanced eye condition found in insects and other Synapomorphy, derived arthr ...

Simple Eye In Invertebrates
A simple eye or ocellus (sometimes called a pigment pit) is a form of eye or an optical arrangement which has a single lens without the sort of elaborate retina that occurs in most vertebrates. These eyes are called "simple" to distinguish them from " compound eyes", which have multiple lenses. They are not necessarily simple in the sense of being uncomplicated or basic. The structure of an animal's eye is determined by the environment in which it lives, and the behavioural tasks it must fulfill to survive. Arthropods differ widely in the habitats in which they live, as well as their visual requirements for finding food or conspecifics, and avoiding predators. Consequently, an enormous variety of eye types are found in arthropods to overcome visual problems or limitations. Use of the term ''simple eye'' is flexible, and must be interpreted in proper context; for example, the eyes of most large animals are '' camera eyes'' and are sometimes considered "simple" because a sing ...

Province Of Taranto
The province of 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). The province contains 29 ''comuni'' (: ''comune''). 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 ancient times, on the suggestion of Pyrrhus of Epirus, who was an ally of Taranto in a war against Rom ...

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 su ... [...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 fr ...

Endemic Fauna Of Italy
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...
