Porcellio achilleionensis is a terrestrial isopod species of the genus Porcellio. It is found in the Mediterranean region, specifically in Greece and the island of Crete. [1]
Porcellio achilleionensis is a small isopod, typically measuring around 10-15mm in length. It has a reddish-brown coloration, with a smooth, glossy exoskeleton. [2]
Porcellio achilleionensis is found in a variety of habitats, including rocky outcrops, scrubland, and Mediterranean forests. The species is most commonly found in areas with high levels of humidity, such as near streams or on shaded slopes. It is endemic to Greece and the island of Crete, where it is found in scattered populations. [3]
Like all species of Isopoda Porcellio achilleionensis directly develops from yolky eggs. Both the eggs and juveniles develop within a brood pouch called a marsupium until the first juvenile stage. The use of the marsupium eliminates the need for an external water source for early development since it is filled with fluid from the mother isopod.
Porcellio achilleionensis is not currently listed as a threatened species by the International Union for Conservation of Nature (IUCN). However, the species is considered to be rare, with limited populations found in specific areas. Habitat destruction and degradation, as well as pollution, are believed to be the main threats facing the species. Further research is needed to determine the conservation status of P. achilleionensis and to develop appropriate conservation measures. [4]
Armadillidium is a genus of the small terrestrial crustacean known as the woodlouse. Armadillidium are also commonly known as pill woodlice, leg pebbles, pill bugs, roly-poly, or potato bugs, and are often confused with pill millipedes such as Glomeris marginata. They are characterised by their ability to roll into a ball ("volvation") when disturbed.
The loggerhead sea turtle is a species of oceanic turtle distributed throughout the world. It is a marine reptile, belonging to the family Cheloniidae. The average loggerhead measures around 90 cm (35 in) in carapace length when fully grown. The adult loggerhead sea turtle weighs approximately 135 kg (298 lb), with the largest specimens weighing in at more than 450 kg (1,000 lb). The skin ranges from yellow to brown in color, and the shell is typically reddish brown. No external differences in sex are seen until the turtle becomes an adult, the most obvious difference being the adult males have thicker tails and shorter plastrons than the females.
Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda. Unlike members of some other woodlice families, members of this family can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals. This ability gives woodlice in this family their common names of pill bugs or roly polies. Other common names include slaters,potato bugs, butchy boys and doodle bugs. Most species are native to the Mediterranean Basin, while a few species have wider European distributions. The best-known species, Armadillidium vulgare, was introduced to New England in the early 19th century and has become widespread throughout North America.
Porcellio scaber, is a species of woodlouse native to Europe but with a cosmopolitan distribution. They are often found in large numbers in most regions, with many species preying on them.
The sawback angelshark is an angelshark of the family Squatinidae It is one of rarest species of sharks known to date, and one of the three species of angelsharks that inhabits the Mediterranean. The Sawback angelshark lives in sandy and muddy bottoms of the ocean at depths of 30-500m.
Porcellio is a genus of woodlice in the family Porcellionidae. These crustaceans are found essentially worldwide. A well-known species is the common rough woodlouse, Porcellio scaber.
Porcellio laevis is a species of woodlouse in the genus Porcellio. As the species epithet laevis as well as the vernacular name "swift woodlouse" suggests, the species is capable of quick bursts of speed when provoked.
Trichoniscidae are a family of isopods (woodlice), including the most abundant British woodlouse, Trichoniscus pusillus. Most species of woodlice that have returned to an aquatic or amphibian way of life belong to this family. Several species from the following genera live in water and on land: Titanethes, Cyphonetes, Alpioniscus, Scotoniscus, Bureschia, Brackenridgia, Mexiconiscus, Trichoniscoides, Cretoniscellus, Balearonethes and Cyphoniscellus.
A woodlouse is any crustacean belonging to the suborder Oniscidea within the order Isopoda. They get their name from often being found in old wood, and from louse, a parasitic insect, although woodlice are neither parasitic nor insects.
Hemilepistus reaumuri is a species of woodlouse that lives in and around the deserts of North Africa and the Middle East, "the driest habitat conquered by any species of crustacean". It reaches a length of 22 mm (0.87 in) and a width of up to 12 mm (0.47 in), and has seven pairs of legs which hold its body unusually high off the ground. The species was described in the Description de l'Égypte after the French Campaign in Egypt and Syria of 1798–1801, but was first formally named by Henri Milne-Edwards in 1840 as Porcellio reaumuri. It reached its current scientific name in 1930 after the former subgenus Hemilepistus was raised to the rank of genus.
The Balkan terrapin or western Caspian terrapin is a species of terrapin in the family Geoemydidae. It is found in the eastern Mediterranean region. While technically omnivorous, the terrapins are known to prefer meat. They can grow to 25 cm in carapace length, although hatchlings are usually only 3 to 4 cm in length.
Platyarthrus hoffmannseggii is a species of woodlouse which is closely associated with ants' nests, particularly those of Lasius flavus, Lasius niger and species of Myrmica, where it feeds on ant droppings or mildew. It is white, 4 millimetres (0.16 in) long, and has a distinctive oval shape and short antennae. Its distribution appears to follow those of the ants with which it lives, and the British Isles are the north-westerly limit of its range. Elsewhere, P. hoffmannseggii extends south to the Mediterranean Sea. It is found outside Europe in North Africa and Turkey, and has been introduced to Australia and North America.
Porcellio spinicornis is a species of woodlouse in the family Porcellionidae. This species is widespread in Europe, and has also been introduced to North America. It has wide spiny frontal lateral lobes.
Porcellio obsoletus is a species of woodlouse in the genus Porcellio belonging to the family Porcellionidae that can be found on islands like Crete, Cyclades, Cyprus, Dodecanese, Malta, North Aegean, and Sicily. It can also be found in such European countries as Albania, Croatia, Greece, Italy, Ukraine, and European part of Turkey.
Haplophthalmus danicus, also known as the terrestrial cave isopod or spurred ridgeback isopod, is a species of woodlouse in the family Trichoniscidae. It is naturally found in Europe, Southern Asia, and temperate Asia, however it has been introduced to North America. This species was likely introduced during original European settlement, and therefore has been well established in terrestrial communities.
Helleria brevicornis, the sole species of the monotypic genus Helleria, is a terrestrial woodlouse endemic to the islands and coastal regions of the northern Tyrrhenian sea. H. brevicornis is of interest due to its endemism, unique ecology and basal position in the suborder Oniscidea.
Porcellio hoffmannseggii, commonly called the titan isopod, is a species of woodlouse of the genus Porcellio described in 1833. This very large species is native to the southern Iberian Peninsula, Morocco and the Balearic Islands.
Porcellio scaber lusitanus is a subspecies of Porcellio scaber endemic to Spain and Portugal. Described in 1907 as Porcellio lusitanus the species was later lowered to a subspecies level despite being referred to as a form. It is highly likely that Porcellio scaber lusitanus are normal P. scaber with Allometric Growth.
Armadillidium maculatum, also known as the zebra isopod or zebra pillbug is an Armadillidium species of woodlouse, named for its black and white patterns. It is native to southern France.
