Julus (alternately written as Iulus) is a genus of millipedes in the family Julidae, containing the following species:
Helix is a genus of large, air-breathing land snails native to Europe and the Mediterranean region. They are the type genus of the family Helicidae, and are among the first animal genera described by Carl Linnaeus. Members of the genus first appeared during the Oligocene. Like most land snails, Helix species are hermaphroditic, and like other helicids, a courting pair will impale each other with hormone-rich love darts prior to exchanging sperm. Well-known species include Helix pomatia and Helix lucorum. Cornu aspersum – another well-known helicid – was originally described as a member of Helix, but the prevailing classification places it as the sole member of the sister genus Cornu.
Chilognatha is a subclass of the class Diplopoda, which includes the vast majority of extant millipede, about 12,000 species.
Lithobius is a large genus of centipedes in the family Lithobiidae, commonly called stone centipedes, common centipedes or brown centipedes.
Trochus is a genus of medium-sized to large, top-shaped sea snails with an operculum and a pearly inside to their shells, marine gastropod molluscs in the family Trochidae, the top snails.
The Scolopendridae are a family of large centipedes. Nearly all species in this family have four ocelli on each side of the head and only 21 pairs of legs, but there are exceptions: two scolopendrid species feature more legs, and some scolopendrid species are eyeless and blind. Two Asian members of this family, Scolopendra cataracta and Rhysidia ceylanica, are known to show amphibious behaviour.
Cormocephalus is a genus of centipedes of the family Scolopendridae, containing the following species:
Scolopendra is a species-rich genus of large tropical centipedes of the family Scolopendridae.
Tetragnatha is a genus of long-jawed orb-weavers found all over the world. It was first described by Pierre André Latreille in 1804, and it contains hundreds of species. Most occur in the tropics and subtropics, and many can run over water. They are commonly called stretch spiders in reference to their elongated body form and their ability to hide on blades of grass or similar elongated substrates by stretching their front legs forward and the others behind them. The name Tetragnatha is derived from Greek, tetra- a numerical prefix referring to four and gnatha meaning "jaw". Evolution to cursorial behavior occurred long ago in a few different species, the most studied being those found on the Hawaiian islands. One of the biggest and most common species is T. extensa, which has a holarctic distribution. It can be found near lakes, river banks or swamps. Large numbers of individuals can often be found in reeds, tall grass, and around minor trees and shrubs.
Spirostreptus is a genus of giant millipedes of the family Spirostreptidae. It contains the following species:
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.
Julida is an order of millipedes. Members are mostly small and cylindrical, typically ranging from 10–120 millimetres (0.39–4.72 in) 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.
Pachyiulus is a genus of julid millipedes containing the following species:
Pachymerium is a genus of centipedes in the family Geophilidae, containing the following species:
Orthomorpha is a genus of millipedes in the family Paradoxosomatidae containing approximately 50 species distributed in Southeast Asia.
Chordeumatida is a large order of millipedes containing some 1200 species with a nearly worldwide distribution. Also known as "sausage millipedes," they possess around 30 body segments behind the head as adults and reach about 25 mm (0.98 in) in length.
Geophilus is a genus of soil centipedes in the family Geophilidae largely considered to be synonymous with Brachygeophilus. It is a mostly holarctic genus characterized by a claw-shaped ultimate pretarsus, anterior porefields, complete or nearly complete coxo-pleural sutures at the prosternum, and incomplete chitin-lines. The generic name first appeared in Brewster's Edinburgh Encyclopaedia in 1814 as Geophilus electricus. Two species in this genus include centipedes with only 29 pairs of legs, the lowest number found in the family Geophilidae: G. persephones and G. richardi.
Rhysodesmus is a genus of flat-backed millipedes in the family Xystodesmidae. There are at least 90 described species in Rhysodesmus., ranging from El Salvador to the Southern United States.
Trigoniulus is a genus of millipede in the family Trigoniulidae. There are at least 90 described species in Trigoniulus.
Lychas is a genus of scorpions belonging to the family Buthidae. It is one of the most widespread genus of the scorpions, where the species are found throughout in Africa and Seychelles, and in the Oriental region from India to Melanesia.
