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 Leach, 1814 *Rhopaloiulidae Attems, 1926 *Trichoblaniulidae Verhoeff, 1911 *Trichonemasomatidae Enghoff, 1991 ;Nemasomatoidea Bollman, 1893 *Chelojulidae Enghoff, 199 ...

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] |
