Scourge scorpios

the scourge scorpios (Uropygi) are an order of the Kieferklauenträger and at the same time the Arachnids(Arachnida). World-wide about 180 kinds are well-known, which can be assigned two very different subordinations. The dwarf scourge scorpios (Schizomoida) reach body lengths of maximally 18 mm, in contrast to this are long the representatives of the Thelyphonida up to 75 mm (without appendix of tail). The animals inhabit the Tropics and Subtropen.

building of the scourge scorpios

the figure of the scourge scorpios reminds of that of the scorpios, which consists tail-like final part of the abdomen however only of three segments and endsin an arranged appendix of tail (Flagellum). As is the case for the scorpios the Pedipalpen is also here transformed and with shears provided to powerful catch legs. The first pair of run legs, which is put on as with the scourge spiders to long palpation organs with increased number of leg members, is remarkable.Accordingly the animals on only 3 pairs of legs run like the Sechsfüsser. The Kieferklauen (Cheliceren) is zweigliedrig and for tearing the booty up is used.

On both sides the Flagellums large military glands flow, with which the animals can spray a military secretion. Due to the mobility of the abdomenit comes out as purposeful jet. With the kind Mastigoproctus giganteus consists it of 84% acetic acid, 5% Caprylsäure and 11% water. These animals can squirt the secretion up to 80 cm far and it burn in the eyes and on thatMucous membranes, if one is met of it.

reproduction and development

as with the scorpios also with the scourge scorpios the female is pulled by the male over a before put down sperm cells package (Spermatophore). However the female seizes either the abdomen (with the Thelyphonida)or the button-like thickened Flagellum (with the Schizomida) of the male and can be pulled over the sperm cells package. The males of the Thelyphonida often still help with their particularly transformed Pedipalpen , by plugging and then breaking the sperm cells package formally into the female genital aperture.

In onethe female the eggs puts underground breeding chamber into a particularly designed Brutsack, which it carries at the abdomen with itself. The Prä nymphen holds on after slipping with detention rags at the legs at the abdomen of the nut/mother, afterwards they release. Four further followStriking doing gene to the animals are sex ripe (with Mastigoproctus two to four years). Each Häutung takes place in particularly a cave dug for it in which the animals remain several months.

systematics of the scourge scorpios

the scourge scorpios become, as previously mentioned, in two morphologically muchdifferent subordinations divided, which are called Thelyphonida and Schizomida (also dwarf scourge scorpios).

Thelyphonida

with the Thelyphonida covers an unstructured cover the entire front body. These animals are very large compared with the representatives of the Schizomida with maximally 75 mm of body length. Those Pedipalpen are extremely large and with thorns as well as large shears reinforced. The Flagellum is long and vielgliedrig. The representatives of this group live predominantly in the rain forests of the indopazifschen region and American region, a kind live in Africa. Mastigoproctus giganteus lives particularly inthe southern states of the USA

dwarf scourge scorpios (Schizomida)

these animals are very small with maximally 18 mm of body length. They live particularly in the soil and in caves. The front body segments possess own in each case dorsal shells, in addition the animals are eyeless. The Pedipalpen is slimand without shears, which thickens Flagellum briefly and with the male button-like. The dwarf scourge scorpios are domestic in all tropical regions of the earth.
