Animal You | Scorpion | Scorpions are found on all major land masses except Antarctica. The greatest diversity of scorpions in the Northern Hemisphere is in the subtropics between the latitudes 23 ° N and 38 ° N. Be found in these latitudes, the diversity, the presence north of scorpions are the Scorpion Paruroctonus Boreas north to 50 ° N. Scorpions are now in almost all terrestrial habitats, including high altitude mountains, caves and intertidal zones, found with the exception of boreal ecosystems such as the tundra, high altitude taiga and the permanently snow-capped mountains different. Five colonies of scorpions (Euscorpius flavicaudis) established themselves in Sheerness on the Isle of Sheppey in the UK. This scorpion species is small and completely harmless to humans. This marks the northern limit of where scorpions live in the wild.
Scorpions are many fossils, including the Silurian deposits, coal deposits from the Carboniferous marina and Bernstein found. The oldest known scorpions lived around 430 million years ago in the Silurian period, on the bottom of shallow tropical waters. These first scorpions had gills instead of lungs book its current form. "Currently, 111 fossil species of scorpion are known. Unusually for arachnids, there are several species of scorpion Paleozoic or Mesozoic Cenozoic that. Grow different types everywhere could Eurypterida 10 centimeters (3.9 inches) long and 2.5 m (8.2 feet). The cephalothorax, also called the prosoma comprises the carapace, eyes, chelicerae (mouth parts), pedipalps (the pedipalps of scorpions have pincers, claws or commonly called claws). And four pairs of walking legs scorpion's exoskeleton is thick and durable and offers good protection from predators. Scorpions two eyes on the upper surface of the carapace, and usually 2-5 pairs of eyes along the front corners of the cephalothorax.
The pedipalp segmented, chelate (clawed frog) is added to immobilize the prey, defense, and sensory purposes. A Scorpio called darkened or granular raised ridges linear "keel" or taxonomically keels pedipalp segments and other parts of the body that are useful. Segment 2 is the basal plate with pectins. Each of the segments 3-7 mesosomal has a pair of vents, openings for the scorpion's respiratory organs, known as the lungs of the book. This fluorescence may play a role in detecting light scorpion. Scorpions have quite variable duration and actual duration of most species is not known. Scorpions. Yes in areas where temperatures can live 20-37 ° C (68-99 ° F), but subzero temperatures to survive the desert heat Scorpiops Scorpions kind of living in the mountains can bothriurid Asian scorpions from Patagonia and small scorpions Euscorpius Central all survive winter temperatures of about -25 ° C (-13 ° F). In Repetek (Turkmenistan), there live seven species of scorpions (referred Pectinibuthus birulai is endemic) in temperatures between -31-50 ° C (-24-122 ° F).
Scorpions exhibit photophobic behavior, especially for the recognition by their enemies, such as birds, centipedes, lizards, mice, possums and rats escape. Scorpions are opportunistic predators, small arthropods, although the larger species known to kill small lizards and mice. Scorpions have an unusual way of eating with chelicerae, small claw-like structures. Scorpions can only feed in liquid form, have external digestion. Any solid nondigestible (fur, exoskeleton, etc.) captured from pre-bristle cavity, which is expelled through the scorpion. Scorpions can consume large amounts of food in one sitting. This enables scorpions to survive long when deprived of food, some are able to survive 6 to 12 months of starvation. Scorpions differ very little, and their insoluble residues consisting mainly of nitrogen-containing compounds such as xanthine, guanine, and uric acid. Most scorpions reproduce sexually, and most species have males and females. However, some species such as Hottentotta hottentotta, caboverdensis Hottentotta, australasiae Liocheles, Tom columbianus, metuendus Tom, Tom serrulatus, stigmurus Tom, Tom Tom and trivittatus urugayensis to reproduce by parthenogenesis, develop a process in which unfertilised eggs of living embryos. Parthenogenetic reproduction begins after the last molting scorpion maturity and continues thereafter.
Sexual reproduction is accomplished by the transfer of a spermatophore of male to female, scorpions have a cut and complex mating ritual to do so. The courtship begins with understanding the male from the female with his pedipalps, the pair then "dance" as "ride à deux". This "dance", the male, the female leads in the search for a suitable place to deposit his spermatophore. When the male has identified a suitable location, he deposits the spermatophore and then the door female. Once the pairing is complete, the male and female will separate. The male generally retreat quickly, most likely to avoid being exploited by the female, although sexual cannibalism is common with scorpions. All known scorpion species possess venom and use it primarily to kill or paralyze their prey so that it can be eaten. The 1000 + known species of scorpion, only 25 have venom that is deadly to humans, most which are of the family Buthidae.
