Abstract All species of scorpions can inject venom, some them even with the possibility killing a human. Therefore, early detection and identification are essential to minimize scorpion stings. In this paper, we propose novel automatic system for recognition using computer vision machine learning (ML) approaches. Two complementary image-processing techniques were used proposed method accurately...

Scorpions are generalist predators, capturing a great variety of arthropods including even small vertebrates (Polis, 1990), however, they are also subject to predation, especially by vertebrates such as amphibians, reptiles, birds and mammals (Polis et al., 1981; McCormick and Polis, 1990). Regarding the invertebrates, there are reports of predation by coleopterans, chilopods, solpugids, others...

The experiments dealt with in this paper were devised to ascertain (1) the relative effectiveness as photoreceptors of the whip-tail scorpion's median eyes, lateral eye groups, and cutaneous sensitive areas, and (2) the effect on orientation produced by symmetrical and by asymmetrical interference with the photoreceptive mechanism. Each of the receptors was eliminated unilaterally and bilateral...

Aim Historically, research on global distribution patterns has mostly concentrated conspicuous organisms and thus a large proportion of biodiversity Earth remains unmapped. We examined the palpigrades, poorly studied group low dispersive arachnids specialized to subterranean life. asked what are ecological factors driving their distributions, extent sampling bias may influence observed patterns...
