Scorpions sometimes capture and crush prey with their pedipalps and do not use their sting t o inject venom . Experiments were conducted to test the hypothesis that sting use is selective, resulting in conservation of venom . Sting use in relation to prey size and activity was studied in two African scorpions, Parabuthus liosoma and P. pallidus . Restrictive use of the sting was observed in bot...

OBJECTIVES To study the clinical aspects and frequency of scorpion stings in Riyadh region of Saudi Arabia. METHODS Clinical aspects and frequency of scorpion sting cases reporting to 2 referral hospitals in the Riyadh region of Saudi Arabia were analyzed during May 2006 to April 2008. Data on demographic status, date and time of sting, sting site, scorpion color, clinical manifestations, and...

BACKGROUND The different features of scorpions can be successfully described by their nesting and burrowing behaviors. There is little information about burrowing activity of Iranian scorpions. METHODS The current study was performed to compare the burrowing behavior between two burrowing Iranian scorpions, Scorpio maurus and Odonthubutus bidentatus by describing 30 nests of each species rega...

Khuzestan province has the highest rate of scorpion sting in Iran. This is a study to identify these scorpions in Khuzestan. In this study 418 scorpions were kept in the ethyl alcohol 70%, each being studied by stereomicroscopy and diagnosis key separately. 120 (28.7%) Androctonus crassicauda, 104 (24.9%) Hemiscorpius lepturus, 91 (21.7%) Mesobuthus eupeus, 86 (20.65%) Compsobuthus matthiesseni...

The distribution and behavior of foraging animals usually imply a balance between resource availability and predation risk. In some predators such as scorpions, cannibalism constitutes an important mortality factor determining their ecology and behavior. Climbing on vegetation by scorpions has been related both to prey availability and to predation (cannibalism) risk. We tested different hypoth...

This review describes the history of taxonomic research on scorpions and provides an updated checklist and key of the scorpions currently known in China. This checklist is based on a thorough review of the extant literatures on scorpion species whose presence has been confirmed in China through field expeditions and examination of scorpion collections, excepting a few members that have no clear...

The hypothesis that fluorescence in scorpions functions in the detection of ultraviolet light was tested. We reduced the fluorescence of scorpions by prolonged exposure to ultraviolet light on a 16:8 h light:dark cycle and compared their activity levels and light environment choices to unmodified scorpions in simple arenas that were half in shadow and half exposed to light. Three different ligh...

background: the different features of scorpions can be successfully described by their nesting and burrowing behaviors. there is little information about burrowing activity of iranian scorpions. methods: the current study was performed to compare the burrowing behavior between two burrowing iranian scorpions, scorpio maurus and odonthubutus bidentatus by describing 30 nests of each species rega...

Sky island scorpions shelter under rocks and other surface debris, but, as with other scorpions, it is unclear whether these species select retreat sites randomly. Furthermore, little is known about the thermal preferences of scorpions, and no research has been done to identify whether reproductive condition might influence retreat site selection. The objectives were to (1) identify physical or...
