Australian scorpion venoms have been poorly studied, probably because they do not pose an evident threat to humans. In addition, the continent has other medically important venomous animals capable of causing serious health problems. Urodacus yaschenkoi belongs to the most widely distributed family of Australian scorpions (Urodacidae) and it is found all over the continent, making it a useful m...

Scorpions possess two types of visual organs, the median and lateral eyes. Both eyes consist of simple ocelli with biconvex lenses that differ in structure and function. There is little variation in the number of median ocelli across the order. Except for a few troglomorphic species in which the median ocelli are absent, all scorpions possess a single pair. In contrast, the number of pairs of l...

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...
