Drakensberg Creeper (Opisthacanthus validus) #CritterThursday
Scorpions stridulate by rubbing their chelicerae
(mouthparts) together to produce a hissing sound. In some cases, they may drag
the telson (sting) over the body segments (tergites) to produce a sudden
scraping sound in an attempt to frighten off a predator.
This is a medium sized scorpion of around 9 cm with the tail
extended. It is black in colour, but
often with a muddy appearance. It sometimes has lighter coloured legs and a lighter
tipped tail.
It is common across its range, occurring under rocks often
at high altitudes in areas like the Drakensberg.The sting of this species may
cause pain but is not medically important.
