This species (Parabuthus transvaalicus) is by far the most venomous scorpion species found at Ingwelala.
Classified as Highly Venomous, the Transvaal Thicktail Scorpion is incredibly large and easily recognisable by the almost completely dark brown to black colouration and a very thick, hairy tail. The pincers are notably thin and often much lighter in colour. With the tail extended, this impressive species can reach up to 15cm in length.
Usually found in bushveld habitats, this species favours rocks, debris, leaf litter and logs as hiding spots, and can often be found lurking in any dark, humid or moist space in the lowveld. This species is rarely found above ground level or in vegetation and will mostly be found low down where any crevice provides shelter. Most of these scorpions are found by accident when an object is moved, and the scorpion is left exposed. Unfortunately, this can often lead to unexpected stings when hands or feet find themselves in the wrong place at the wrong time. A sting from this species can be life-threatening and requires anti-venom. Without anti-venom, chances of survival and/or recovery are much smaller, and may take an extended period.
Did you know?
This species is known to be able to eject or spray venom for up to 30cm! This is known to occur in a few species in the genus Parabuthus and not in any others. The Transvaal Thicktail Scorpion favours this secondary defence response to deter threats. A common occurrence for animals is therefore envenomation of the eyes as opposed to actual stings. In humans, however, multiple stings are common, as scorpions will assess humans as a “bigger” threat. This is also intensified by us accidentally touching them, increasing the “threat level”.
Fun Facts:
- Female scorpions will carry their young on their backs to keep them safe and move them around!
- If you want to determine how venomous a scorpion in Southern Africa is, there is a venomosity rule-of-thumb you can use based on how the scorpion looks.
This is determined by the thickness of the pincers and tail. It is still important to treat each sting symptomatically, though, as each person’s reaction will be different and unique.
NOTE: There is currently a severe shortage of snake, scorpion and spider anti-venom in the country!
