Parabuthus transvaalicus

Parabuthus transvaalicus (known as the Transvaal thick-tailed scorpion, dark scorpion, giant deathstalker, or South African flat tail) is a species of venomous scorpion from dry parts of southern Africa. Parabuthus transvaalicus grows to a length of 90–110 millimetres (3.5–4.3 in), and is dark brown or black in colour, so it is also known as the Black Thick-Tailed scorpion. Its pincers are thin, but its tail is thickened, with the sting segment being as wide as the rest of the tail. It is nocturnal, resting in a shallow burrow under rocks during the day. It resembles its congener P. villosus, which is less strictly nocturnal, hairier and has a more westerly distribution. The species is the largest (measuring up to 18 cm) and only diurnal Buthid in the world. Parabuthus transvaalicus is found in deserts, scrublands and semi-arid regions of Botswana, Mozambique, Zimbabwe ,some parts of the Namib Desert and South Africa. Parabuthus transvaalicus is a dangerous scorpion, which can both sting and spray its kurtoxin venom. The first droplet of venom differs from the rest, and is referred to as 'pre-venom'.
