Very Legal. It's exotic so unless there's a local species of Vinegaroon and Overseas species are highly Hybridisible (yes yes, not a word) then it's totally fine. Getting them however could be a issue, as most overseas dealers will only send to SA if you purchase a large amount to cover their costs for permits and the actual shipping. Although, there are lots of guys who would gladly swap anything for local Thick Tailed scorpions
