hairy thick-tailed scorpion is large, about 140 mm in length and is black in
colour. It is often seen during the day and is common from the Northern Cape
and Namibia. Besides its normal prey it also captures lizards and mice.
Robertson et al. (1982) showed that water loss in this
species was very low and furthermore that there was good evidence of
osmoregulation such that the osmolarity of the haemolymph remained much the same
with increased weight loss (mainly from dehydration) whereas in
Opistophthalmus capensis, which was also studied, osmolarity of the
haemolymph increased with weight loss.
