Correctional Services spokesman Manelisi Wolela has denied allegations that student leader Mcebo Dla.
Tarantula bites, though painful, are not poisonous to humans, though some people are allergic to the venom. Some tarantulas can also shoot the "hairs" off their legs, and they can pierce human skin and cause discomfort. Tarantulas have skeletons on the outside of their bodies, like crayfish and crabs. They shed these exoskeletons regularly - normally by lying on their back. These exoskeletons are very fragile, so if a tarantula is dropped from a low height, it will shatter and die.
