The hairs on a tarantula's body sense vibrations in the air. This helps the spider find its way around and hunt in the dark. The hairs on its body break off easily and irritate the skin of many animals. Tarantulas use their back legs to flick these hairs at enemies.
Lion-killing flies
Lion-killing flies Swarms of biting flies, Stomoxys calcitrans, have
killed at least six lions in Tanzania's Ngorongoro Crater wildlife
park. The blood sucking flies have sharp, file-like teeth that they
use to break through the skin of warm-blooded animals. 62 more
lions have been seriously injured by these swarms of flies that
"bite the lions and then keep biting their wounds, inflicting a lot
of pain and traumatizing them." MARCH 17, 2001
