RE:Spidy senses are tingling hereIf you want to see a spidy sense in action, check out the introduction of a cricket into an enclosure with a tarantula some time. The hairs on its body move as it picks up on the presence of the cricket.
Many years ago I brought a tarantula in an aquarium into an acounting office for entertainment. There were about a dozen people closely peering at the dramatic scene about to unfold, when it unexpectedly pounced. Two secretaries ended up on their asses in the ensuing fright and panic.
Mr. T's fame in that office was assured for all time.
