text: Ant-mimicking spiders face several challenges : they generally develop slimmer abdomens and false `` waists '' in the cephalothorax to mimic the three distinct regions ( tagmata ) of an ant 's body ; they wave the first pair of legs in form to their heads to mimic antennae , which spiders lack , and to conceal the fact that they have eight legs rather than six ; they develop large color patches round one pair of eyes to disguise the fact that they generally have eight simple eyes , while ants have two compound eyes ; they cover their bodies with reflective hairs to resemble the shiny bodies of ants .
