Most jumping spiders do not spin webs. They have a distinctive eye arrangement: two pairs in front, one pair in the middle and one pair behind giving them almost 360 degrees vision. They jump.
These spiders, members of the family Salticidae, are hunters which approach their prey by creeping closer before leaping on it from a standing start from a few centimetres away.
Do you think the spider is aiming for one of those ants?
