The wolf spiders, family Lycosidae, hunt as they walk over the ground, but also by waiting patiently at a likely spot. Four of the eight eyes are large and allow good vision. But a more important adaption for capturing prey are minute hair-like setae called Trichobothria. Not only can these organs detect minute vibration, but in concert they give the spider directional information. The wolf spider can pounce several centimeters sinking its fangs into prey without warning.
