Sparassidae are a family of spiders known as Huntsman spiders because of their speed and mode of hunting.
As adults, huntsman spiders do not build webs, but hunt and forage for food: their diet consists primarily of insects and other invertebrates.
They tend to live under rocks, bark and similar shelters but will frequently wander into homes and vehicles.
Sparassidae use venom to immobilise prey and to assist in digestion.
They have been known to inflict defensive bites, but are not widely regarded as dangerous to healthy humans.
Sparassidae occur in practically all warm temperate to tropical regions of the world.
Northern Europe has one species: Green Huntsman Spider (Micrommata virescens).
Jahtihämähäkkien laajalla heimolla on vain yksi edustaja Pohjois-Euroopassa: viherhämähäkki (Micrommata virescens).
Heimon lajit eivät kudo verkkoja, vaan saalistus perustuu väijymiseen ja nopeaan iskuun.
