Pacific Northwest Arachnids
Lower surface of black and yellow garden spider from Sauvie Island,
west of Portland, OR....August 22, 1994.
Arachnids are characterized
by 4 pairs of jointed legs and a body divided into 2 major sebments. Antennae
are lacking from the head and none possess wings. Examples of arachnids found
in the Pacific Northwest include spiders, harvestmen ("daddy long legs"), scorpions,
mites, and ticks.
Spiders are the most visible arachnids in the northwest. Spiders
typically bite their prey with their long fangs, then inject a poison which
subdues the victim and also starts the digestion of the victim from within.
The spider then places its mouth on the victim and consumes the liquid contents.
