DSC_9066 Intertidal spider (Desis marina) breeding pair's underwater web tunnel, revealed on the underside of a submerged rock. This endemic spider occurs on rocky coasts all around NZ and the Chatham Islands. It has a most unusual habitat, which extends underwater from high-tide level down to below normal low tide. Underwater it finds sufficient air pockets trapped amongst the rocks and seaweeds, which are only exposed at exceptionally low tides. The spiders survive in their submerged retreats for up to 19 days at a time, even foraging underwater. Because they have a lower respiration rate than other spiders, they can survive very low oxygen concentrations. Aquarium Point, Otago Harbour *
11005-16209 Slater-eating spider (Dysdera crocata) a distinctive, introduced European spider, ussually found under stones in warm dry areas. It has large opposable fangs for capturing and eating slaters - not normally popular as prey because of unpleasant chemicals they secrete to defend themselves - but by holding the slater away from its body, the spider avoids these unpleasant chemicals while it feeds.

11005-16518 Long-legged cellar spider, or daddy longlegs (Pholcus phalangioides) introduced from Europe. Common and widespread in NZ, it prefers to live indoors where its flimsy, messy webs are found up in the more neglected corners near the ceiling. It uses its long legs to quickly wrap its snared victims in silk from a safe distance, even trapping other spiders in this way. Auckland *
