Two-tailed Spider

Tamopsis spp.

Two-tailed Spiders are a genus of small, cryptic spiders found in Australia, easily recognized by their pair of exceptionally long spinnerets which resemble a 'tail'. These spiders are masters of camouflage, with their mottled grey-brown bodies blending in perfectly with the tree bark on which they live. They are not pests and are harmless to humans. Their most remarkable feature is their unique hunting method: instead of building a web, they use their long spinnerets to rapidly encircle and immobilize prey with a spray of sticky silk. They are a fascinating example of the diversity of spider hunting strategies in the Australian bush.
