User's notes

This bird-dropping spider was sighted at ANBG’s Rainforest Gully and typifies why these spiders are so-called and how they are usually seen. The spider is sitting with its body raised up at an angle, elevating its eyes and enhancing its all-round vision. The spider is surrounded by the silk-covered remains of previous prey. The overall impression is of a bird-dropping spread out across a leaf. The first and fourth images are a rear view showing what appears to be a feline-like face with ears, eyes, nose and mouth, presumably an evolved visual deterrent against predators. The second image shows a front view with the spider’s long legs drawn up around its head end. The third image is a side view showing the remains of silk-covered prey on either side of the spider. The final image shows how this small but effective predator appears when seen from above, poised on a leaf in its ambush position.
