The barking spider, sometimes called the whistling spider, is an Australian farantula. When disturbed, they produced a sound by rubbing their palps over their fangs. The largest are found in Queensland, and some have been found in north-west Victoria.
Barking Spiders produce their barking sound by rubbing rows of spines on their palaps against spines on their lower jaw. This noise is used to deter predators.
The deserts are prone to flash flooding and Barking Spiders live in burrows with leaky rooves. The hairs on their body trap air bubbles during flash floods and the air pocket prevents them from drowning.
Barking Spiders have brush feet with claw tufts and a film of oil produced from a special gland which gives them a suction cup ability to climb smooth vertical surfaces.
