Selenocosmia stirlingi is a species of tarantula (family Theraphosidae) that is native to the arid regions of Australia.
[1] This species is largely fossorial, living in burrows deep underground, however males are sometimes encountered during the breeding season.
[4] Barking spiders wait in their burrows for insects, lizards or frogs to come near the entrance before grasping and injecting venom into them.
They have a gill-like lung that requires humidity and strong claws that enables them to dig burrows and stay cool.
Barking spiders also have bushy feet with some secreted oil which produces a suction-cup ability, which allows them to easily climb up steep rocks in the desert.
