Selenocosmia crassipes

Selenocosmia crassipes, synonym Phlogius crassipes, also known as the "Queensland whistling tarantula" (or "barking spider") is a species of tarantula native to the east coast of Queensland, Australia. The name "whistling tarantula" comes from its ability to produce a hissing noise when provoked, a trait it shares with other Australian theraphosids.[2] This hissing is produced by the spider stridulating a patch of setae associated with its chelicerae. It has also been called the "eastern tarantula".[3] The species name crassipes is Latin for "fat leg" referring to the relatively fat front legs.

Selenocosmia crassipes can attain legspans of up to 22 cm (8.7 in). Its body length, from eyes to the rear of its abdomen, measures between 6 and 9 cm (2.4 and 3.5 in), making it the largest Australian tarantula.
