Taxonomy

The Pilbara death adder was described by Raymond Hoser in 1998.[2] The specific name, wellsi, is in honor of Australian herpetologist Richard Walter Wells.[3]

Description

Dorsally, A. wellsi is usually brick red, with narrow, close-spaced gray crossbands. Individuals called "melanistic" have a black head, and the crossbands, which are wider, are yellowish brown, edged with black.[4]

Distribution and habitat

A. wellsi is found in the Hamersley Range and the Chichester Range in the Pilbara region in northern Western Australia.[1] The preferred habitats of A. wellsi are grassland, shrubland, and rocky areas.[5]

Reproduction

A. wellsi is viviparous.[1]

gollark: Meh, we have 2000 or so, the system adds more when we go above 50% use.
gollark: They ran at full back when the array was really tiny during the coal crisis.
gollark: The solar arrays have not run at their full power output for some time.
gollark: A few hundred MW.
gollark: But the actual track is 1 way unsignalled. Very straight though.
