Editing Austrelaps (section)

==Description==
There are three species of Australian copperheads: the [[pygmy copperhead]], the [[highland copperhead]], and the [[lowland copperhead]]. The pygmy copperhead is {{convert|60|cm|ft|abbr=on}} long, and lives in [[South Australia]] and on [[Kangaroo Island]]. The highland copperhead is {{convert|1.25|m|ft|abbr=on}} in length and lives in alpine areas of [[Victoria (Australia)|Victoria]] and [[New South Wales]]. The lowland copperhead reaches {{convert|1.75|m|ftin|abbr=on}} in length and lives in southern Victoria into [[Tasmania]]. Their colour varies a great deal, from a coppery mid-brown to yellowish, reddish, grey or even black, depending on the individual. The copper head colouring that gave rise to the common name is not always present. Some individuals also have visible markings just behind the head. Perhaps in consequence of their great variation, it was not realised until the second half of the 20th century that there were three different [[species]]. Venom toxicity has been measured at 0.5&nbsp;mg/kg subcutaneous, at least for the lowland copperhead.
