A dangerously venomous snake with tremendous variation in colour and pattern - some colour morphs are illustrated below. This snake is very abundant in close proximity to human dwellings and is involved in most snakebite deaths in Western Australia (six of last ten fatalities attributed to snakes).
Courtship - both individuals are dark coloured, but it is not unusual to see different coloured morphs mating or fighting.
Neonatal Gwardar - note dark head typical of young brown snakes.
