Urodacus novaehollandiae

This member of the Urodacus genus is found coastally from South Australia through to Perth in Western Australia. In South Australia it is most commonly found occupying coastal dune areas, digging deep meandering burrows in shellgrit soils. In Perth WA, the scorpion can be found further inland digging in harder soils. The western and eastern forms are different in colour and some morphologies, such has size of keels on hands.
This species will often block the burrow entrance during different times of the year depending on the degree of it's activity. Blocking can occur if conditions are very desiccating or if the scorpion is undergoing a molt or having young.
