Freshwater crayfish are amazing animals that are not restricted to aquatic environments. Paul and I were driving through the Great Sandy National Park, Queensland and we discovered burrows in the grassy verges. Now finding the burrow is one thing, finding the grayfish is another thing all together.
Euastacus hystricosus is Queensland’s largest giant spiny crayfish species. It is a crayfish covered in numerous sharp spines that grows to a huge size. Found in the upper reaches of the Mary and Brisbane rivers, the ACP has been researching this amazing species.
This is one of four terrestrial Cherax crayfish that the ACP is researching. Cherax sp 1 from the Murray River is currently under description. Cherax rotundus from Fletcher Qld has had 2 papers published and research is ongoing. Cherax setosus from the Newcastle region NSW has just been redescribed and that only leaves Cherax punctatus. All Queensland Cherax species are currently under review by the ACP with a full review and revision of all species is due by 2013.
