Australian Yabby
Cherax destructorAlso known as Common Yabby, Yabbie, Blue Yabby, Destructor Crayfish
Australian yabbies are highly resilient freshwater crayfish famous for their ability to survive severe droughts by burrowing deep into riverbeds and farm dam walls. They use their powerful, spade-like claws to excavate complex tunnel systems where they can aestivate in damp clay for years until rains return. These opportunistic scavengers play a vital role in inland waterways, recycling organic matter and serving as a primary food source for many native fish and birds.

Vulnerable
Large claws can deliver a painful pinch; handle with care behind the carapace.
Equipped with powerful, muscular claws designed for defense and digging that can easily break human skin.
Never grab them by the claws or from the front; pick them up securely from the back of the shell.Classified as vulnerable due to localized declines from habitat loss, river regulation, and land clearing.
Avoid disturbing their burrows during dry spells and release any wild-caught individuals back into their home waters.- Spotting Burrows: Look for distinctive chimney-like mud mounds along the banks of dams and creeks.
- Safe Handling: Pick them up gently from behind the thorax to avoid the reach of their sharp claws.
- Night Watching: Use a red-filtered flashlight to observe them foraging along the shallows after dark.
