Murray crayfish

The Murray crayfish (Euastacus armatus) is a large freshwater crayfish native to southeastern Australia. It can grow over 40 centimeters long and is known for its robust body and strong claws. Typically found in cool, fast-flowing streams and rivers, it plays a vital role in its ecosystem by helping break down organic matter. It is also important commercially and ecologically, but its population has declined due to habitat loss and overharvesting. Recognized as a vulnerable species, conservation efforts aim to protect its habitat and ensure its survival.
