Euastacus sulcatus

Species of crayfish

Euastacus sulcatus, also known as the Lamington crayfish, is a freshwater crayfish, or "yabby", native to Australia. It is commonly bright blue in colour although also existing in a red and white, rusty red, brown, green, orange and completely white variations are found all around its known region. They can be found roaming the forest floor when conditions are damp, usually after substantial rainfall, actively searching for a mate, new territory or food. When threatened, it raises its front two powerful pincers and will readily pinch any potential predator. The spiny crayfish has zero native predators by the time it reaches full-size maturity, although since the introduction of feral animals such as foxes and cats, it has suffered from predation not evolved to defend itself against. Due it its magnificent coloration it has also been targeted as a aquarium pet or even winding up on barbecues. This species is listed as protected and is an offence to trap/remove or harm this species, with on-the-spot fines of up to $522.
