Hinterland spiny crayfish

What does it look like?

The hinterland spiny crayfish is a small freshwater crayfish found only in South East Queensland and north-eastern New South Wales. Its colouration ranges from dark green to brown with a blue line along the flanks and a cream underside. The legs are light blue. Its pincer-like claws have a distinct branching pattern with a greenish tint tipped in brighter blue. 

Where does it live?

The hinterland spiny crayfish has a limited distribution and is one of the smallest known populations of any Euastacus species. It has been found in sections of upper Currumbin Creek, Mudgeeraba Creek, Little Nerang Creek, Nerang River, and Tallebudgera Creek in the Gold Coast hinterland and the Springbrook National Park area.

Ecology & habitat

The hinterland spiny crayfish inhabits upstream ephemeral waterways, avoiding open fast flowing sections of creeks and rivers. They make extensive burrows amongst rocks and gravel that reach into the local water table, often in areas with minimal surface water. The species appears to spend most of its time in these burrows and is rarely seen. Their breeding habitats and life cycle are largely unknown and requires further research.

How is its survival threatened?

• Climate change impacts, such as drought and flooding conditions, and increased fire risk
• Habitat loss and degradation from urban development
• Drawdown of the local water table through commercial water extraction
• Other pressures on habitat including weed invasion and fragmentation

How can we help?

• Improve understanding of the species distribution and life cycle
• Protect existing populations and remaining habitat located on private property and Council land
• Restore and/or expand habitat areas of existing populations
• Investigate funding opportunities to undertake further research and monitoring
