An expedition for The Hairy Cataract Crayfish Euastacus pilosus

We arrived on site just on dark and set up camp as the first priority whilst there is light. Were in far northern NSW near the Qld border in the drainage of the Clarence River.

Next, is a steak sandwich for dinner and then get ready for a spotlight of the creek. You can amass a heap of biological info on a species by observing its activities both day and night.

The stream is crystal clear, shallow and flowing beneath tall sedges that line the base of the valley.

That night we learned a bit more about the species and when it becomes active etc. This info just adds to the knowledge base on the species. The next morning we got up had a bacon and egg sandwich and did a first light survey of the creek.

This is what we are after The Hairy Cataract Crayfish Euastacus pilosus. This is as big as they grow so quite small on the scheme of things but very pretty. This little girl has a health batch of eggs.

After the creek survey, we packed up and headed off to the next survey site.
