Guyandotte River Crayfish
Robust claws, a compact body, and life under large flat stones suit this endemic crustacean to swift upper Guyandotte tributaries.

The Guyandotte River crayfish uses stable slab and boulder cover in flowing water. Sediment that fills spaces, water-quality degradation, and severe watershed disturbance can erase shelter even when a channel still appears to be a stream.
Its tiny global range means local land and water decisions carry species-level consequences. Recovery focuses on habitat protection, monitoring, and reducing threats rather than turning occurrences into public collecting sites.

- Shelter
- Slab rock
Quick guide
- Habitat lesson
- Stable slab cover matters more than scenic water alone.
- Ethical choice
- Learn from shore; never disturb occupied rocks.
Recognize it through habitat and behavior
- Read the substrate
- Large embedded slabs with open shelter spaces matter.
- Keep rocks in place
- Turning cover can crush or expose hidden animals.
- Watch water clarity
- Fine sediment changes habitat beneath the surface.
- Protect the watershed
- Road, mine, and stream practices connect downstream.
Good to know
This is a protected species with conservation-sensitive occurrences. Do not collect crayfish, overturn slab rock, enter posted property, or publish precise locations.
