Did you know? White-clawed crayfish are a Keystone Species and Ecosystems Engineers. This is because they play an important part in the food web whilst also shaping their underwater environment to the benefit of many other native species. So, they're kind if a big deal! 😎 📸Lucy Atkinson

HydroMoth underwater acoustic recorders capture sounds during crayfish interactions, while video cameras record their behavior. 👂🔊📹 By matching sound with video, researchers can explore whether specific sounds are linked to aggressive, defensive or other behaviors.

🦞 What can scientists learn by listening to crayfish? PhD student Abdullah Alkinani is studying interactions between native Signal Crayfish & non-native Ringed Crayfish. Researchers use a model fish to simulate a predator and study how crayfish respond—without exposing them to a live predator. 🐟🦞

The team also uses BORIS (Behavioral Observation Research Interactive Software) to identify behaviors like movement, escape attempts, attacks & defensive postures. Together, these tools turn video into behavioral data.🦞🔬 Tune in next week for more on this experiment & another layer of technology!
