Water flea can smell fish and dive into the dark for protection

(University of Cologne) Zoologists at the University of Cologne have discovered the messenger substance responsible for the flight of the small planktonic crustacean Daphnia from fish in lakes. This animal's dive into deeper waters has significant consequences for the concentration of algae in the lake's ecosystem. The scientists hope that in future, a better understanding of this interaction might help restore the biological balance in lakes.
