Many marine organisms begin their lives as larvae, passively drifting or actively swimming their way through their early life stages. These microscopic planktonic organisms are extremely hard to tag and track, thus to detect them innovative research has had to be developed. Collaborators from University of California Davis and North Carolina State University have spent three decades developing a robot “larval mimic" that senses its environment, mimics the vertical swimming responses of larvae and relays its location.
