Study Tests Hypotheses About Light


Prey Capture Attempts and Light

Studying where marine predators find prey and what type of prey they attempt to capture is challenging. The authors of this paper specifically wanted to test the hypothesis that anti-predator light flashes from bioluminescent prey would be closely associated with prey capture attempts. To test this, they created a biologging device containing a fast-sampling light sensor, location, and movement sensors to better understand interactions between southern elephant seals and bioluminescent prey.
