Southern elephant seals likely detect prey bioluminescence for foraging

Bioluminescence may play a key role in successful foraging for southern elephant seals, a deep-sea predator, according to research published Aug. 29 in the open access journal PLOS ONE.

The authors of the study, led by Jade Vacqui-Garcia, monitored the diving behaviour of four female southern elephant seals in the southern Indian Ocean that were also equipped with light detectors. The researchers found that increased bioluminescence was correlated with higher foraging intensity, suggesting that bioluminescence likely provides seals with valuable indications of prey occurrence.
