Seal Whiskers Lead to New Foraging Info

A new paper uses the whisker length of northern elephant seals to study how “stable isotope analysis of keratinized tissues” can tell them more on foraging ecology.

The study used Wildlife Computers SPOT and Mk-9 tags to study location and diving behavior data corresponding to the growth of the whiskers pulled for analysis.

Researchers found the stable isotope analysis of whiskers can be used to quantify the foraging behavior of northern elephant seals with satellite telemetry validating the behavior.
