DNA-based Technique Allows Researchers to Determine Age of Living Beluga Whales in Alaska

Researchers can now determine the age and sex of living beluga whales in Alaska's Cook Inlet thanks to a new DNA-based technique that uses information from small samples of skin tissue.

Accurate age estimates are vital to conservation efforts for Cook Inlet belugas, which were listed as endangered following a significant population decline in the 1990s. Previously, researchers could only determine the age of beluga whales by studying the teeth of dead animals.
