Beluga whales keep switching mates and it may be saving their species
A 13-year DNA study of beluga whales in Alaska reveals that they frequently switch mating partners. Researchers believe this behavior helps the isolated population maintain genetic diversity and avoid the risks of inbreeding.
Why it matters
Understanding the reproductive habits of endangered or isolated species is crucial for conservation efforts and maintaining biodiversity.
Beluga whales are among the most challenging marine mammals to study. Much of their lives are spent beneath Arctic waters and sea ice, making direct observation difficult. Now, a long-term DNA study has provided rare insight into how a population of belugas in Bristol Bay, Alaska, forms family connections and maintains genetic health.
