Beluga whales keep switching mates and it may be saving their species
Key takeaways
- Beluga whales are among the most challenging marine mammals to study.
- The findings suggest that both male and female belugas reproduce with multiple partners over the course of their lives.
- "We still know very little about beluga whales, despite their immense popularity," said Dr.
Why this matters: new research or scientific developments with potential real-world impact.
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.
The findings suggest that both male and female belugas reproduce with multiple partners over the course of their lives. Researchers believe this behavior may help this relatively small and isolated population avoid inbreeding and preserve genetic diversity.
"We still know very little about beluga whales, despite their immense popularity," said Dr. Greg O'Corry-Crowe of Florida Atlantic University, lead author of the paper in Frontiers in Marine Science. "The primary reason for this is the difficulty of studying a species that lives beneath the waves in the cold and often frozen north. But this is the challenge that makes discovery, when it happens, more exciting."
