New study shows that beluga whales in the Arctic can form longterm social bonds with both kin and non-kin, mirroring the social complexity of humans
- Researchers from Florida Atlantic University studied beluga whales in the Arctic
- They found surprising diversity in the way the whales socialized
- Unlike killer whales, belugas aren’t primarily driven by matrilineal kin relations
- Belugas move in groups ranging from two to 2,000 with kin and non-kin
New research suggests that beluga whales form complicated and longterm social bonds that include both kin and non-kin relationships, which mirrors the complexity of human social habits.
A team of researchers from Florida Atlantic University studied the movements and behavior of beluga whales across 10 different locations in the Arctic.

They found that unlike killer whales, which tend to socialize along matrilineal lines, beluga whales frequently mix in large and diverse groups that often extend far beyond simple kinship.

Researchers from Florida Atlantic University studied beluga whale social habits and found significant diversity and complexity
‘Unlike killer and pilot whales, and like some human societies, beluga whales don’t solely or even primarily interact and associate with close kin,’ Florida Atlantic’s Greg O’Corry-Crowe told Florida Atlantic’s news blog.
‘Across a wide variety of habitats and among both migratory and resident populations, they form communities of individuals of all ages and both sexes that regularly number in the hundreds and possibly the thousands.’
‘It may be that their highly developed vocal communication enables them to remain in regular acoustic contact with close relatives even when not associating together.’
The team studied the whales at locations in Alaska, Canada, Norway, and Russia, tracking groups that ranged in size from two to more than 2,000.
The team took mtDNA readings from the whales to identify the lineage of each, which often revealed complex social groupings.
These groups could be extraordinarily diverse, with some composed of single sex whales of similar age, while others were both mixed age, mixed sex, and mixed kin groups.
Unlike killer whales and other species that tend to group according to matrilineal bonds, beluga whales often traveled in groups from a variety of different lineages

‘This variation suggests a fission–fusion society where group composition and size are context-specific, but it may also reflect a more rigid multi-level society comprised of stable social units that regularly coalesce and separate,’ O’Corry-Crowe said.
‘The role kinship plays in these groupings has been largely unknown.’
The team says these wide-ranging social bonds could also be key to how beluga whales will adapt to increasing changes to their natural habitat brought on by climate change, which they hope future research could document.
‘This new understanding of why individuals may form social groups, even with non-relatives, will hopefully promote new research on what constitutes species resilience and how species like the beluga whale can respond to emerging threats including climate change,’ O’Corry-Crowe said.
