Dolphins' Bonds Slow Aging

The study of Indo-Pacific bottlenose dolphins in Shark Bay, Australia, finds strong social bonds among male dolphins may slow aging.
Closer friendships correlate with younger biological ages, about 1.7 years younger per standard deviation increase in bond strength.
Spending time in larger groups is linked to faster aging, indicating friendship quality matters more than quantity.
The findings align with human research and imply social relationships influence aging across species.

Dolphins and Orcas Collaborate

A new study shows Pacific white-sided dolphins and Northern Resident killer whales cooperate to hunt Chinook salmon.
Researchers documented the cooperation with drone and underwater footage that showed orcas following dolphins to locate prey.
Dolphins receive leftover fish scraps and protection from other orca pods, as experts debate who initiates these interactions.
The study challenges the idea that dolphins merely steal from orcas, indicating a more complex interspecies relationship.
