## At a glance

- Orcas have been documented blowing sunfish to pieces in playful behavior.
- The sunfish were already dead, suggesting the whales may be playing or turning them into bite-sized chunks.
- Killer whales are known for their intelligence and complex social behaviors.

A new study documents killer whales blowing sunfish to bits in what appears to be playful behavior. The research, published in Frontiers in Ethology, offers unique insights into orca behavior. Video from Beneath The Waves shows orcas charging into sunfish, causing them to explode into pieces. The sunfish were already dead, suggesting the whales may be turning them into bite-sized chunks or simply playing. Orcas are known for their intelligence and complex social behaviors.

## Orca Behavior and Intelligence

Researcher Kathryn Ayres noted that orcas often tear apart prey and share it with other members of the group, including calves and juveniles. Mark Peter Simmonds, director of science at OceanCare, compared the behavior to human formal meals where socializing and nutrition are in play. Killer whales have been documented engaging in various playful and sophisticated behaviors, such as 'wave washing' to capture seals and using seaweed as tools for grooming.

## Implications of the Study

The study highlights the complex and intelligent nature of orcas. Rebecca Wellard, a scientist at Western Australia's Curtin University, hopes the findings will increase respect for these creatures. The research was conducted off the Gulf of California in 2024 and 2025.
