Orcas Smash Sunfish into Pieces with High-Speed Ramming

Topic: Biology

Scientists in Mexico's Gulf of California observed orcas using a new hunting technique. They smash dead sunfish at high speed to break them into smaller pieces, making it easier for young orcas to eat. This behavior has never been seen before.

Orcas are known as one of the ocean's smartest and most powerful predators. They have many ways of working together to catch their prey. Recently, scientists in Mexico's Gulf of California observed a new way that orcas hunt. They call it 'ramming.'

The researchers watched two separate events where orcas used this technique. In one event, a female orca held the sunfish with her large tail fin while another male orca charged towards them at high speed. The force of the collision broke the fish's tissue into tiny pieces.

The scientists think that orcas might use ramming to help their young eat more easily. They also believe it could be a way for orcas to play and have fun. But they're not sure yet, as they need to study this behavior further.

The sunfish they were hunting can grow up to 3 meters long and weigh as much as 2,000 kg. These fish often swim close to the surface of the water, which makes them easy prey for orcas. In fact, sunfish are one of the most common animals that orcas eat in this area.

The researchers recorded two events where orcas used ramming to break apart a dead sunfish. The first event happened in July 2024 and was observed by Dr. Kathryn Ayres from Beneath The Waves, a non-profit organization that works to protect the ocean. The second event took place in September 2025 and was filmed by Héctor Franz.

The scientists believe that ramming could be an important way for orcas to process their food. When the sunfish's tissue breaks apart, it releases tiny particles into the water that can change its nutrient composition.

Why It Matters

This discovery is important because it shows us how intelligent and adaptable orcas are in the ocean. It also helps us understand how orcas hunt and feed on their prey, which can inform conservation efforts to protect these amazing creatures.
