Why Has a Group of Orcas Suddenly Started Attacking Boats?
Scientific AmericanMay 24, 2023
The Facts
A group of killer whales severely damaged a sailing boat off the coast of southern Spain on Thursday. This is the latest in a series of similar incidents in the waters near Spain and Portugal.
According to the research group Grupo Trabajo Orca Atlantica, which tracks populations of the Iberian sub-species of orca, the attack follows at least 20 interactions between Orcas and small vessels this May alone, in the Strait of Gibraltar.
The Spin
Narrative B
While these incidents may be worrying, the young whales may just be attracted to the boats and are conveying this behavior through complex social behavior. Orcas have not historically been known to be aggressive toward humans — even when they were being hunted and placed in captivity in earlier decades.
Narrative C
Killer whales are a species being stressed by climate change. Warming waters, changing food webs, and melting sea ice is pushing these magnificent creatures farther north, changing their diets and behavior. We must keep in mind greater environmental pressures when observing changes in one of the ocean's apex predators.
