Killer whales sink another boat off the coast of Spain — why are they still doing this after 6 years?
Live Science · 2026-07-28
A recent incident off the coast of Spain saw killer whales sink another boat, continuing a pattern of behavior observed over the past six years. These interactions, predominantly involving Orca Group, or "Gladis," with sub-adult males between 6 and 14 years old, remain a subject of intense scientific scrutiny. The incidents, which started in May 2020, have primarily occurred in the Strait of Gibraltar and along the Iberian Peninsula, targeting sailing vessels and, less frequently, motorboats. While the precise motivation is still debated, leading theories include playful or exploratory behavior, a stress response to human activity such as fishing, or a form of social learning where behaviors are mimicked within the pod. Despite the repeated occurrences and the damage inflicted, there have been no confirmed fatalities to humans, though the encounters pose a significant risk to mariners.
