Killer Seals Attack Dolphins: Swimmers Next?
6 Apr
Summary
- Grey seals are increasingly attacking dolphins and porpoises.
- Seal bites can cause severe infections requiring amputation.
- Experts fear this behavior may spread among seals.

Recent weeks have seen a disturbing increase in grey seal attacks on dolphins and porpoises in UK waters, with some incidents captured on camera. A grey seal was filmed gripping a common dolphin in the Irish Sea, and a similar attack was recorded off the coast of Wales. These occurrences have raised alarms among wildlife agencies and the public.
Experts highlight the severe health risks associated with grey seal bites, noting that the bacteria on their teeth can lead to infections requiring amputations. There are approximately 120,000 grey seals along the British coast. While this behavior appears limited to specific individuals, there is concern that it may be learned and spread among the seal population.
