For a number of years, researchers have been aware that some individual grey seal males kill and feed on marine mammals (including grey seals, harbour seals, and harbour porpoises). This behaviour has been observed in the UK and overseas, but we don’t yet know how many individuals it involves and how often it occurs.
The new webpage provides an opportunity to report evidence of strange interactions between grey seals and marine mammals that may be related to this behaviour. Photographs and videos are particularly helpful as from these we can identify both individuals and species and gain an understanding into the regional extent.
This project is working closely with the strandings networks around the UK, and they are the first point of contact for reports of dead animals. Details of these are:
