The following resources provide a comprehensive reference of the most recognisable CRRU study animals (identified from their "natural" dorsal edge markings) using the outer southern Moray Firth coastline, as recorded by the research team since 1997.

Some individuals may not have been seen for many years and their present status remains unknown. Others are recorded regularly and have been tracked over several decades.

All data and images remain the property of CRRU and any requests to reproduce these records should be made in writing to [email protected].
