Photo ID Catalogue

The Shannon estuary is home to resident bottlenose dolphins, meaning the same individual dolphins are present throughout the year. How do we know ?

Bottlenose dolphins tend to acquire scars and marks on their dorsal fin and upper part of the body, possibly through aggression and/or socialising. In some cases these marks are so unique that the individual dolphin can be recognised from them. The photo-identification (photo-ID) technique takes advantage of these unique marks.

Individual recognition of dolphins can be used to study the movements, habitat preference and residency of individual dolphins as well as their social behaviour and associations and can be used for monitoring purposes. Read more...

If you have taken photographs of bottlenose dolphins in the Shannon estuary or adjacent waters, see if you can find the dolphin in the ID catalogue and let us know the results of your search.
