Every winter around this time of year, large groups of bottlenose dolphins congregate in the waters between the Isle of Man and North Wales. 2012 is no exception with groups of between 20 and 100 animals spotted in this area since the end of October. More on the sightings on our recent sightings page and in this BBC report.
Using a technique called photo-ID ( where animals are identified using nicks, notches, and markings on their dorsal fin) Sea Watch Foundation and the Manx Whale and Dolphin Group have been able to prove that some of these animals come from Cardigan Bay having traveled over 200 km. This is a great example of how this completely non-invasive technique can give us valuable insight into the way in which bottlenose dolphins use their habitat throughout the year. This type of information is crucial when setting up protected areas and monitoring their effectiveness.
