| Experts analysed thousands of sightings and photographs from the south west of England between 2007 and 2016. They identified 98 individual bottlenose dolphins and were able to define a distinct group of 28 that were resident throughout the year. | Experts analysed thousands of sightings and photographs from the south west of England between 2007 and 2016.

| Bottlenose dolphins can be recognised by their dorsal fin, which has a distinctive shape and markings. A dorsal fin is as unique to an individual dolphin as a fingerprint is to a human. The trailing edge of the fin is most commonly used to identify a dolphin as it is the most distinguishable area. This is because it is susceptible to tearing and, once torn, the tissue does not regenerate, causing permanent notches. | Bottlenose dolphins can be recognised by their dorsal fin, which has a distinctive shape and markings.

| Conservationists say the discovery could have implications for the conservation of the dolphins, who currently receive no specific protection in their home range. Dolphins are a wide-ranging species, with strong evidence needed to show that an area is important before protection can be considered. | Conservationists say the discovery could have implications for the conservation of the dolphins, who currently receive no specific protection in their home range.

| “Highlighting the existence of a resident population is the first step in seeking specific protection for these animals, with the next step being to collect more evidence on their movements and behaviour and strengthen the case for the importance of this area.” | “Highlighting the existence of a resident population is the first step in seeking specific protection for these animals, with the next step being to collect more evidence on their movements and behaviour and strengthen the case for the importance of this area.” |
