Tursiops truncatus (Bottle-nose Dolphin)  

In Hebridean waters bottle-nose dolphins are at the northern extreme of their range. They are most frequently seen in inshore waters, close to the coastline around headlands and bays. There is a population of 30 to 40 animals resident in the Inner Hebrides (Kintyre to Skye) and a separate group of about 12 animals in and around the Sound of Barra.
