Over a number of years, the actions of fishermen and sea anglers have attracted the attention of marine scientists at the Dunstaffnage Marine Laboratory who quickly became aware of these fishers catching spurdogs in the Loch Etive area near Oban on the west coast of Scotland. These small sharks were always on a catch-and-release scheme, and the researchers thought that this little British shark deserved a bit more interest in order to discover what they were up to, trying to learn more about their habitat and habits, and why Loch Etive was so important to the Scottish population of these fascinating sharks.
