Basking sharks are the second largest fish in the world. They are also one of the most mysterious creatures in British waters, and huge gaps remain in our knowledge about the way they live. Despite this, the number of basking sharks does seem to be on the increase. They are now common visitors around Mull and Coll and other parts of the Western Isles during the summer, and are also being seen increasingly often off the Northern Isles.
On Sunday, The Observer featured a fascinating article about these huge, harmless fish, which you can read here. You can also visit the BBC page to find out more and see some wonderful footage of the sharks.
