Researchers have released a video about basking sharks shoaling in large numbers off Scotland's coast last year.
Scottish Natural Heritage (SNH), the University of Exeter and researcher Colin Speedie have been examining 'hot spots' for the sharks.
In a newly-released video publicising the work, Speedie said shoals of 73 fish were counted off Coll. A shoal of 50 fish were also recorded around Hyskeir, a group of rocky islets near Canna.
The video shows courtship activity including sharks breaching.
In Scotland, the fish were hunted until 1994. Numbers of the sharks were so low they were given protected status in 1998.
Speedie said historic records of where the sharks were hunted could provide clues to other hot spots.
