Acipenser sturio [The Sturgeon].
Rare. One has been taken in a salmon net.
Scyllium canicula [The Small Spotted Dog-fish].
Found occasionally.
Galeus vulgaris [The Tope].
I am only aware of two instances in which this fish has been found within our limits: the one near Buckie, the other in the bay of Banff.
Acanthias vulgaris [The Picked Dog-fish].
Plentiful; often too much so.
Scymnus borealis [The Greenland Shark].
In May 1849 a large specimen of the above shark was captured by some fishermen belonging to Pennan, off Troup Head. When brought on shore, it measured thirteen feet nine inches in length, and eleven feet in circumference where thickest.
