Shark in Donegal Bay

Last week (calm sea) when pollocking in Donegal bay from a rock shelf I saw a shark (classic dorsal and tail fin) close in (could have spit at it) - just cruising along the rocks. Any idea what it might have been?

Was it a good size :?:

Basking shark at a guess :?

prob a basking shark ,there's been a fair amount spotted around the donegal coast so far this year .
