Harbour Porpoise in Arbroath Harbour

The first time I've ever seen a Harbour Porpoise in the outer harbour at Arbroath. It's possible the animal was injured or weak and a mark on its flank looks like it could be a propeller injury, lets hope nothing is actually wrong with it. I'll have a look again on Monday.

Photo taken at sunset and enhanced to reveal the mark on its side, this only shows half of the Porpoise from head to dorsal fin.
