Mr MacPherson, 24, told BBC that he noticed the otter "jumping about the road". "I nearly hit him with my car so I pulled to a stop, got out and it was still there and I tried to get closer. I don't know what made it go a little bit crazy," he told BBC. He also added that it had huge teeth and was biting his feet. His boots luckily saved him.
The video shows Mr MacPherson walking towards the otter with his camera ready. After noticing Mr MacPherson, the otter can be seen biting his shoe. Mr MacPherson can then be seen running away from the animal. The otter seems really persistent - was it really angry or just wanted to play with Mr MacPherson, who knows.
"Seen a wild otter today...I am not sure I like otters anymore!" he says on Facebook.
"Just wanted to be your friend, Rory!" says one commenter on the video. "LOL! Either young and trying to figure out what you are or guarding young. Either way, you're lucky to have seen it even though you may not feel that lucky," says another.
