OT

This is a new dog otter. He looks quite young to me and he was acting quite apprehensively. 

He would shoot out of the water onto a rock - have a quick spraint then shoot back into the water - only to repeat the whole process several times more. 

He is definitely a new kid on the block and I think he is trying his luck and marking within pinknose's territory (the dog otter that I frequently have photos of) - sadly I couldn't hang around to see if there was going to be any fisticuffs!
