Thought it might be interesting to see what comes up. OK I'll start....
First was a reef shark (hard to see) and a turtle. I was helping with some experiments on nesting bird counts and noticed them later.
Second was a fish surfing while videoing my friends surf kayaking
Third. I did not realise how low I was till I watched the video. The day was very windy and the drone was changing altitude more than usual.
