I was doing some short test videos out by a river in a park. It had rained in the last 48 hours. Every now and then it smelled a bit bad. I just went about my project. It took about 1/2 hour. As I was packing up to leave, I looked down near where my left foot had been for the whole time, and this was there. I think it had been a salmon at some point last week. The bottle is about 134mm long.
