Info from Licensor: "I took this video of an echidna swimming on the third of October, which was a reasonably hot day. I was about to go for a swim when the cows walked out of the river. When I looked towards the river again, I noticed a small animal swimming, and as I got closer, I saw it was an echidna. As a seasoned Aussie and country liver, that is something I have never seen in my life!"
