Otter

We had a lovely surprise when we went for a walk down by the river Nith at lunchtime. One of the town otters was about hunting lamprey. Sometimes catching 2 at a time and swimming to the side to eat them. We could not believe either how effective a hunter they were or the amount of lamprey they managed to eat. We read later that otters need to eat a quarter of their body weight a day to stay warm. They have a fast metabolism.
