Check out how river otters get a long in the cold.

River otters do well in the cold. Texas A&M researchers found that they are internally warmed by thermogenic leak from their skeletal muscle, which in turn, elevates their metabolic rate keeping them warm in frigid waters and ice. We had some otters visit recently. Thank you Donald Parrott for sharing photos of this happy sighting.
