River Otter This River Otter is here to remind you to have a safe and happy holiday! If you are interested in viewing river otters, winter is a great time because they tend to be more active during the day, making them easier to spot. While this water would be too chilly for most of us, river otters are quite at home due to their thick insulating fur, dipping into the water to hunt for fish, crawfish, and even hibernating frogs. This guy posed for me for roughly 5 seconds before he was back in the water looking for trouble!
