It's a River Otter

I had just taken a short break from work. I had lunch then I decide to go on a short  ride on my bike. Less than 5 minutes later, I turned to my left and saw something looking at me. Quickly, I stopped and got my camera out. I was able to take a couple of pictures before he dove into the water. He was definately a river otter? Do you remember "river otter" in Japanese? Of course you do. That was an exciting after lunch ride.

In case you forgot, otter is カワウソin Japanese.

"That's right! And don't you forget it!"
