When I was in California a couple of weeks ago, I visited Elkhorn Slough, one of my favorite spots between San Francisco and Monterey. This is an almost can’t miss location to observe sea otters — and almost always, they are in the water. It’s rare to catch one on land. I crawled over the sand very slowly and quite a distance to photograph this one. It didn’t seem bothered at all by my presence, and it even crept closer to me a couple of times as the tide rose. As you can see, unlike the river otters that I’ve been posting lately, sea otters generally have a much lighter head and neck than the rest of their body. They also happen to have the densest fur of any animal on earth.
