There’s something about otters that’s inherently interesting. They’re like water-cats, but as playful as dogs.
If you’ve visited aquariums or zoos with a glass shebang that lets you see them, they’ll do games with you, racing from side to side. And there’s all kinds of footage of otters playing in the wild, sliding down mud hills or snow. I used to love monkeys as a kid, and hey, they’re still fun to watch, but the otters are the one animal who seem to just have a surplus of joy.
Also, they are crazy photogenic. There’s an entire site dedicated to photographs of otters, and they found this photo earlier and put it up. Because otters are just that cool.
