The otter shake isn't a new milkshake on a menu.  It is a funny little dance that otters do when they poop.  Who knew they like to shake their booty. Here is, not one, but two otters doing the booty shake as they poop on a rock.  Now you know this little known observation about otters.

The Otter study and the Otter Spotter program is a project of Woodland Park Zoo's Living Northwest.  If you find any signs of river otters on Washington’s rivers visit the Otter Spotter and fill out the quick form on where and when you sighted the sign.
