The otter is a creature of land and water, feminine elements. In both Native American and Celtic traditions, otter represents joy. She is the child within all humans.
The hallmark of otters is their playfulness. Both the adults and young ones frolic. They toss shells into the water, then dive after them. Otters slide down banks, head-first on their bellies. They float on their backs and chat with each other by chirping, and dive in and out of the water.
The video is called "Otters Holding Hands" and was quite a hit on YouTube when it made it's debut a couple of years ago. You may have seen it. Turns out the otters are not "holding hands" out of any affection for one another, it is a natural survival instinct so that when they float on the open river, they don't get separated from their group by the currents.
