The Sweet Story of Otters and Their Favorite Stones

Otters are already among the most charming animals on Earth, known for their playful behavior, agile swimming, and expressive whiskered faces. But one of their most endearing habits is something many people don’t know about: otters often carry a favorite stone with them throughout their lives.

A Special Pocket for a Special Stone

Otters have a small pouch of loose skin under their forearms, sometimes referred to as a “pocket.” This unique feature allows them to tuck away a rock they’ve chosen as their favorite. Unlike most tools in the animal kingdom, these stones aren’t just practical — they often hold sentimental value for the otter.

Tools and Treasures

For sea otters especially, rocks serve an important purpose. They use them as tools to crack open hard-shelled prey like clams, mussels, and sea urchins. An otter will float on its back, place a rock on its belly, and skillfully smash a shellfish against it until it breaks open. But what’s fascinating is that many otters will hold on to a particular stone for years.

To them, the rock isn’t just a tool — it becomes a companion. Otters have been observed juggling their stones, playing with them in the water, and even clutching them close while they sleep, much like a child with a cherished toy.

A Glimpse Into Animal Emotions

Scientists believe this behavior shows not only the intelligence of otters but also the emotional depth of their relationship with objects. While other animals are known to use tools, otters stand out for forming bonds with them, giving us a heartwarming reminder of the softer side of nature.

Nature’s Little Surprise

The idea of an otter swimming, cracking shells, or drifting off to sleep with its favorite rock tucked in its pocket is almost too sweet to believe — yet it’s true. It’s one of the many small wonders of the natural world that makes us pause and smile.

Otters remind us that sometimes, it’s the little things — even a stone — that bring comfort, joy, and companionship.
