Thousands of these marine worms—called fat innkeeper worms, or “penis fish”—were found on Drake’s Beach last week! These phallic organisms are quite common along the West coast of North America, but they spend their whole lives in U-shaped burrows under the sand, so few beach-goers are aware of their existence. A recent storm in Northern California brought strong waves that washed away several feet of sand from the inter-tidal zone, leaving all these fat innkeeper worms exposed on the surface.

Next time you go to the beach, just think about the hundreds of 10-inch, pink sausages wiggling around just a few feet under the sand.
