California beach taken over by strange worms resembling male genitalia

San Francisco: A northern California beach was host to a peculiar little subterranean creature following a bout of winter storms. Thousands of pink, throbbing phallus-looking creatures wound up along the beach about 80 kilometres north of San Francisco.

These 10 inches long pulsating creatures are called fat innkeeper
worms and are colloquially referred to as the ‘penis fish’ due to their acute similarity to the male genital. They burrow deep under the beach’s sand and were left exposed after incessant waves swept away the layers.

SHOOK ? 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 beachgoers are aware of their existence. ⛈? A recent storm in Northern California brought strong waves that washed away several feet of sand from the intertidal 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. ? . .

The Korean name for this curious creature is gaebul, which translates as “dog dick.” Here in the States, it’s known as the fat innkeeper worm or the penis fish. Its scientific binomial is Urechis caupo, or “viper tail tradesman.” Whatever you call the animal, you can find them in abundance at Bodega Bay, where they build burrows in the tidal mud flats. On Saturday afternoon, our small, but enthusiastic clamming/crabbing crew thrust shovels and shoulder-deep arms into that mud in pursuit of Pacific gaper clams (Tresus nuttallii), but we also pulled up at least twenty of these red rockets. We returned them to their subterranean homes – excepting those that were snatched by eager herring gulls. I learned later that the gulls were the smarter hunters; fat innkeepers are edible, and are even considered a delicacy in Korea. Still, even though we missed out on a prime opportunity to dine on dog dick, we had a successful, fun outing, encountering a number of curious species, some of which now reside my belly. ⊙ What you’re looking at here: • Fat innkeeper worm (Urechis caupo) • A ring of prominent setae on the butt end of the fat innkeeper worm (Urechis caupo) • Bay ghost shrimp (Neotrypaea californiensis) • Lewis’s moon snail (Euspira lewisii) • Bucket filled w/ Pacific gaper clams or “horsenecks” (Tresus nuttallii), white macoma or “sand clams” (Macoma secta), and Lewis’s moon snails • Red rock crabs (Cancer productus) back in the kitchen, icing after boiling ๑ ๑ ๑ ๑ ๑ #BodegaBay #gaebul #FatInnkeeperWorm #UrechisCaupo #BayGhostShrimp #NeotrypaeaCaliforniensis #LewissMoonSnail #EuspiraLewisii #PacificGgaperClam #TresusNuttallii #RedRockCrab #CancerProductus #crabbing #clamming #huntergatherer #SonomaCounty #California #naturalhistory
