Kalifornijsko obalo poplavilo na tisoče "penisov" #foto

Živijo pod peskom

Znanstveno ime živali, ki jih je naplavilo na obalo Drake, ta leži približno 80 kilometrov severno od San Francisca, je Urechis unicinctus, spadajo pa pod deblo kolobarnikov in so vrsta črvov. 

Omenjene živali sicer živijo zakopane pod debelo plastjo morskega peska, zato so najverjetnejša razlaga za pravo poplavo "penisov" ob obali nedavne nevihte, ki so zajele to območje. Padavine so s seboj prinesle močne valove, ti pa so s svojim delovanjem sprali nekaj metrov peska in razkrili te morske črve. 

Tovrstni morski organizmi pa so precej pogost pojav na zahodni obali Severne Amerike, le da jih prebivalci redkokdaj opazijo, ker živali živijo v grapah pod peskom.

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. 🙃 . .
