Several unusual creatures washed up on Tide Pool Beach at The Sea Ranch recently, discovered by the Sarkisian family of Portland, Oregon. Christy Sarkisian wrote, “There were several sea-looking centipedes that washed up on July 3rd. In 20 years of coming to Sea Ranch we have never seen anything like it. They were like a centipede with thousands of legs, but on the side of their bodies, wiggling. They were unable to really move on the sand at all.

“They were green in color and light red on their undersides. Of the four that washed up, they varied in size from 12 to 36 inches, all curled up. One rode the tide out, and seemed to swim away like an eel.”

Local diver Eric Anderson knew they were worms, guessing Clam worms. Carol Preston of NOAA believes they were Mussel worms, Nereis vexillosa. She wrote, “I have seen them a few times, but not often. They can get quite big, and they mainly feed on other worms.”

Thanks to Christy for allowing me to share her photos with you here. It's fun to learn more about the fascinating creatures that live in the ocean.
