I used to complain about the seaweed on the beach, but not anymore. I have a deeper appreciation for all things on the beach, and love to explore the sand, rocks and everything else around me. When the winds and currents cause crazy waves, a lot of things get washed ashore, including sea creatures that are normally out in the open ocean. Last week, I found by-the-wind sailors after a windy day. I also discovered a few clear, hard tube-like things amongst the sea grass and kelp on the sand. I thought that a fisherman dropped some lures behind, because the tubes did not have tentacles, were not squishy, and were not moving.
After visiting Dana Point yesterday, I found even more of these oddities on the sand, just out of the intertidal zone. The tube-like creatures at Dana Point were slightly larger, and some were more pink or orange than the ones up at Crystal Cove. Now I knew that these things had to be more than fake fishing lures after seeing them at two different beaches.
Of course curiosity got the best of me, and I am a science nerd after all, so I did a little research online after my latest beach visit. It turns out these little tubes are actually animals called sea pickles!
Sea Pickles actually house a colony of organisms, known as zooids. They are filter-feeders and float by the hundreds in the open ocean, filtering phytoplankton through the tube “house”. When the water temperatures rise and the winds and/or currents change, it is believed that these creatures can be swept onto the shoreline. Every once in a while, sea pickles can be found amongst the other debris washed up onto the beach…which just supports my belief that it pays to look closely at everything when at the beach!
