For lo, I have found something new on the beach this year. Every year, new things wash up. This year, it's those particularly long, pointy shells, pale ivory/pink, 3/4" long, and...these things!
At first I thought it might be frayed plastic, but it seemed made of clear tubes only. Eventually I realized it was... formerly alive. Either in-and-of-itself, or as the innards of some heretofore-unknown-to-me sea creature. A seaweed?
It got nothing for its troubles.
I kept going after a while.
I found bigger bits of the clear seaweedy stuff, suffused with grains of sand.
One small beached jellyfish today.
