Does anyone recognize this- or know someone who might? I’m insanely curious about what it actually is. I found it on the beach yesterday, and it’s pretty unusual- most marine debris on this beach is along the lines of plastic bags, sunglasses, hats, shoes, kids toys, and food/drink packaging with the occasional bits of fishing or crabbing kit. This does not appear to fall into any of those categories. I’ve appealed to Twitter, but so far, nada. Thoughts?
