Anyone able to tell me what these are? Last year they were black and scattered over local beaches. This year blue, but again washing up. They’re tubular. Presume washing in from fishing boats, but what for and why? They look new/unused.
(Painted topshells just for show)

Life is constant learning, which is a joy, but not sure this extends to social media platforms. How does this work?
Here’s a photo #firstpost of a gem sea anemone (Aulactinia verrucosa) to get things started.
