HEY HELP my mum got this video down on the beach this morning and we have no idea what it is. After many reverse searches, I’ve determined it to be a Dosima fascicularis. BUT Dosima have tentacle-like things.

Maybe it’s just holding it’s tentacles close together but I don’t know! So if anyone has any other ideas hmu.

The graptolites of Abereiddy Bay

Graptolites are curious fossils that are common in Lower Palaeozoic rocks where other types of fossils are lacking. The word ‘graptolite’ comes from Greek words that mean ‘writing’ (graptos) and ‘stone’ (lithos), and refer to the fact that graptolite fossils look like pencil marks on stone, partly because they’re flat and partly because of the iridescence of many specimens when freshly exposed.…

Buoy Barnacle (Dosima fascicularis)

...a species of lepadid goose barnacle that boasts a cosmopolitan distribution, with a preference for temperate seas. True to its common name adult D. fascicularis will hang downwards from the water surface, held up by a float, and is carried along by currents filter feeding along the way. Larval D. fascicularis are planktonic and must attach to a float (usually flotsam) for metamorphosis into the adult form. However, the adults are eventually capable of using their own float, and are usually seen in aggregations of many individuals all using the same float.

Dosima fascicularis was formerly placed in the genus Lepas but is now placed in its own monotypic genus Dosima. Dosima is distinguished from Lepas by the exceptional brittleness of its exoskeleton and by the form of the carina.
