Goose Barnacle - Pelagic
[Lepas anatifera and similar species]
These Goose Barnacles attach to floating stuff on the high seas and depend on wave action to bring food to them. They're seen only when something they're attached to washes up on the shore. In an environment much less harsh than for intertidal species their stems are thinner. For these reasons they aren't much eaten. Photo © i0123.

There's not much to eat here, but if you must try, do the same as for Intertidal Goose Barnacles.
