A barnacle, yes, but not that one ( which isn’t found in Britain AFAIK).
Acorn barnacle
Which one? Of the common species I think only one is “Darwinian”!
Darwin described the titan acorn barnacle (Megabalanus coccopoma) and 8 more speies of Megabalanus. He named Balanus glandula, the giant acorn barnacle (Balanus nubilus and Balanus trigonus., as well as 5 species of Amphibalanus and Fistulobalanus pallidus.
And barnacles in other genera; the species originated in the Antipodes.
Let’s move on; Darwin described a species which originated in Australia and New Zealand; it became established here by being transported accidentally by shipping. It has been called the New Zealand Barnacle; for a long time it had been known as Elminius modestus; but the generic name has been changed recently. Dassie rat; feel free to set a question.

I knew that Darwin was interested in barnacles, but I didn't realise he described so many species.
Which animals produce roots, which tangle with roots of neighbours to produce 'ropes'? The ropes travel down tubes of dead neighbours and run through holes in rocks.

My first thought is the byssus threads of mussels, but they don’t fit all of your description. Time to think!

Hydroids?

What about Pterobranchs?

Vestimentiferans
Well done, Tetzoo Quizzer. You're right.
These giant tubeworms formed a phylum, Vestimentara until they joined beard worms (the former phylum Pogonophora) in a family, Siboglinidae, of polychate annelids. That is some fall from 2 phyla to 1 family.
Now it's your turn.

Now it's your turn.
Which marine invertebrate has a unique type of sex determination; if the larva settles by itself on the seabed it becomes a macroscopic female, but if it is swallowed by a female it becomes a microscopic parasitic male?
The green spoonworm (Bonellia viridis).
Thanks, Tetzoo Quizzer. This is a learning experience and it makes a change to mention phyla that rarely, if ever, are kept in zoos.
