Hi @joe_fish Suspect this is 'Actinia sp.' also known as Paterson Inlet anemone Steve de C. Cook, Invertebrates 1, page 164. Photo credits to Tom Bliss as I had the close-up lens on and too big. Certainly is quite large given the 150mm scale ruler placed at side. Depth 6m, clean sand substrate, strong current area. Also @chicky67 to look at on return!

Never seen anything like this before.

In a sea cave in a rock pool that would be close to the high tide mark. The rock pool has water in. This area was dark and these were only spotted when shining a torch around the cave.

When the tide comes in it would pound in, with the water being turbulant as this is on the west coast where a calm day is meter high waves and anything lower is a rare event.

The closest these remind me of is a wandering sea anemone, but I don't think they wander into caves, climb up the walls and find a nice rock pool to rest in.

These three where the only ones seen. Photo taken with the torch shining on them

I cannot BELIEVE I actually found a name for this crazy little bivalve.
My reaction upon seeing it was definitely this:

I started out with looking at local iNat sightings but of course that didn't help because there isn't a single sighting of this thing. So off to ALA I went trawling through families, and I'm so very glad I stopped to look closer at the holotype photo. Going by this link it would seem that Maoricardium is a usual host for Ciboticola, although that link (?mis)identifies it as Anadara pilula. The link above pretty clearly shows a dead bivalve, and I can't find any other images of it beyond one or two specimens, so perhaps this is the first live specimen.
