Tonna attacking Stichopus sea cucumber at night. As he extended his proboscis around the sea cucumber, the cucumber shed its skin on two sides of its body and slipped away, releasing its grip on the bottom and floating away in the surge. The Tonna was left with two flaps of tough skin that it did not eat (second photo).

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
