Cool to see this species finally. I've been searching for quite a bit.
There were at least 7 or 8 within a large Amathia wilsoni bush. I always search through this exact bryozoan here so they may have just popped up. Eggs were also present. I also saw another individual on a separate bush.

~0.5-0.8cm long
~2 & 3m subtidal

This is my second one of these. There was also another one in the bag for this date but unfortunately it was broken. I'm very happy to have two good ones (sa https://inaturalist.nz/observations/151690092).
5mm grid.

First image: Athoracophorus bitentaculatus at rest, unaware of the fact that a flatworm is on its heels, following its mucus trail.

Second image: The flatworm has caught up with the slug and pounces on its prey. The slug shows a surprisingly quick reaction and immediately elongates its body in an attempt to escape, albeit at a sluggish pace. Which is a bit faster than I would have imagined.
And just when I thought the slug was done for, it pulled one out of the hat: the BASE-jumper move! Without parachute, it let itself fall off the tree into the leaf-litter below.
The flatworm looked left and right, seemingly confused by the sudden disappearance of its prey, then showed some superior intelligence. Applying some basic notions of physics, it reasoned that if it let itself fall off the tree also, it would land in exactly the same place. And so it did!
Upon landing in the leaf-litter on the forest floor however the flatworm appeared disoriented and was unable to locate the slug again. With that BASE-jumper move, the slug may have just pulled off the narrowest of all escapes!

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!

12m. The gastropod shell the limpets are on was only 30mm long so they are <10mm. Cellana stellifera from the depth (sub-tidal)?

Possibly a juvenile of the same species that I previously observed: https://inaturalist.nz/observations/100754895
But it does look a bit different.
This one was floating and landed on seaweed in the corner of my eye. At the surface but in quite deep water.

~1cm long
<1m Depth
