An amazing glass squid. When I disturbed it it would tuck in its tentacles and eyes, and even its fins and show big spots. So cool. The area around the brain was brightly iridescent. There are very faint long tubercles around the mantle if that helps with species id.
Really hard to get nice shots with a compact camera sadly.

Another one that looks like https://inaturalist.nz/observations/161763505. I'm only uploading the duplicates because of the uncertainty about what these are and hoping that the different views of different animals might eventually help with an ID. Assuming they are gastropods at this stage while recognising that they may not be.

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.

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!
