Goniodoris sp. This one an adult with eggs. Approx 25mm long. Tried a few angles but no better high profile. @drmattnimbs @clinton @jpsilva castenea? nodosa? meracula? Thanks Richard
4 juvenile Goniodoris sp. seen 16th and 18th January on host purple/yellow Botrylloides. The first one has rotated inside its "pit" in the ascidian between 16th and 18th Jan. Size 2.5- 3mm except for fourth photo slightly bigger at 4mm. Suspected adult and egg mass is as per my post 25 Mar 2021 (and another juvenile 18 Mar 21) Depth 5m. Several other individuals noted but difficult to photo.
possibly juvenile Goniodoris sp. Size 2 to 3mm, Depth 3m, in association with ascidian Botrylloides sp.
Just saw this one floating around. It then landed on some seaweed.
Not many other nudibranchs around. Just a few gold margineds.
Searched all over but just one at the good reef wall. Might even be the same individual I saw a month ago! Now even more spectacular fully grown.
I noticed when a fish attacked it or I nudged it, the slug would extend all its cerata out into a spike ball.
~3.5 cm long
~3 m subtidal
Just one. I have it in my aquarium, but there seems to be no change of papillae shape. Lots of tests based on water flow, being squashed under a rock etc. It is not negatively phototaxic so it is hard to test for it crawling under a rock. Even when first found the papillae were spiky.
Overnight it made its way to the underside of the rock but didn't squeeze in and the papillae were still spiky.
Very happy to find this one. Similar to some found under rocks up north. I wonder how much the environment affects their morphology.
Under a large rock on small cobbles. The same rock as the Janolus aff. hyalinus.
~1cm long
Shallow subtidal
The annual find for me. Hope there's more sooner than that!
Just saw the one.
~1.2cm long
~2m subtidal
Just saw one.
Also saw a few T. flemingi, many large gold margineds, and a Trapania rudmani which was floating in the water near a reef wall far out.
Rare at this spot. At the far reef.
~1.5cm long
~3m subtidal
Two tiny ones on a fittingly small Catenicellidae bryozoan bush.
At the far reef.
~5mm long
~1m subtidal
Not previously recorded in Dunedin area to our knowledge. Two specimens sighted 30mm and 25mm, depth 15m
Bifurcated right hand side rhinophore. Depth 4m. Length 12mm
similar to previous sightings as per posts 23May23, 4May23. Length 4mm
Unusual to see during daytime. Under jetty so low light. Depth 3m. Quite a lot of separate egg masses on jetty piles.
Depth 5m, length ~40mm, see also 11 Dec 2020 https://inaturalist.nz/observations/66385499
First photo is with my gloved index finger for some sense of scale. Curious to know collective thoughts on what the other orange with white spicules might be. Juvenile Coryphellina ? Hydroid gonophores although the orange and white things are quite a bit bigger than the hydroid polyps, something else? These photos are of two individual Coryphellina from two locations several metres apart but both locations have these associated orange/white objects.
