Janolus ignisObservador
fun-gal-nzDescrição
We found 10 of these yesterday, so these are the best photos (of more than one).
This time they were on the sunny side of the seal colony, all awake and slithering around at 2-230 p.m. All probably within 10 metres of the sea in shallow rockpools, probably average depth of 10cm of water.
Average size 1cm.

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
