Beautiful pics @Searcaigh I think your stiliger is actually a Costasiella sp. that feeds on Avrainvillea. They are often mistaken for each other. The Costasiella has close set eyes whereas the Stiliger has them set wider and behind the rhinophores.

Thanks for your feedback @Cali_diver

Cuthona sp. near Mcmurdo station, Antarctica.

near Mcmurdo station

That's awesome. I always love seeing that places like Antarctica, which look like barren ice deserts, have their own diversity of colorful marine life.

Still a costasiella sp. to me.

Some comments on your IDs :
- Headshield slug is Chelidonura varians
- Goniobranchus sp. is G.Collingwoodi
- I'm pretty sure the Hypselodoris infucata is in fact Hypselodoris roo (flat facing gills)
- No Hypselodoris maculosa for sure but something else I haven't recognized (Thorunna?)

Just found this thread!
After being on SB for years… and perfect timing.
I’m in Guam and finding plenty of nudibranch. I’m just beginning the quest for nudi knowledge and left my ID book at home. Anyone know what these are?

My dive buddy was kind enough to snap a few photos of these to help me identify them. I find ‘em, he shoots’em. All credit goes to him.

Unfortunately his flash flooded on this dive.

Image #1 is Halgerda tessellata I believe. Slight variation in peripheral edges of brachial plume without traditional darkened edges.

Several phyllidia species

Unsure if the first phyllidia is pustulosa vs nigra?

Then the phyllidia carlsonhoffi vs madangensis vs picta?

Do you ever use an UV filter or light?
I just read Nembrotha kubaryana has UV colors. That would be amazing to see.
