I just learned about #InverteFest and this nudibranch seems festive enough for the occasion.

With all of the ant-science news I needed a cleanse - so I give you a White-lined Dirona or Alabaster nudi (Dirona albolineata) from Salish Sea. Taken during down time while doing work on federally funded research grant.
A white-lined dirona (Dirona albolineata) hunting for small snails along the sea bottom. The dirona, a type of nudibranchis a translucent grey-white color with a bold opaque white on the edges of multiple triangular leaf like cerata (a projection of tissue used for respiration/gas exchange, that also often have extensions of the digestive system in their lower portions). This particular species is usually found on rocky bottoms, occasionally mud, and feeds on small marine snails, anemones, tunicates and bryozoans. They can occasionally be found with pale purple or pale salmon tissue color instead of grey-white, but always have the bold white stripe.

I had so much fun tidepooling with @kellybrenner.bsky.social and learned a ton, like that this white-lined dirona nudibranch is peach-colored from eating sea pens! #invertefest

It's Golden dirona season here in the Salish Sea! These large sea slugs can be found without scuba gear if you search docks and pilings. #Nudivember

Decided to do a shake out scuba dive last night to try out a bit of new gear. I brought my camera, and grabbed some of my favorite nudibranch photos ever! (Also shrimp and fish are good)
An orange and white tipped nudibranch, Antiopella fusca, photograph against very dark kelp. It looks like a floating blob of translucent bulbs. White lined dirona nudi, Dirona albolineata, looking majestic against a dark background. Shriiiiimp. A Pandalus danae/ dock shrimp looking like it’s posing for the camera A gunnel looking cool. Maybe a crescent gunnel/ Pholis laeta. They are not eels, just long fish. This sorta thing matters.

Couldn’t sleep last night so I designed a white lined Dirona beanie and stayed up til it was finished and out of the wash.

Side by side of a white lined dirona 3D sculptural embroidered sea slug on a black beanie and a photo of the same species of nudibranch. The beanie has numerous cerata that are all connected at the base like the real animal and posable and movable. The rhinophores have fluffy white fabric at the ends and also stand up.

I went on a little walk looking for slugs today and just as I was walking back sad that I hadn’t seen any, I found this chonky Dirona albolineata I’d managed to miss on my way down.

Species #8 was White-line Dirona (Dirona albolineata), featuring two color variations from eating the orange sea pens. Plus one with a commensal scaleworm friend.

Every time I post something negative I feel like I should counter it with something nice. So here's a golden dirona nudibranch for you.

I spent the morning diving in the Hood Canal and got a pretty decent shot of this beautiful golden dirona. Biggest one I've ever seen, at least as big as my palm.

White Lined Dironas are popular here in the PNW, but they never get old to photograph!

White lined dirona

These guys feed on hydroids, bryozoans, crustaceans, ascidians, and snails.

This Golden Dirona made an #InverteFest appearance at the fuel dock. How spectacular!
