Just back from a weekend attending the Nordic Photo event in Gulen as a guest speaker. Alex Mustard and Christian Skauge did the workshop organized by Lars Stenholt Kirkegaard of Fotografit. I grabbed the opportunity to dive the house-reef as much as I could testing the new Sola 600 aiming lights (more on that to come).

Worm Aphroditoidea ssp. on crinoid Antedon petasus.

As always it's great to catch up with old and new friends at these types of events.   However, arriving on Friday afternoon at the end of the diving week, I was soon looking through the images shot on the preceding days. Amongst them was a shot of a rare hydro-medusae, that apparently everyone had shot and which I haven't seen since 2001.  And of course I had no decent pictures from that lucky encounter.   My plans of spending a lot of time socializing went straight out the window and I ended up spending most of Saturday under water.  After an hour or so and I had located and photographed the hydro-medusae, but the house reef had more to offer. Finally after countless crinoids in many a fjord here in western Norway, I finally found a crinoid shrimp, the first I have seen - and the first I have ever heard of in Norway!

But it didn't stop there. I also found two worms on the arms of a crinoid. What the worms did there, parasitic, commensal perhaps? I don't know, but interesting for sure and as always the house reef at Gulen dive resort once again coughs up rarities for us photographers.
