Hydroid Carmophyra nutans floating about...

[Norseman]

We wound a couple of these hydroids on a sandy part of the bottom. Erik was excited since he hadn't seen any before (And I was all cuz I've seen'em at least once before )



They're the Carmophyra nutans discussed in a previous thread (but with the wrong heading which can't be changed so I started a new one)

It could have been Erik's eager finning that did it (not mine, obviously ) but following the current we came across this guy twitching and turning in the water.
Perhaps this is how they move around? With non retractable tentacles and that short "root" it shouldn't take much of a current or sand-shifting before they're torn loose from the bottom even without Erik's buoyancy issues.
I couldn't be bothered removing all that silt from the pic, but you get the idea anyway.
