This appendicularian (Oikopleura sp.) looks stunning bathed in Lugol’s iodine solution. It got caught up in my phytoplankton subsample, but I love the way it highlights some of the organs in the trunk (the bit that looks like a head).

Greetings fellow chordates!
Here’s an Oikopleura and it’s absolutely stunning snot house.
Saw so many of them yesterday night.
(I really need to bring my actual camera out with me sometime)

Revisiting pics because there was lightning tonight so I also couldn’t go out looking for critters. Appreciate these Oikopleura
Some Oikopleura pics from a few nights ago since winds were a bit too much to go looking tonight.
