A fun detective puzzle for anyone wanting to dig further to species (and I'm not certain of genus, but it seems plausible). Thank you Smithsonian for the first photo in this slideshow ("Tiny Paddles": https://ocean.si.edu/ocean-life/invertebrates/hyper-eyes-hyperiids-how-some-shrimp-creatures-see-light-deep-sea
I found three of these alive inside a live salp, likely Cyclosalpa affinis (separate observation: https://www.inaturalist.org/observations/186620626) drifting in a marina. They refused to leave the comfort of their salp, so these aren't the finest photos, but I did get some exceptionally mediocre video too.

I think I see one in my other Cyclosalpa affinis observation too, although its too distant to tell (photo from boat): https://www.inaturalist.org/observations/99683938

Catriona colombiana was located on sandy substrate at a depth of 50 feet. Length was 1 cm. Water temperature was 57* degrees F.
Note that a different measuring device was used for water temperature. This device was calibrated and found to provide a true measurement, so it is not necessary to add 4 degrees to find the true temperature as with my other observations. See my notes for details.

@imlichentoday Do these little creatures look familiar? They are on alot of the Cadlinas I am seeing over the past month. Are they parasitic or simply associated with the host?
