Freshwater aquatic insects in running creek. This insect was living in a tube with 5 prongs, connected by a web of mucus/silk which it used to catch particles in the water. I watch it actively eat the webbing and create new webbing. There were about 5 active ones on a rock, they were about 1cm tall.

Inside Halichondria sp. Looks like L. alata but extended process on article 5 on Gnathopod 2 is longer than average and dactyl has interior bump with setae. Gnathopod 1 dactyl minute with long setae, article 2 curves steeply. Coxae deeper than wider with numerous bumps. Stridulation ventral coxal plates. Rostrum more prominent with longer antenna. Antennae 1 with 16 segments and minute accessory flagellum. Eyes with >20 ommatidia

G1 dactyl shorter than article 3 Male has maxillapede instead of keel.

Only about 2-3 mm. Cerrata were green with cream tips, and the head was yellowish between the rhinophores. Mcduck pointed out that no oral tentacles were visible (pointing ID to T. adspersa). Body was blotchy cream and brown. Longish, mostly-clear tail contracted as it moved; see video: https://flic.kr/p/XfaDk2
Note that the truly miniscule photobomb nudibranch (maybe a juvenile) is paler and has a T. adspersa-like semicircular oral veil.
Location: T. adspersa is an esturine/brackish species. The comment on http://www.habitas.org.uk/marinelife/species.asp?item=W14820 regarding low salinity environments certainly fits this observation -- we had record low salinity after spring storms this year.
Feeding: Originally on hydroids in harbor. I'm no hydroid expert, but I'd say they were Obelia of some sort, and Ectopleura were present as well. From reading up a bit, Tenellia adspersa feed on both Obelia dichotoma and Ectopleura crocea. Here's the observation for the Obelia: http://www.inaturalist.org/observations/7813379 And the Ectopleura: http://www.inaturalist.org/observations/7813378
Or the very rare Cuthona virens?

It looks like a Macfarlands, but much lighter without the middle strip. The rhinophores and gills are much darker.

Nudibranch Orienthella trilineata (northern form, about 10mm long) & look-alike amphipod Podocerus cristatus. Scanned from a 35 mm slide I took in the lab in 1984. I had found the specimens in close proximity to each other a few days earlier in the low intertidal at Middle Cove, Cape Arago, Oregon. The amphipod (and her recently hatched juveniles, visible at lower right when viewed large) are on a piece of the outer tube of the polychaete Pista elongata; the slug is on a piece of the hydroid Abietinaria.
Notice the white head tentacles of the slug and the white antennae on the amphipod. Here's what one form of the amphipod looks like in central California, where the southern form of O. trilineata ( with chromium orange on their rhinophores and cephalic tentacles) is prevalent: https://www.inaturalist.org/observations/1103734
Farther south, near Puerto Vallarta, the amphipod lacks white lines, just like the abundant local aeolids!:https://www.flickr.com/photos/8723238@N07/2686177157
