Anyone have an ID on this one? it was about one inch long. Closest I can find is a Bus Stop Nudibranch.

海鞘綱 (綱 Ascidiacea)觀察者
alex_shure描述
I'm calling in ID help from anyone who knows what this might be. I found it on this Botrylloides colony, and though not represented in the pics, it was 'vibrating' in quick intervals, difficult to observe with the naked eye, though you could easily see it's motion. For lack of better description, it looks like an orange tadpole.
Oddly enough I encountered another one in a photo I took, though I did not notice that individual in person. See that observation here (left-center):

Any thoughts?

I'm assuming this is juvenile Cancer based on the ridges on the carapace. Interesting lack of pigment

Higher quality pics to be uploaded. Seems similar to C. trophina or maybe verrucosa but I’m not very familiar with either species. @anudibranchmom @luanroberts any tips on ID?

Both C. perca slugs I found yesterday at Lake Merritt seemed to have some sort of evenly-spaced, stalked growths on all their surfaces, perhaps some sort of parasite, fungus, virus or ? The overall impression was "furry." The other one, which I brought over to the microscope (https://www.inaturalist.org/observations/240871810), also shows these growths and was photographed by @audreyfalconer1, @pacificplankton, @leslieh, @ktnoonan, @chilipossum and possibly others as well.

Update: those might be ciliates in genus Scyphida, according to Jeff Goddard (see comments below).

This nudi was about 5mm long. It looks like a juvenile of a Rabbit Dorid, Cockerell’s Dorid, or a Clown Dorid without the orange tubercles typically seen on adults. Maybe it’s not one of them. Any help is appreciated. Thx

Doto sp. with eggs was located on artificial reef at a depth of 30 feet. Lengths were 0.2 cm. Water temperature was 54 degrees F.
I am not sure if this is Goddard's Doto form A or Doto amyra.

@jeffgoddard I went through my photos and think I found the species you mentioned. This species appeared to be pretty widespread at this site. I had assumed it was some type of tunicate.

Awesome!!! Was found moving by surface tension (like in third pic) near eelgrass. Was then moved to a black box temporarily for photos then returned.
