Description

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.

Water quality data:
Temp: 23.6 degrees C
SAL-ppt: 33.93
pH: 7.89
DO: 86.6 (top)

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