In this image is Flabellina verrucosa the “Three-lined” aeolid which is seasonally abundant from Baja to Alaska (Behrens, 1991). Aeolids are opisthobranch gastropods known as sea slugs because they have lost their shells. This photo shows the nudibranch’s “oral tentacles” (bottom), ridged sensory antennae called “rhinophores”, “cerata” which contain stolen stinging cells for defense, and a “propodial tentacle”. This aeolid is common year-round at the Race Rocks Ecological Reserve where it is often observed feeding on hydroids such as Tubularia. To the left of it is thesmall Granulina m.

An 8mm long nudibranch

Thanks to Karin Fletcher on iNaturalist for identifying this for us.  She indicated that D. subramosus lack lateral papillae on their rhinophore sheaths and can have brown lines along from their rhinophores along their dorsolateral processes
