Monterey Nudibranch

About 30' down on the riprap. Looks like Laila cockerelli color morph, but...

Looks like: https://www.inaturalist.org/taxa/47766-Limacia

Found using the Nudibranch ID feature here: https://skaphandrus.com/en/ocean-life-identification/Nudibranchs

and googling the names of the short listed nudis. A little klunky sometimes but probably about 50% successful in finding an ID.

This shows the features selected on the species page: https://skaphandrus.com/en/marine-animals/species/Limacia-janssi

Ah! Limacia cockerelli seems to be Laila cockerelli. I have just got to keep up with the trends.

Thanks for the site information; I'l be using it.

The other useful resource is the Nudibase facebook group:
