I have a friend from California who is a slug researcher doing genetic testing on Flabellina trilineata. She'll be coming up to the Seattle area later this month to try and collect a few. Has anyone seen this slug at dive sites around Puget Sound? I've found them in large numbers recently at Titlow but I'm wondering if they might located elsewhere as well. (Titlow is a protected marine sanctuary so scientific collection is prohibited.)
As you can see in the photo below Puget Sound versions of this slug lack the orange tipped Rhinophores that are typical of other locations.
