Northwest Dive Club

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.

Thanks!

I saw a few at the Pinnacle & Pullali West Wall (hood canal) about 2-3 weeks ago. Also have seen them at Keystone last month.
Headed up to skyline right now, will let you know if I spot any.

Dan, these are all over Fox Island Bridge and Day Island Wall. Those are two places I see them a lot. However, the best is Salt Creek IMO.

I second the Fox Island Bridge pilings. I've seen them every dive there the last two years.

Great! Thanks for the help everyone.
