Thanks Rich,

Good eyes. Now that folks are looking closer at sea slugs, this kind of association is becoming more common. The only problem is we don't understand what the association is. Is the worm feeding on the slug, or just walking over it.

Note to others, Rick is assisting, Bill Pence and Doug Mason, two high school science instructors in California, in a genetic study to determine whether the three color forms of this dorid, are distinct species themselves. External morphological differences suggest they might be, but internal anatomy is largely identical.

Thanks for sharing,
Dave Behrens
