Concerning message #17018:

Dear Bill ,

First I noticed the egg mass and then began searching for the "beauty".  I found it one meter from the eggs .

The worm came from nowhere and start harassing (on top) then stopped and started again but the "beauty" put an end to the story. After climbing on the worm's head they separated .

Regards,
Joseph

Dear Yossi,
It's certainly a possibility that the chromodorid produced the egg ribbon, but it could just be a coincidence. It will certainly be worth looking out for more occasions when this species is found near this type of egg ribbon. Your worm observation is quite interesting. I thought I had noticed a bit of damage on the back of the nudibranch in your earlier photos and it certainly looks as though the worm actually had a bite or two  before giving up for some reason. I can't recall other observations of polychaetes eating or biting nudibranchs so this is a valuable record.
Best wishes,
Bill Rudman
