Chromodoris dianae -flattened egg ribbon

December 6, 2002
From: Mary Jane Adams

Hi Bill,
I found this Chromodoris dianae laying eggs in Lembeh Strait, Sulawesi, Indonesia. I am surprised to see that the egg ribbon is laying flat, not standing on edge as with most Chromodorids. I wonder if this is typical of this species or due to the rough substrate this slug has chosen to lay it's eggs.

Divesite: Nudi Retreat,
Depth: 10-15 meters,
Date: November 19, 2002.

Best regards,
Mary Jane

Dear Mary Jane,
Thanks for this very interesting observation. As Scott Johnson noted in an earlier message, the species of Chromodoris with longitudinal black lines, that we know about, lay these flattened egg ribbons. I think your photo is the first record of this species' egg ribbon so its a nice addition to the story.
Best wishes,
Bill Rudman
