Hope you've had a good holiday season.
We had two questions regarding Glossodoris symmetricus:
1. Why symmetricus and not symmetrica?
2. In your study of the animal, did you find that the red color is something like fluorescent? We encountered it at 32 m and both of us said after the dive that we could see the red color in the deep without artificial light, unlike other chromodorids with red or orange color where the color looks gray to brown in available light.

Thanks for the New Year's greetings. It was 45º C here on January 1 - I hope that was an aberration and not a sign of things to come!
Thanks for the nice photos of G. symmetricus. You ask a couple of interesting questions. Concerning symmetricus versus symmetrica. I am not a Latin scholar and used to check my names with a colleague who was. However you may be right. I will check it out.
Concerning the colour. I have never seen this species alive - only from specimens and colour photos. If you did see red it would suggest the animal- or something in it - is perhaps producing red light - a very unusual phenomenon, which would be worth following up if you get the opportunity.
