Notodoris gardineri - juvenile

January 3, 2003
From: Bruce Potter


Dear Bill,
There was a discussion a few weeks ago about the possibility that juvenile Notodoris might have dark rhinophores, which became pure yellow as they got older.

Yesterday I found this adult Notodoris gardineri not far from two other adults, and then noticed the tiny juvenile centre foreground. The juvenile was about 14mm. long, while the adult was about 90mm.

I noticed that the juvenile has black tipped rhinophores. I went back and had another look today, and the juvenile is still with the adult. Not far away another adult was laying eggs. This was at about 16 meters near a boat wreck on coral and rubble, just outside of Honiara, Solomon Islands, 22 December 2002.
Regards

Thanks Bruce,
It certainly looks as though the three yellow species have black-rhinophored juveniles. Unfortunately close proximity of adults and juveniles does not mean they are a family group, it just means they all like feeding on the same sponge. What we need now is a few more intermediate stages showing the rhinophores, or best of all a captive animal which could be seen changing colour
Best wishes,
