Noalda sp. 2
Known only from Andaman Sea
Locality: Tablamu, 6 metres, Phangnga, Thailand, Andaman Sea, east Indian Ocean, 13 February 2010, Rocky shoreline. Length: About 3 mm. Photographer: Lawrence Neal.
The yellow markings and general shape are very similar to that of Noalda exigua [see message #23262]. However the head of this animal looks more like that of a gastropterid and the shell is more enclosed than in N. exigua. However until we know something of the anatomy of these animals I couldn't positively say the resemblance is more than co-incidental. It would not be the first time that we have been tricked by external similarities in unrelated primitive opisthobranchs.
To keep it simple I will include this animal as a species of Noalda. It is is the second species I have tentatively included in this problematic genus [see Noalda sp. 1]Authorship details
