Pectenodoris trilineata from Indonesia

January 3, 2007
From: Erwin Kodiat

Hi Bill,
This one was taken in North Sulawesi. It is so tiny that last year when I saw it in Bali, I thought it was a juvenile, but the in one occasion in Seraya, Bali, I saw this kind of nudi this size laying eggs, so I guess it is already in adult form. But since my pocket camera can not take the picture of this, I can't send you any photos. But luckily, when I went to North Sulawesi, I got a borrowed 100 mm macro lens, I can take this picture. Can you help me ID this?

Locality: Tanjung Popoh, North Sulawesi, Indonesia, Gulf of Manado, 30 October 2006. Length: 1.5 cm. Photographer: Erwin Kodiat.

Dear Erwin,

This is indeed a small species of chromodorid, seldom growing more than about 10 mm in length. It is Pectenodoris trilineata.

Best wishes,
Bill Rudman
