Tambja sagamiana from Taiwan

July 24, 2003
From: Todd Garthwaite

Hi Bill,
I was surprised to see that The Forum only has two records of Tambja sagamiana. Here are several shots of T. sagamiana, (which I spotted in a shallower area of the same dive site where I discovered 3 specimens of Tambja kushimotoensis, that I am sending in a separate message. This is my first time to see any Tambja species in north-eastern Taiwan.) I must say T. sagamiana is a spectacular animal, and probably the most colorful and exotic nudibranch I have seen off Taiwan’s N.E. Coast thus far!

Site: "The 2nd Wall", FanZai Ao ([Barbarian Cove] N.E. Coast, Taipei County, Taiwan),
13 July 2003, 10:48am
Depth: 12.1 meters. Water temp.: 27 deg. Celsius. Size: approximately 70+ mm.
Stay golden.
Peace, love, & nudis

Dear Todd,
Thanks for these photos. I have included a close-up of the side of the head to show the peculiar sensory organ which we find in species of Tambja. Usually all we see is a dark line, or groove along the side of the head, but when it opens out, this 'pit' is a series of ridges which are presumably chemosensory in function, used for 'smelling'. This organ is also well illustrated in your photos of T. morosa [=T. kushimotoensis'.
Best wishes,
Bill Rudman
