Dear Koh,
Yes I would agree that this is T. sagamiana. We now have records from Taiwan and South Korea, as well as Japan.
Best wishes,

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

Hi Bill,
Concerning variation of Tambja sagamiana as suggested in a recent post to the Forum, here are two images of Okinawa animals. The color here seems to be relatively constant without much variation (orange or yellow spots).

Upper: Horseshoe Cliffs, Okinawa; 19 Jan '91; photo only, size not recorded; from 49m.
Lower: Seragaki, Okinawa; 22 Dec '96; TL: 80mm; from 43m.
Cheers,
Bob

Dear Bill,
Thanks for your help. Here is a photo of Tambja sagamiana for reference on your Forum. This species is one of the common slugs at Kushimoto, Japan, in winter and spring. On the otherhand Tambja cf. verconis is very rare.
Best Regards,
