Thecacera sp?

July 31, 2002
From: Jim Anderson

Dear Dr. Rudman,
The attached shows an animal seen recently in Sulawesi, Indonesia. It was on a sand bottom among small coral outcrops and was spotted by our guide Erwin right under our fins at the start of the dive as we hit the bottom. It appears similar to Debelius' Thecacera sp. (page 190 in my edition).

Details
Size: approx 15mm
Location: Molas reef, NE Sulawesi.
Date: 3 July, 2002, approx 2.45pm
Depth: 16metres
Water Temp: 29 deg C

Please advise.
Kind regards,
Jim A

Thanks Jim,
It certainly looks like a species of Thecacera and its orange and black colour pattern has similarities to that of Thecacera pacifica. That species, amongst other things, does not have black spots on the body and does have a black line along the outside edge each gill. Until we get some more information on its colour variation I guess we should just call it Thecacera sp. 2 as it unlike any of the few other known species in colour pattern.
Best wishes,
Bill Rudman
