Tritoniid sp. 8 from Indonesia

Dear Bill,
I photographed the attached image at Lembeh Strait too. It seems not to be rare there.
I found it in the shallow place with a depth of 7m. I suspect that the red soft coral this animal hangs on is their food?

Thanks to the transparent body surface of this animal, the heart or internal organs was observable. I could also see the genital orifice and anus. I ould also see some cream-colored tubercles in the skin but I can not imagine what they are.

Date: 21 Nov,2001
Loc: Lembeh Strait, Sulawesi, Indonesia.
Depth: 7m
Length: 50mm

I have a question about the name 'Tritoniid sp. 8' you have given to this animal on the Forum. I would have called it Tritonnidae sp. I have tried to search the meaning of the "Tritoniid", but I could not find it. Would you explain the difference when you say "Tritoniidae" and "Tritoniid".

Best Regards,

This species has now been named Tritonia bollandi. - Note added 16 Aug 2003

Thanks Nishina,
I have labelled the main openings in the closeup alongside. The small pore alongside the anus is the kidney opening. I am not sure what the creamy spots - usually grouped in 4 - that can be seen through the skin. It is possible they are some parasite.

Concerning the meaning of 'Tritoniid'. It is just a descriptive word for members of the family Tritoniidae, just as I use 'chromodorid' to describe members of the Chromodorididae.
Best wishes,
Bill Rudman
