Concerning message #14652:

Dear Bill

I hope you are well and enjoying the weather in Sydney.

I observed something that I belived was a Trapania scurra on September 12th in Futou, Izu Peninsula, Japan.

Locality: Futou beach, 10 m, Izu Peninsula, Japan, Pacific Ocean, 12 September 2009, rock wall. Length: 8-12 mm. Photographer: Ayumi Murakami.

It was in a cavity on a rock wall. The length of this slug was about 12 mm with its body fully extended.

It looked like it was feeding because there was white substance it was crawling around which appeared to be Entoprocts or Kamptozoa that you mentioned on your report from Takako Uno [message #8262].

Any comments you can provide would be greatly appreciated.

Best regards
Ayumi Murakami

Dear Ayumi,

Yes this is T. scurra. As far as I know this is the first record of the species from Japan, so that is a nice find. I have included a close-up of the 'white substance' you thought might be the food of this species. It is indeed a colony of kamptozoa, which certainly suggests they are the food of this species.

Best wishes,
Bill Rudman
