Aldisa? from Hachijo Island Japan

July 7, 2002
From: Shouichi Kato

Dear Bill,
This pretty animal was found by my staff Hidenori Ando, on the rocky wall 15m in depth. He felt it, if anything, a little bit hard. We couldn't reach his name.
Please advise.

Best regards,
S. Kato

Dear Shouichi,
This looks ike it could be the same as Scott Johnson's Aldisa sp. 5 from Hawaii. Although not that clear in his photos he describes the colour as having 'patches that are more yellow, bordered by almost iridescent patches of bluish purple' which fit your animal well. One distinguishing feature of Scott's animal is that it is covered in low rounded bumps. If you have another photo, perhaps from the side of the slug, we might be able to see if it has the same bumps. It might also show if there are the characteristic pits in the dorsal midline.
Best wishes,
Bill Rudman
