Thuridilla sp. 6 (undescribed)

I can't tell you how excited we were when William Tan sent us this photo. No question - it had to go on the cover of Nudibranchs & Sea Slug Identification. We don't know much about this sapsucking slug, but we do know it is one knock out on the color chart. The blue body with undulating orange to brown pattern along the parapodial margin, punctuated with yellow spots is a total give away.

Willam shot this one in Malaysia. His specimen was about 20 mm in length. One thing for sure, we will be looking for it in Anilao at this March's Nudibranch Workshops in Anilao.
