Description
editThis goniodorid nudibranch is translucent white in colour with brown spots and patches. The pre-rhinophoral papillae and gills are tipped with yellow and there is a line of white pigment with diffuse edges along the ridge of the tail. The front of the rhinophores is brown and the tips are white. There are two long extra-branchial papillae which are translucent white with some yellow and brown streaks on their upper surfaces.[2]
Ecology
editAncula kariyana probably feeds on Entoprocta which often grow on hydroids, bryozoa and other living substrata.
