Chromodoris striatella from Hong Kong

From: Bill Rudman & Brian Darvell

Here is some information and photos on Chromodoris striatella from Brian Darvell's Hong Kong collections.

This species is very similar in colour to Chromodoris lineolata and has often been misidentified as that species. Whereas C. lineolata can be described as black with white lines, C. striatella can be described as white with thin black lines, the background colour in C. striatella being a translucent, not pigmented, white. Usually the orange or reddish border has a band of translucent white along its inside edge. The gills and rhinophores are similar in colour to those of C. lineolata. It can grow to 50 mm in length.
