DSC_7066 White nudibranch (Atagema carinata) usually circular - even when crawling, and with a high narrow longitudinal mid dorsal ridge. Difficult to distinguish on reefs because of its resemblance to white encrusting sponges or ascidians. Found in sheltered localities such as harbour channels. Pudding Island, Otago Harbour *
