Babakina caprinsulensis is a rare nudibranch that has only been documented in New Zealand. I thank mollusc-expert Dr Richard Willan for his identification of this species. He says that a distinctive feature of this nudibranch is the way that the rhinophores sit next to each other on top of the head, as though they were connected together.
During the day Janolus ignis hides within clumps of the bryozoan Orthoscuticella aff. margaritacea. Emerging at night, it is one of the fastest moving nudibranchs I have encountered.
Introducing Dendrodoris krusensternii
In August the distinctive creamy brown nudibranch with bulbous nodules and fluorescent blue spots, known in New Zealand by the common name Gem Nudibranch, underwent a name change from Dendrodoris denisoni to Dendrodoris krusensternii.
