Green Island (04-07Apr13) 097_2.jpg
Dragon Gate Rock Reef (Long Men Yan Jiao), Green Island -- An as yet undescribed Arminid nudibranch of the Janolus species on a leather coral.<br />
<br />
This species was previously only known from Indonesia, but I guess Taiwan can now be included in its range of distribution!<br />
We observed this individual on a leather coral at a depth of 17-18 m. An unusual orange branched sensory structure, known as a caruncle, is clearly visible between the nudibranch's rhinophores.
