The 'Not So' Gloomy Nudibranch (Tambja morosa)

  They call this the 'gloomy nudibranch'! Doesn't look so gloomy to me. This hard to find sea slug has the deepest royal blue I have ever seen in an animal. The blue markings are different from slug to slug but the blue vizor over the 'eyes' is a pretty common feature. If you catch it in the right light the dark black features meld into a green tint especially towards the exposed gills.

  You will have to be pretty lucky to find this nudibranch in Hawaii, but you can see different color variations elsewhere in the Indo-Pacific.
