Unnamed spotting


Nudibranch larva about 1mm in size, can see a blue dot with the naked eye but of course it is better seen under a microscope. Fleshy flipper like appendages that are iridescent blue. Clear-ish silvery iridescent body that flattens out into appendages. Purple lower body and tail.


Came from a plankton tow from 120 meters deep so it could be from anywhere from 120 till surface at station ALOHA- A Long-Term Oligotrophic Habitat Assessment; 22° 45'N, 158° 00'W, on a STARS cruise aboard the Kilo Moana


The most beautiful thing I have ever seen! I think it is a Glaucus atlanticus

Hi aliat, I think this is a Glaucilla marginata (closely related to Glaucus atlanticus). Here is my spotting of Glaucilla marginata - check out the linked references. And this is a Glaucus atlanticus:

Lovely spot! You might like to add it the the Nudibranches of the World & Mollusca missions.

Fabulous creatures. They eat jellyfish and incorporate the 'stings' to protect themselves. Great trick.
