Part of the mollusk phylum, Nudibranchs are the shell-less relatives of the snail and are known for their garish colors. These tiny sea creatures are usually only 2cm - 6cm in length and can be found worldwide. They are able to thrive in any depth of salt water from the deepest darkest ocean floors to warm shallow water.

There are over 3,000 known species of nudibranchs, and scientist estimate that only half have been discovered so far. The creatures soft-body and short life span of 1 year make it possible for many of them to live undetected and vanish from the earth without a trace.

Nudibranchs are blind, and the animal relies on smell, taste and feel to navigate their surroundings to find coral, sponges, eggs, small fish, and other nudibranchs to eat.
The nudibranchs most exceptional aspect is their incredible color palettes. Some species' palettes match the dark greens and browns of their ocean surroundings, while others boldly contrast the colors of their habitats. These brilliant colors are an evolutionary development that began when they first shed their shells for other defense mechanisms; either to blend in to their surroundings with camouflage or as warning sign for any animals thinking of dining on a tasty little nudibranch, letting them know of their toxic secretions and stinging cells. As it is, some species dine on toxic sponges which alters and stores the sponges toxic compound in the their bodies and are able to secret them from glands when bothered.

Nudibranchs have been studied extensively by scientist looking at their simple nervous systems for clues to learning and memory and their chemical makeup in search of pharmaceuticals.

I was similarly inspired myself recently--this pallette inspired by a 19th century book plate of sea cucumbers, close (more sessile) cousins to the nudibranchs.

I first learnt of these about 40 years ago and then it was only a notation about an individual 'animal' in a section about sea cucumbers. It was supposed that this one creature could change colours at will, not unlike an octopus.
