Wind Dancer Nudibranchs are some of the most beautiful.

It is important to note that it is EXTREMELY difficult to find and photograph Nudibranchs. With the photos you find on the Internet, you would get the impression that they are readily available. In fact, they are extremely rare and are usually very deep down which requires extensive SCUBA knowledge and equipment.
Photographers of nudibranchs are thus very protective of their photos so I want to make sure I give due credit here.
