A nudibranch is a soft-bodied, marine gastropod mollusk which sheds its shell after the larva stage. Most nudibranchs have extraordinary colors and striking forms. Nudibranchs are often called “sea slugs”.
Below you will see a photo of what I am fairly sure is a Glossodoris Sedna nubibranch that I took while diving in the Bahamas near the Exumas. These spectacular creatures are often very small and almost always hard to find.
