Glossodoris rufomarginata: The Caramel Nudibranch
Glossodoris rufomarginata, commonly known as the white-margin sea slug or caramel nudibranch, is a stunning marine creature that belongs to the Chromodorididae family. Its captivating appearance has made it a favorite among underwater photographers, scuba divers and critter enthusiasts.

This nudibranch is characterized by its unique color pattern. The central part of its mantle is typically covered in a speckled orange-brown pattern, while the outer edge is adorned with a striking white band. This combination of colors, along with its translucent body, gives it a delicate and ethereal appearance.

Glossodoris rufomarginata is a widespread species found in tropical waters of the Indo-Pacific region. It thrives in diverse marine environments, including coral reefs, rocky shores, and sandy bottoms.

Despite its vibrant colors, this nudibranch is a relatively small creature. Its graceful movements and the way it interacts with its surroundings make it a fascinating subject for underwater photography and observation.
