Common name: Halgerda Nudibranchs

Halgerda is a genus of colorful sea slugs, specifically dorid nudibranchs, which are members of the family Discodorididae. These nudibranchs are known for their striking patterns and textures, often featuring a white or yellow body with raised ridges and contrasting spots or lines. They are found in tropical and subtropical seas, usually on or near coral reefs. Halgerda species are not commonly kept in home aquariums due to their specialized dietary needs, as they typically feed on sponges. However, they are admired by divers and underwater photographers for their beauty.
