Ceraesignum
Ceraesignum is a genus of marine snails, specifically sea slugs or nudibranchs, belonging to the family Chromodorididae. The genus is characterized by its striking, often colorful, mantle and its relatively simple anatomy. While many members are visually appealing, the specific taxonomy and distribution of the genus are still under investigation, and new species are being discovered periodically.
Common Names
Due to the recent advancements in research and ongoing taxonomic revisions, common names for Ceraesignum species are scarce. However, some species are known as "Chromodorid nudibranchs" or "Sea slugs" based on their broader classification.
Characteristics
Ceraesignum species are distinguished by their distinctive features:
- Mantle: The dorsal surface, or mantle, is often brightly colored with patterns that are species-specific and can be intricate, ranging from stripes to spots.
- Rhinophores: These are the sensory organs, often club-shaped, that extend from the head and are used to detect food and their surroundings.
- Cerata: These are the finger-like projections on the back of the slug, used for respiration and defense.
- Gill: A prominent gill structure, typically located on the dorsal surface, is used for breathing.
Environments
Ceraesignum species are commonly found in tropical and subtropical waters, primarily in the Indo-Pacific region. They prefer coral reefs and rocky areas, where they feed on sponges and other benthic organisms.
