The Carminodoris flammea, also known as the Flame Dorid, is a species of colorful sea slug, a type of nudibranch, belonging to the family Discodorididae. This fascinating marine invertebrate is renowned for its vibrant coloration and distinctive features.
Description and Characteristics
The Carminodoris flammea exhibits a striking appearance, showcasing an elongated body with a characteristic orange to reddish-brown hue. It boasts a series of white, yellow, or cream-colored spots and markings scattered across its dorsal surface. These spots are often arranged in rows, creating a visually appealing pattern. The slug’s body is typically quite broad and flattened, adorned with prominent rhinophores and gills. The rhinophores, sensory organs responsible for detecting food and navigating the environment, are club-shaped and readily visible. The gills, located on the posterior end of the body, are branched and serve as the primary respiratory organs. Adult specimens can reach a maximum size of approximately 50 mm.
Habitat and Occurrence
The Carminodoris flammea is a relatively common species found in tropical and subtropical waters. It exhibits a preference for shallow reefs and rocky shores, where it can be observed grazing on its preferred food source. This nudibranch has been documented in various marine zones, including the Indo-Pacific region, the Caribbean Sea, and the Red Sea. Its presence in these diverse ecosystems signifies its adaptability and resilience.
Taxonomy
The species Carminodoris flammea belongs to the Class: Gastropoda, Order: Nudibranchia, and Family: Discodorididae. This classification places it within the larger group of gastropod mollusks, known for their single, spiraled shell. The order Nudibranchia includes a diverse array of sea slugs, characterized by their lack of a shell and their often flamboyant coloration. The family Discodorididae encompasses a group of nudibranchs, which are renowned for their flattened body shape and distinctive feeding habits.
Feeding
The Carminodoris flammea is a food specialist, specifically feeding on sponges. It utilizes its radula, a ribbon-like structure with rows of teeth, to scrape and ingest the sponge tissue. This diet is crucial for the nudibranch’s survival, as it acquires essential nutrients and defensive compounds from the sponge. Some sponges contain toxic chemicals that the Carminodoris flammea can sequester and utilize for its own defense against predators.
