The Sphon’s Chromidorid – Felimida sphoni is a species of sea slug, a colorful nudibranch belonging to the family Chromodorididae. These striking creatures are known for their vibrant coloration and intricate patterns, making them popular subjects for marine photographers and enthusiasts.
Description & Characteristics
Felimida sphoni is a relatively small nudibranch, reaching a maximum size of about 30mm in length. The body is typically elongated and oval-shaped, with a distinct head and a pair of rhinophores (sensory organs) located on the top of the head. The mantle, or outer covering of the body, is smooth and glossy, adorned with bright colors that vary depending on the individual specimen. The coloration is often a combination of vivid yellows, oranges, reds, and browns, with intricate patterns of spots, lines, and blotches. The specific coloration and pattern of the Felimida sphoni can vary geographically, leading to several distinct color forms within the species.
Habitat and Occurrence
The Felimida sphoni is typically found in shallow, tropical waters, inhabiting the intertidal zone and the subtidal region to depths of around 10 meters. It is primarily found in the Indo-Pacific region, with a distribution that extends from the Red Sea and East Africa to the Pacific Ocean, including Indonesia, the Philippines, and Australia. The Felimida sphoni prefers areas with abundant coral reefs, as these environments provide both shelter and a rich source of food.
Taxonomy
The species Felimida sphoni belongs to the Class: Gastropoda, Order: Nudibranchia, and Family: Chromodorididae. This family is characterized by its brightly colored members, many of which display a striking combination of vibrant hues and intricate patterns. The Chromodorididae is a large and diverse family, with over 300 species known to date. The family is further divided into numerous genera, including Felimida, which contains several other species of nudibranchs.
Feeding
Felimida sphoni is a food specialist, feeding exclusively on sponges. This dietary preference is reflected in the species’ coloration, which often mimics the color and patterns of the sponges it consumes. The nudibranch uses its radula, a ribbon-like structure in its mouth, to scrape the sponge tissue and ingest it. While sponges are a major food source, the Felimida sphoni may also occasionally consume other invertebrates, such as algae and hydroids, in its environment.
