Trinchesia genovae is a species of sea slug, a nudibranch, a marine gastropod mollusk in the family Trinchesiidae.
Description & Characteristics
Trinchesia genovae is a small nudibranch, with a maximum size of around 10 mm. It has a slender, elongated body with a distinctive orange-red coloration. The body is covered in small, white spots, giving it a speckled appearance. The rhinophores, or sensory organs, are long and slender, and the cerata, or finger-like projections along the back, are numerous and well-developed. Trinchesia genovae also has a distinctive oral veil with a pair of small, black eyes.
Habitat and Occurrence
Trinchesia genovae is a common species found in the Mediterranean Sea. It typically inhabits shallow coastal waters, particularly in areas with rocky substrates and abundant algae. Its distribution encompasses various marine zones, including the infralittoral zone, the intertidal zone, and even the circalittoral zone. This makes it a prevalent presence in these aquatic ecosystems.
Taxonomy
Trinchesia genovae belongs to the Class: Gastropoda, Order: Nudibranchia, and Family: Trinchesiidae. This family is characterized by its members’ slender bodies, cerata, and distinctive rhinophores. Within this family, Trinchesia genovae is further classified as a member of the genus Trinchesia, a group of nudibranchs known for their orange-red coloration and speckled appearance.
Feeding
Trinchesia genovae is a carnivorous nudibranch that primarily feeds on hydroids, small colonial animals related to jellyfish. It uses its radula, a ribbon-like structure in its mouth, to scrape and ingest the hydroid polyps. This feeding behavior is crucial to the species’ survival as it provides it with the nutrients and energy it needs to thrive.
