Definition
-
Facelina annulicornis is a species of sea slug belonging to the family Facelinidae, commonly known as the annulate facelina. These marine gastropods are found primarily in the Mediterranean Sea and the northeastern Atlantic Ocean, as well as in adjacent waters.
The Facelina annulicornis typically reaches a size of about 2 to 4 centimeters in length. It displays a remarkable coloration, featuring a translucent body with various shades of green, yellow, and brown. This species has prominent cerata, which are finger-like appendages arranged in rows on its back. The cerata are often marked with contrasting colored bands, giving it a distinctive appearance.
Like many other nudibranchs, Facelina annulicornis is a carnivorous creature that feeds on small invertebrates and hydroids. It utilizes its specialized radula, a small toothed structure, to scrape off its prey from various surfaces.
Due to its vibrant colors and intricate patterns, Facelina annulicornis is highly sought after by underwater photographers and divers. When disturbed or threatened, this sea slug can retract its cerata and cautiously move away using muscular contractions. The slug's venomous nature is also under investigation, as it could potentially serve as a self-defense mechanism.
In conclusion, Facelina annulicornis is a visually stunning sea slug species that inhabits the Mediterranean Sea and northeastern Atlantic Ocean. Its translucent body, adorned with unique color patterns and bands, make it a captivating sight in marine environments.
Etymology of FACELINA ANNULICORNIS
The word "facelina annulicornis" is a scientific binomial name used to classify a species in the animal kingdom. Binomial names are composed of two parts: the genus name (in this case, Facelina) and the specific epithet (annulicornis).
The genus name "Facelina" refers to a group of sea slugs belonging to the family Facelinidae. The specific epithet "annulicornis" comes from Latin roots. "Annulus" means "ring" or "circular band", and "cornis" means "related to the horn". Therefore, "annulicornis" can be interpreted as "having ringed or banded horns" or "related to a circular band-like structure".
In scientific naming, the binomial system was introduced by Swedish botanist Carl Linnaeus to provide a universal method for classifying and naming species.
