Flabellina pedata, a stunning sea slug species, belongs to the family Flabellinidae within the superfamily Flabellinoidea. This marine gastropod mollusc, part of the class Gastropoda and phylum Mollusca, is known for its vibrant coloration and fascinating behavior. Flabellina pedata is commonly found in the Mediterranean Sea, making Gozo an excellent location for divers to observe these captivating creatures.
Identifying Flabellina pedata is straightforward due to its distinctive appearance. This nudibranch is recognized by its overall pink-purple coloration. The body and cerata (finger-like appendages) are adorned with this vibrant hue. The extremities are tipped with opaque white pigment, creating white rings at the tips of the cerata. The digestive gland, often visible through the cerata, is usually red but partially masked by the purple coloration. Flabellina pedata can grow to about 20 mm in the Mediterranean, while those in the Atlantic Ocean can reach up to 50 mm.
Flabellina pedata exhibits several notable characteristics:
Flabellina pedata is usually found in sublittoral zones, thriving on hard substrates such as rocky surfaces that are somewhat exposed. These nudibranchs are often solitary or found in pairs. They prefer areas where they can feed on their primary diet, the hydrozoan species Eudendrium. The spawn of Flabellina pedata appears as a thin white thread, typically wound around the Eudendrium on which they feed.
An interesting fact about Flabellina pedata is its feeding and reproductive behavior. These nudibranchs feed on Eudendrium, a sparsely-branched hydrozoan. When it comes to spawning, Flabellina pedata lays a thin white thread of eggs, usually wrapped around the Eudendrium. This behavior ensures that their offspring have an immediate food source upon hatching, increasing their chances of survival.
Gozo dive trips offers excellent diving opportunities to observe Flabellina pedata in its natural habitat. Notable diving spots include:
