Sinuous Phyllidia

Phyllidiella meandrina

Phyllidiella meandrina is a distinctive nudibranch characterized by its black body adorned with longitudinal pink ridges along the mantle's sides and oval rings in the center of its back. The rhinophores, which are sensory organs, are also black, aiding in its identification. This species was initially collected in Mauritius and is often found in the waters around Mauritius and Réunion, making it a common sight in these regions. Typically, the Sinuous Phyllidia inhabits areas rich in sponges, which form the primary component of its diet. As a herbivorous creature, it feeds on these sponges, contributing to the ecological balance within its habitat. While specific breeding behaviors are not detailed in the sources, nudibranchs are generally known for their hermaphroditic reproduction, laying eggs in gelatinous ribbons. Encountering Phyllidiella meandrina during a dive can be a unique experience, as divers observe its slow-moving nature and distinctive coloration against the backdrop of the reef. The conservation status of this species is not evaluated, indicating a lack of specific information regarding its population trends.
