Mauritius’ Most Iconic Nudibranchs

Mauritius is more than just turquoise lagoons and white-sand beaches — it's also home to an incredible diversity of nudibranchs, the flamboyant sea slugs that fascinate underwater photographers and marine life lovers alike.
In this article, we explore the most emblematic nudibranch species found around Mauritius — some easy to spot, others more secretive, and a few exclusive ones that have only recently made their debut on our reefs.

Thuridilla virgata is a slender and graceful sea slug, easily recognized by its greenish body adorned with thin, white to bluish longitudinal stripes. Like other sacoglossans, it feeds on algae and is often seen gliding over seagrass beds or rocky reef flats in shallow waters. Its calm movements and sleek, ribbon-like shape give it a refined elegance, making it a rewarding find for divers and photographers who take the time to look closely.
