Adult Size: 10 – 25 mm
Depth Range: 5 – 20 m
Biotope / Habitat: Shallow coral reef slopes and rocky outcrops, often seen gliding over algae-covered surfaces and rubble
Diet: Feeds on green algae, using its radula to gently scrape and consume cell contents while retaining chloroplasts (kleptoplasty)
Reproduction: Hermaphroditic; mates reciprocally, with small, coiled egg ribbons laid on algae or in protected reef areas
Fun Fact: Thuridilla virgata’s elegant light blue body is adorned with black stripes and orange-tipped rhinophores, creating a dynamic, streamlined look that stands out among the algae!

This striking “solar-powered” sea slug is a delight for macro photographers and algae-loving reef explorers, adding a gentle splash of color to the reef’s green canvas.
