Scientific Name: Thuridilla indopacifica
Common Name: Indo-Pacific thuridilla

Adult Size: 10 – 25 mm
Depth Range: 5 – 20 m
Biotope / Habitat: Coral reef slopes and rocky outcrops, often seen gliding over algae-covered rocks and rubble patches
Diet: Feeds on green algae, using its radula to gently scrape out cell contents for nourishment and chloroplast retention (kleptoplasty)
Reproduction: Hermaphroditic; mates reciprocally, with small, coiled egg ribbons laid on algae or reef rubble
Fun Fact: Thuridilla indopacifica is easily recognized by its narrow, leaf-like body in vibrant green hues with thin blue and white lines, blending perfectly among algae while capturing sunlight’s power!

This colorful little slug is a master of camouflage and a favorite subject for macro photographers and algae-loving divers alike.
