Scientific Name: Oxynoe viridis
Common Name: Green oxynoe

Adult Size: 5 – 15 mm
Depth Range: 1 – 10 m
Biotope / Habitat: Shallow seagrass beds and algae-covered rocks, often hidden among green algae
Diet: Specialized feeder on green algae (Caulerpa spp.), using its radula to gently suck out the algal cell contents
Reproduction: Hermaphroditic; mates reciprocally, with tiny, coiled egg ribbons laid on algae and seagrass blades
Fun Fact: Oxynoe viridis uses kleptoplasty, stealing chloroplasts from the algae it eats and storing them in its tissues — effectively turning itself into a “solar-powered” slug!

This charming green slug is perfectly adapted to blend with its algal habitat, making it a delightful find for macro photographers and algae-loving divers.
