Leaf Sheep Sea Slugs Grazing on Algae in Bali

A group of tiny leaf sheep sea slugs (Costasiella kuroshimae) graze on green Avrainvillea algae blades in Bali. Their translucent, pale green bodies feature leaf-like cerata tipped with pink and black spots, alongside dark eye-spots and simple rhinophores. Directed macro lighting captures the minute details of these photosynthetic sacoglossan sea slugs resting on their host plant. Soft ambient focus blurs the surrounding seabed substrate while highlighting species interaction on the algae leaf. Ideal for marine biology journals, educational publications, and professional ocean stock media.
