What Is a Leaf Sheep (Costasiella)?
The leaf sheep, scientifically known as Costasiella kuroshimae, is a tiny marine sea slug belonging to the sacoglossan group of gastropods. At first glance, it looks almost unreal-like a cartoon creature or a living plant with eyes. Its leaf-shaped appendages, soft pastel-green coloration, and sheep-like face have earned it global fame as one of the cutest marine animals ever discovered.

Its leaf-shaped appendages, soft pastel-green coloration, and sheep-like face have earned it global fame as one of the cutest marine animals ever discovered.
Despite its adorable appearance, the leaf sheep is not a toy, novelty pet, or decorative aquarium animal. It is a highly specialized marine invertebrate with unique biological requirements and survival strategies that differ greatly from fish or common aquarium invertebrates. Understanding what a leaf sheep truly is-beyond internet images-is essential before considering keeping one in captivity.
Leaf sheep are exceptionally small, usually measuring 5-10 millimeters in length. Their tiny size makes them fragile and highly sensitive to environmental changes. They possess no shell for protection, relying instead on camouflage, chemical defenses, and an extraordinary adaptation that sets them apart from nearly all other animals: photosynthesis.
Yes-leaf sheep can harness energy from sunlight.
Through a process called kleptoplasty, leaf sheep consume specific algae and retain the algae's chloroplasts within their own tissues. These chloroplasts continue to photosynthesize inside the leaf sheep's body, providing supplemental energy. This ability blurs the line between plant and animal and has fascinated scientists for decades.
