What is a leaf sheep?

The "leaf sheep" isn't actually a sheep at all! It's a common name for a species of sea slug, specifically Costasiella kuroshimae. Here's some information about them:

• Appearance: They are incredibly small, typically reaching only a few millimeters in length. Their bright green color, combined with their leaf-like shape, gives them their charming name. They have small, cerata (finger-like projections) along their back that give them their somewhat fluffy appearance.

• Diet: These sea slugs are herbivores and are known for their unique ability to photosynthesize. They eat algae, and through a process called kleptoplasty, they absorb chloroplasts from the algae and incorporate them into their own tissues. This allows them to generate energy from sunlight, supplementing their diet. This is a rare trait among animals.

• Habitat: They are found in the waters surrounding Japan, the Philippines, and Indonesia. They live in shallow, tropical waters and prefer areas with plenty of algae.

• Behavior: They are relatively slow-moving creatures. Their small size and camouflage make them relatively well-protected from predators.

• Reproduction: Like other sea slugs, they reproduce sexually, laying eggs in clusters.

In short, the leaf sheep is a tiny, charming, and remarkably unique creature of the sea, famous for its vibrant green color, leaf-like shape, and its ability to photosynthesize.
