The Sea Sheep (Costasiella kuroshimae) is a tiny, adorable sea slug from the Indo-Pacific that resembles a cartoon sheep. It performs indirect photosynthesis through kleptoplasty ("stolen plastids"), by eating algae and incorporating the chloroplasts into its body. Stored in its back protrusions (cerata), these give the slug its color and allow it to generate energy from sunlight. Its "ears" are sensory rhinophores.
