The cover image features a striking blue-and-yellow variation of Costasiella kuroshimae, photographed during a dive in Tulamben, Bali. These tiny sacoglossan sea slugs are among my favourite underwater creatures, and it is easy to see why. Their vibrant colours, distinctive shape, and almost cartoon-like appearance give them a remarkable charm. With their expressive cerata and sheep-like faces, they seem more like characters from an animated film than real marine animals. Every encounter with one brings a smile to my face. Despite the incredible diversity of life beneath the surface, there is something uniquely endearing about these tiny creatures that makes them unforgettable and ensures they always stand out among the ocean’s many wonders.
