In Papua New Guinea's waters, an Aeolid nudibranch gracefully perches on an orange sponge. Its delicate body adorned with striking hues creates a breathtaking sight that showcases nature's artistic prowess. Venturing into the depths of Bali's Seraya during a blackwater night dive reveals another enchanting spectacle - sea butterflies floating effortlessly in the water column. These ethereal beings resemble miniature angels with translucent wings fluttering gently amidst the darkness. Their presence adds an otherworldly charm to this underwater realm.
