The underwater world feels like stepping into a living aquarium where the glass has quietly vanished. Colorful coral reefs glow like underwater cities, while bizarre rock formations twist and pose as if competing for attention. Curious fish drift by for magical meet-and-greets, clearly unimpressed by human visitors in bubbles. Then suddenly a shark, manta, or other majestic predator glides past, turning the scene into a blockbuster moment. It is breathtaking, slightly absurd, and proof that Neptune definitely has a sense for beauty.
