You step off the stern into warm, ink-black water; lights from the boat stitch a soft halo, and the ocean answers with a slow, patient pull. Minutes later a shadow the size of a truck unrolls beneath you—an adult manta glides in, wings sweeping plank-like arcs as plankton lanterns cling to its mouth. The animals don’t flit away; they inspect, feed, and perform slow-motion turns as currents nudge them into the light.
