When I first saw the school of manta rays, I was overwhelmed by both fear and astonishment. It didn't take long for my emotions to settle. After calming down, the sight of the manta ray school before my eyes was magnificent. It resembled a heap of fallen leaves, reaching deep into the ocean depths, but there was a distinct difference from that. Order and chaos. The movement of the manta rays was remarkably orderly, as they glided in unison in one direction. It seemed as if each individual was connected like a network.
