I went there expecting to see nothing, because it felt like looking for a needle in a haystack. In the end, I was especially grateful to the captain for his perseverance. I saw hundreds of dolphins returning. The crew kept looking for whales in the vast ocean. Everyone thought there was no hope today, but they found a group of whales and the ethereal sound of whales that can only be seen in documentaries. It was a pity that I didn't take a photo. It was an amazing day! It was worth it!
