Occurred on May 10, 2023 Santander, Cantabria, Spainbr br : "On the beach in Matalenas Santander, my friend and I saw a dolphin swimming all over the beach and it approached some surfers who were on the shore. After the waves receded, he saw himself surrounded by rocks and ended up heading towards the shore, which was his only escape, and we decided to run down and try to help him since the tide was falling fast and he could see that he was trying to get out of that situation. We decided to put him on the surfboard because we couldn't because of the weight and after advancing a few meters we pushed with everything so he could swim in a deeper depth. When he did, we were super excited and happy that everything went well.
