"It's about sixty to seventy years." Shen Mochen replied lightly, and then continued to ask, "Then do you know how long the dolphins in the aquarium can live?" ”

"Fifty years?" Momoko thought for a moment and looked at him uncertainly.

Shen Mochen shook his head gently, a pair of ink-jade eyes stared closely at Peach's innocent eyes, and his voice was distant as if it was floating from the sky, and said lightly: "Wrong, about eight years." ”

"So short?" Momoko's eyes were full of astonishment, "Why?" ”

"Because the smile of the dolphin is nature's most clever camouflage." Shen Mochen sighed deeply, looked at Peaches with some unbearability, and continued: "When we watched the dolphin show in the aquarium, most people were deceived by their smiles, but in fact they were not happy. ”

"Dolphins are very sensitive animals with a well-developed auditory system that can distinguish sounds from low sound waves to ultrasound in a wide range of sound waves, so their hearing is a thousand times sharper than ours. Because they are extremely sensitive to sound, the sound of music, cheers from the audience, and all sorts of small noises when dolphins are captured by humans and imprisoned in the aquarium for amusement shows is a constant auditory torture for them. ”

Shen Mochen paused, glanced at the noisy crowd around him, frowned and continued: "The huge pressure and harsh sound of the performance caused most of the dolphins to suffer from stomach ulcers, and they had to rely on medication. Even a normal person would go crazy in a highly noisy environment, let alone a dolphin. ”

"......" Peach was silent, she never knew that the dolphins were actually performing with their lives, and she didn't know that such a performance turned out to be a pain for the dolphins, she raised her head and looked at Shen Mochen's eyes that were slightly blocked by the hair on her forehead, there was deep pity in them, no wonder he frowned when he said that he was going to see the dolphin show, she thought he hated the crowd, no wonder he was expressionless when people applauded and shouted hard, It turned out that he had known for a long time that this was a harm to the dolphins.

When life becomes so heavy in captivity, when they can no longer swim in the vast ocean at a speedboat speed of 40 kilometers per hour, when they can no longer dive to the depths of the ocean to frolic and play, they will also be depressed, depressed, depressed, and will resist with death.

Richard O'Berry, who was once the world's top dolphin trainer, saw with his own eyes that one of his domesticated dolphins chose to commit suicide. The dolphin, named Casey, swam into Richard's arms, looked him in the eye, took a breath, and then stopped taking a second breath......

Unlike humans, dolphins and other cetaceans' breathing does not take place automatically. Therefore, every breath is a conscious effort for them. So, when they don't want to be under the pressure of survival anymore, they don't breathe in the next breath of air, and that's the dolphin's suicide.

Momoko suddenly became depressed when she learned all this.
