Sihwa repeatedly expressed her enthusiasm for the rest to eat the fish. She invited Zhang Zian and the others to eat. She claimed that the fish had had too much sun and had heat stroke. She did not seem to have given much thought to whether the fish agreed with her.
Although Zhang Zian had never eaten a lungfish before, he really wanted to know how it tasted and if it had thorns on its skin. He'd never had the chance to taste such an expensive delicacy. Thus, to him, eating this fish would be like eating money!
In order to adapt to the changing environment in Africa, ancient fish had evolved a unique means of survival. When the environment was dry, they would dig holes in the soil and use mud and secreted mucus to form a protective shell to prevent water loss. Only a thin tube in their mouth was used to breathe.
Although they had lungs, they still needed to emerge from the water every half an hour to breathe. Otherwise, they would die.
