The maternal brilliance of ehrlich, the mother of tree frog, is dazzling among frogs. Ai's mother went back to the tree hole to feed, of course, not to nurse, because they are not mammals; They don't have food in their mouths like birds. When Mama Ai returned to the tree hole, her lower body was soaked in the water, and tadpole dolls began to peck around Mama Ai's cloaca to stimulate Mama Ai to lay eggs. This is the feeding way of tree frog Ai. Tadpoles in ehrlich, a tree frog, really grew up eating eggs, and they all developed the ability to eat eggs. When Ai's mother laid eggs, tadpoles scrambled to tear open the egg sac with their thick beaks, then sucked the eggs and absorbed them quickly. The mouthparts of tadpoles are cleverly designed. Their cheek muscles are particularly strong. When the upper and lower beaks close, there is always a hole in the middle. The whole oral structure looks like a natural smoking device.
