What kind of creature is the Zerg in Ender's Game?

Attribute Zerg is a highly evolved race. There are not many descriptions of them in the book. Just mentioned the following points (welcome to add): 1. It is an organic organism similar to human beings. 2. Genetic material is similar to human. 3. Although similar to insects, the endoskeleton has evolved and the exoskeleton has almost completely degenerated. 4. The physiological structure is like ants on the earth, but it has complex professional internal organs. They communicate in a way of distance. 6. What they call individuals is actually just controlled by their mothers. An individual without mother's control will not move like a vegetable. 7. They live in caves. At the end of the evaluation of Ender's Game, Ender once wrote a thin book describing the direct story of Zerg and human beings. There is a passage: "It is written in the tone of the mother of the Zerg, describing their intentions and actions, telling their failures and successes, small and great. We didn't mean to hurt you. We will forgive your death. The book also describes the history from their earliest wisdom to the genocide war. Ender's story is told quickly, just like an ancient legend. When he told the story of Mother Zerg, he did not hesitate to describe it in detail. Mother Zerg is the ancestor of all mothers. She was the first to learn to live in peace with her newborn mother instead of killing or expelling her. She killed her children countless times until she gave birth to a child who could understand her thoughts and live in peace with her. For their world, this is a miracle. The two mothers love each other and help each other instead of fighting each other. On the whole, they are better than all other queens. Their families began to prosper, and more little queens joined them peacefully. This is where the wisdom of the Zerg comes from. If we had communicated with you early in the morning, the Queen Mother said in Ender's book that none of this would have happened. But tragedy has become a fait accompli. We only have one request: please remember us and don't treat us as enemies. We are just a sad sister. Played by the hand of fate. If we can communicate with each other, we will regard each other as rational creatures in the eyes of both sides. However, we kill each other. But we still welcome you to be friendly guests. Go to our homes, children of the earth, live in our tunnels and cultivate our land. What we can't do is up to you now. Trees flourish because of you, and the land is fertile because of you. The sun is warm for you and the planets are prosperous for you: feed them. Humans are our adopted children, and they have arrived home. " Ender said through his mother's mouth, "The trees are flourishing because of you, the land is fertile because of you, the sun is warm because of you, and the planets are prosperous because of you: feed them, humans are our adopted children, and they have arrived home." In fact, the Zerg is a tragic race, and they are related by blood. Even if the universe is a dark forest, we can't be cruel for no reason.
