What creature best embodies that unity is strength? Tell me your reasons.

I think it is an ant. I heard a story. On an expedition, I saw a group of migrating ants by the river in the tropical rain forest, but the road was blocked by the river, so the ants gathered around the queen ant and rolled into the river. The ants outside died one after another, but in the end they succeeded in crossing the fast-flowing river. The little ants are so United and not afraid of sacrifice, which impressed the expedition members deeply. So I think ants are the most United.
