In the animal world, why are males generally better looking than females? | Tutu Science Fiction

Q What animals are born from males? A There is only one species of seahorse. The survival rate of seahorses is too low. They need to reproduce more offspring quickly. Female seahorses lose to male seahorses in fertility from the beginning because they do not have a brood pouch. The brood pouch on the abdomen of male seahorses can fertilize eggs. Before the baby seahorses mature, they will be cared for and fed by the "father". When the baby seahorses mature, they will be put into the sea by the "father" to start a new life journey.
