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. Vocabulary Eliminate Concern Peacock hormone Fan Economy Undertake Dimension (dimension) Counter-example (counter-example) Life style Mandarin duck Reproductive system (genital system) Offspring (offspring) efficiency competition elk strategy (strategy) medical examination (medical examination) destiny pouch tolerant Sexual dimorphism Defense Column consultant/ Dr. Zhang Dake, associate researcher at the Center for Advanced Biomedical Engineering, Beihang University Produced by/ Ke Rongyi Producer/ He Na Co-ordinator/ Wang Xiaoying Chief Writer/ Zhang Zhouxiang Drawing/ Vasily Lee Internship/ Lu Xiaohang and Li Kexin Source: Tutu is the way |
