The reason why the hippocampus is born by the father is that the father has the structure of parenting sac, while the hippocampus mother does not have such a structure, so it cannot provide protection for the hippocampus baby. Usually, after sexual maturity, the female hippocampus will release the egg into the parenting bag of the male hippocampus, where it will combine with the sperm of the male hippocampus to form a fertilized egg, which will slowly hatch into a small hippocampus, and then the male hippocampus can give birth to it.

1. Mating: The hippocampus must mate first when giving birth to children. One of the characteristics of hippocampal mating is that females inject eggs into males, and then males complete the process of fertilization. Usually, other creatures in nature are fertilized by eggs from males to females. In the seahorse, however, it is completely reversed.

2. Hatching: Hatching of hippocampus is also its characteristic. Unlike many fish that hatch directly in the wild environment, seahorses have special pouches, so their eggs will be safely protected, so that they will not encounter the bad luck of being eaten, thus improving their reproductive success rate. In addition, seahorses have pouches only for males.

3. Production: The production of hippocampus is the most characteristic. Because it is the only animal on the earth that is bred by males, as mentioned above, after the eggs in the pouch hatch, the male seahorse will produce them, which usually takes 50-60 days to hatch.
