Because only male seahorses have brood sacs and can reproduce, seahorses are born from their father.

The reproduction method of seahorses is very special, because the baby seahorses are produced by their father. The fact that seahorses cannot be born by their mothers is determined by the body structure of seahorses, because female seahorses do not have a brood sac in their body structure, only males have it.

This structure is necessary for the gestation of a baby seahorse. Only here can it provide the necessary nutrients for the development of the baby seahorse embryo. Therefore, this results in only seahorse dads being able to produce calves.

Habits of seahorses

Seahorses live in places where algae thrive in the sea, usually in offshore areas with moderate wind and waves. The seahorse is a shallow-sea fish with low mobility. Its locomotion organs are mainly fins, mainly relying on the cooperation of the pectoral fin, dorsal fin, and anal fin. The seahorse uses it to slowly swim for food, reproduction or avoid harsh environments, and it also has the ability to curl. The tail can be wrapped around seaweed or other floating objects in search of food or for other purposes.

Usually, seahorses have two swimming postures. One is that the body is straightened almost horizontally, so that it swims faster, and the other is that the body is almost vertical when swimming with its tail curled. The speed is slow, generally swimming at a speed of 1 to 3 meters per minute. Seahorses have strong adaptability to changes in water temperature. The suitable temperature is 9-33°C. Seahorses are prone to death beyond this range.
