Primechatelno that many species of these fish form monogamous pairs for a long period of time. That is, the male stays with one female, which experts explain by environmental factors. Every male on the belly there is a special bag. During the breeding season the female throws in this bag with the help of ovipositor their eggs. Eggs could be up to a thousand. After that the offspring bears the male for 9-45 days depending on the species.

When the fry are ready to hatch, the male expels them out of the bag with the help of muscle contractions. Fry can be anywhere from 5 to 1000. They leave the bag at night and in the morning the male is already ready for the next batch of eggs. Under such conditions of birth survives no more than 0.5% of the fish, because, once in the water, they are on their own. But this percentage is quite high compared with other species of fish. In the wild seahorse live 4-5 years.
