The Seahorse Father Gives Birth

I found this interesting post I thought you might like, From Quora https://www.quora.com/

The hard labor, the pushing, the expulsion: this is a gif of the happy event of one of the animal world's most present and caring fathers: the male seahorse (yes, it is the seahorse father that give birth, in a rare natural case of male pregnancy).

During mating, the female lays eggs in a special incubator pouch located in the male's belly. The partner fertilizes and houses them for the duration of the larval stage, which ends after about 28 days. Birth occurs about a week later: in a series of rhythmic and violent contractions, reminiscent of those of human birth, the fish expels 20 to 1,000 miniature hippocampi, about 7 millimeters long.

“Loyal” creatures.

The absolute faithfulness of seahorses was discovered by a group of researchers at the University of Melbourne a few years ago. Among the more than 50 pairs of seahorses kept under observation for 135 days by Laila Sadler and her research team, there was not a single case of cheating. Every morning male and female would meet shortly after sunrise always in the same spot and spend a few moments together. As soon as the pregnancy was over they would pair up again. The only cases of changing partners occurred following the death of the "spouse."
