Seahorses –
In the world of seahorses, the females are equipped with a penis like ovipositor (organ to lay eggs with) which she inserts into the males egg pouch where the male fertilize the eggs and as a result the male gets pregnant. It is believed they evolve this way so the young would be protected by the male while the female uses energy on producing more eggs that way when the young are born the parents are ready to mate again sooner.
While seahorses do not mate for life, they are very faithful, loving and gentle in the days up till the actual mating, and while the male is pregnant the female will visit him every day to gently touch him and simply spend time with him.
