Are there female animals in nature who don't get to mate at all?

Many any animals can give birth without mating.
The Sea horse impregnate their male mates rather than the other way around. by dancing together “They’re every woman’s dream,” One male sea horse endured seven consecutive 21-day pregnancies in a single year!
As the baby sea horses lie nestled deep within the brood pouch of the male a rich network of blood vessels supplies them with oxygen and nutrients. When the time for birth arrives, the father’s labor may last from several hours to two days. Finally, his pouch opens, and the sea-horse babies are progressively ejected into the world. The number of babies born varies with the species but can range as high as 1,500.
Another species are the Sea dragons male and female swap roles.
