The best reason for this, in my opinion, might be because there are many, many predators in the ocean so overproduction maybe so that there will still be seahorses who survive. ( I don't know if this is totally accurate to your question but for me, that would be the first idea that comes to mind.) I hope this will help.
Natural selection takes place in particular kinds of populations of species due to various elements. It starts with overproduction. In biology, overproduction means that each generation exhibits more offspring than can be encouraged by the environment.
In the case of seahorse, overproduction takes place due to the limited availability of resources and the threat of predators. The phenomenon of overproduction facilitates to better the genetic line by encouraging the survival of the fittest. As the resources are confined, so those offspring that are best able to adapt to the challenges of the environment possesses the tendency to survive.
