How do silversides attach their eggs near shore?

Most silversides (family Atherinidae) breed near the shore by attaching their eggs to plants.1

A notable exception is the grunion (Leuresthes tenuis), which exhibits a different spawning behavior. Instead of attaching eggs to vegetation, the female grunion buries them in the sand on the beach during high tide. These eggs remain in the sand until they are exposed by the next spring tide, at which point they hatch.21
