Quizplus · Accepted Answer

Grunion lay their eggs in the sand during high tide, and the hatching of the eggs is dependent upon the sand being in the proper state of erosion and deposition. If the sand is too eroded or too deposited, it can affect the hatching success rate of the eggs. Therefore, the survival of grunion eggs is closely tied to the pattern of sand movement along the shore.
