Grunion 2

Grunion 2

The grunion eggs lie dormant in the sand until the next spring high tide, when the eggs are washed back into the sea and the young grunion hatch. The grunion are aware of the day and time of extreme high tide and are able to choreograph a mass exodus to the land and back to the sea. Of the 150 species of grunion, most are found in tropical and temperate seas. [BM] {FW}
