Gulf Grunion Beach Spawning
In Sonora, Mexico, thousands of Gulf Grunion fish act on a seemingly suicidal desire to breed out of water. The female grunion deposit eggs in the sand as far from aquatic predators as possible. The eggs remain buried in the wet sand and hatch in about 10 days, at which point the young grunion make their way back into the water.
