Gulf Grunion Fish Breed Out of Water | Nature on PBS

These 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 female excavates sand on the bead with her tail to deposit eggs, ready for the male grunion milt. 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.
