Concurrent daily measurements of environmental variables and embryo survival were made for two atherinid fishes, the California grunion, Leuresthes tenuis, observed at Blacks Beach, La Jolla, California; and the Atlantic silverside, Menidia menidia, observed at the Point of Pines, Edisto Island, South Carolina. Measurements were made during April 1980. Both species spawned in the upper intertidal zone on high tide. L. tenuis eggs were deposited approximately 4 cm below the beach surface during nightime. Subsequent sand deposition buried embryos to a depth of approximately 8 cm where they were protected from thermal and desiccation stresses. Daily survival of incubating embryos averaged 97%.
