Grunions

Grunions, native only to the shores of Southern California, are the only known fish to lay its eggs on land. Between March and August, they come onshore in large numbers to lay eggs and bury them in the sand. The sand protects the eggs for up to nine days until ready to hatch. It is legal to catch grunions while they are on the beach, but only with bare hands. The preferred method of grunion catching is at night with a flashlight and a gunny sack.
