Grunions lay their eggs on land to protect them from aquatic predators and environmental threats. During specific spawning seasons, they emerge onto sandy beaches to deposit their eggs in the sand, where they remain buried until they hatch with the next high tide. This unique reproductive strategy ensures a higher survival rate for the eggs by utilizing the safety of the terrestrial environment.
Most fish lay eggs in water, either attaching them to plants or structures or releasing them into the water. Some fish, like salmon and herring, migrate upstream to spawn in freshwater before returning to the ocean. There are a few exceptions, like the mudskipper, which is able to lay eggs on land.
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. The California Department of Fish & Game has an excellent web page on grunions.
Grunions spawn on sandy beaches along the coast of Southern California and Baja California, particularly during spring and early summer. They typically come ashore at night during the high tide to lay their eggs in the sand. The eggs are then covered by sand and will hatch after a few weeks, coinciding with the next high tide. This unique spawning behavior makes grunions a fascinating subject for both marine biologists and beachgoers.
Most reptiles do not lay eggs in water. They typically lay their eggs on land, either in burrows or nests dug into the ground. However, some turtles do lay their eggs in sandy areas close to water, where the eggs can be protected.
