The annual Killifish are known for this method of reproduction. As the pools where they live dry out, the fish spawn. Pressing their eggs into the substrate. The pools dry out completely and the adults die, but the eggs remain in the dried mud. When the rains return and the pool refills the eggs hatch and the cycle is repeated.
Killifish eggs can stay viable for many years in the dried out mud.
The livebearers do not lay eggs at all, they are fertilized internally and carried to term inside the mothers body. The broods are small and the fry are well developed when born. The Guppy swordtail and Platy are the best known members of this group.
