Diminutive annual killifish take refuge in small pools and puddles left
on the forest floor as the floodwaters recede. They lay their eggs in
the wet, muddy leaf litter. As standing water evaporates, the adult killifish
are stranded and die, but their eggs survive on the moist floor and hatch
months later when the rains come again. The babies mature rapidly during
high water, reproduce and die, completing the species' annual cycle within
the river's yearly rhythms.
