In the animal kingdom, survival often depends on numbers. While some creatures nurture just one or two young, others bring dozens (or even millions) of offspring into the world at once. These creatures rely on producing astonishing numbers of offspring in a single reproductive event, flooding their environment with babies in the hopes that a few will make it to adulthood. From the smallest insects to the giants of the sea, these prolific breeders ensure their survival through sheer reproductive power.
