The Great White Shark
Marine biologists constantly tracking great white sharks consistently document that the ocean’s most formidable apex predators are overwhelmingly female. Adult males peak around eleven to thirteen feet, but you will find mature females regularly pushing fifteen to twenty feet in length and heavily weighing over two solid tons.
This size discrepancy illustrates fecundity selection in marine environments. Female great whites do not lay eggs; they gestate embryos internally through a biological process known as oophagy, where developing pups consume unfertilized eggs in the womb for nourishment.
To physically accommodate a litter of up to fourteen fully developed, highly active pups—each already four feet long at birth—the mother desperately requires massive internal volume.
