Evolution tries everything.

Most animals require close contact to reproduce, using either internal
fertilization (as humans do) or fertilization nearby (think spawning
salmon). So having a similarly matched body size is helpful for
reasons of physical logistics—as well as for personal safety (as we’ll
soon see). But for causes still obscure to most—except Evolution
herself—in a very few, very distantly related animals, males and
females long ago diverged to two radically different scales.
