Apparently the female seminal receptacle is also very long. In fact, the increasing length of this receptacle is one of the explanations for the extreme sperm length.
Drosophila females have evolved to fertilize their eggs with particularly long sperm. Only large, healthy males are able to produce large quantities of gigantic sperm, and if a female reproduces with healthy males, her offspring will have genes that make them healthy, too.
Just wanted to comment, cause this community is a bit quiet. But man, I really hate tier lists. Just enjoy what you enjoy.
Like, Unseen Academicals and The Last Hero are some of my favourites.
I haven't read the Tiffany Aching books. Just cause I don't read much YA stuff. Maybe one day... In many discworld groups people really seem to enjoy them. And I've heard they are great for younger readers too.
