"The pressure of growth among animals is a kind of terrible hunger. These billions must eat in order to fuel their surge to sexual maturity so that they may pump out more billions of eggs. And what are the fish on the bed going to eat, or the hatched mantises in the Mason jar going to eat, but each other? There is a terrible innocence in the benumbed world of the lower animals, reducing life there to a universal chomp. Edwin Way Teale, in The Strange Lives of Familiar Insects—a book I couldn't live without—describes several occasions of meals mouthed under the pressure of a hunger that knew no bounds."
