Unlike their human counterparts, bloodsucking leeches fall off once they are engorged. As they reach the point of satiation, they disengage and start to digest their meal. Much maligned and often portrayed in movies and literature as capable of bleeding their hosts to death, these poor annelids from subclass Hirudinea are all carnivorous but only a few are truly bloodsucking brutes ! Their value in medical research and in maintaining nature's delicate balance cannot be overemphasized. Along with other "unloved" creatures like barnacles and sharks and crocodiles and snakes and fungi they know what satiation means and they help us survive and live peaceably in the blue marble. Unfortunately, insatiable, scheming, and power-intoxicated politicians can suck the lifeblood of this nation!
