Heptamegacanthus is a genus of acanthocephalans (thorny- or spiny-headed parasitic worms) containing a single species, Heptamegacanthus niekerki. This worm is a parasite of the endangered giant golden mole (example pictured) found only in isolated forests near East London and in the Transkei, both in South Africa. The worms are about 4 millimetres (0.2 in) long and 2 millimetres (0.08 in) wide with minimal sexual dimorphism. Their body consists of a short trunk and a proboscis with 40 to 45 hooks arranged in rings, which are used to pierce and hold the rectal wall of its host. The life cycle of H. niekerki remains unknown; however, like other acanthocephalans, it likely involves complex interactions with at least two hosts. Although the intermediate host for Heptamegacanthus is not definitively identified, it is presumed to be an arthropod, such as an insect, which is eaten by the giant golden mole. The worms then mature and reproduce sexually within the mole's lower gastrointestinal tract, creating eggs which are released in its feces.

I don’t share this heresy. I’m too afraid! But I put it in a play called This Extraordinary Brothel, in which the protagonist doesn’t talk at all. There is a revolution, everybody kills everybody else, and he doesn’t understand. But at the very end, he speaks for the first time. He points his finger towards the sky and shakes it at God, saying, “You rogue! You little rogue!” and he bursts out laughing. He understands that the world is an enormous farce, a canular played by God against man, and that he has to play God’s game and laugh about it. --Eugène Ionesco <https://en.wikiquote.org/wiki/Eug%C3%A8ne_Ionesco> _______________________________________________ Wikipedia Daily Article mailing list.
