Abstract

This paper makes some additional points about matters discussed in my book „Aristoteles als Naturwissenschaftler“ (Aristotle as a Natural Scientist), Berlin 2014. Findings by the biologist A. M. Leroi, who published a book on Aristotle with a similar subject that same year („The Lagoon. How Aristotle invented science“), will be considered. It will be argued that the mayflies discovered by Aristotle in the Kuban River belong to the species Palingenia fuliginosa. Aristotle is more likely to have observed the life-history of the catfish in the river Strymon in Northern Greece than in the Achelous river basin in Acarnania. He probably never set eyes on the catfish Silurus aristotelis, which is endemic to Acarnania and was discovered by Agassiz in 1857.
