I might add that although Naked Lunch is a surrealistic novel, there is ample reason to make a presumption of veracity with respect to the anecdote about the jungle rat because a number of other lusus naturae referenced in the novel—(such as the candiru: a tiny eel-shaped fish found in the Amazon basin that swims up-river on the scent of urine and lodges itself by means of its barbed head into the uretha of its unfortunate host)—a bit of looking round has proven to be based almost entirely on fact.
