I just want to point out Candiru is a fish that supposedly wriggles up someone's ding-dong when they pee in Amazonian rivers while swimming? I'm... gravely... skeptical that it ever actually happens, if I were to guess it's one of those, "I fell on it while getting dressed" situations that are occasionally explained to amused ER doctors. Maybe even one of those, "they put a chemical in the pool that makes the water turn purple when you pee." Whatever the deal with Candiru is, at some point someone suggested naming their spyware after the urethra fish. They might be making the world a worse place, but you can't say they don't have a sense of humor about it.
