More generally, virtually every new persistent mechanism (e.g., species) will create new potential niches by the fact of its existence. This can be seen by considering energy flows. Every persistent mechanism requires a way to exploit energy resources in order to persist. No mechanism is 100% efficient. So every persistent mechanism leaves in its wake some unused energy--often in a form that didn't exist previously That unused energy is then a niche that some other mechanism can exploit. To take Stu's example, the unused energy is whatever it is that bacteria in fish bladder live on.
