I have no idea on their lifespan. I always viewed them as a step previous to
non-nucleated RBC's (which only mammals have). As far as I can figure, they
are less effective in carrying oxygen (part of their volume is occupied by
the nucleus) and are less flexible (thus more fragile) and offer more
resistance to flow than mammal RBC's.
