Folks:  An interesting question was recently asked me by a student:  some
fish have large 'eye spots' on their tails (e.g., bowfin, some reef fishes,
red drum, oscars) - how common is the caudal fin eye spot (i.e., what other
species exhibit this), and in what species does the size/color/presence of
the eye spot differ among individuals (between the sexes, between the
sizes/ages, as a function of season, with dominance/subordinance)?  A good
question, for which I don't have a ready answer.  Your thoughts?  Doug
