ilah Posted June 9, 2009 Report Share Posted June 9, 2009 The only thing i have heard which makes sense (if i remember rightly) is that males supposedly have an undershot jaw. Im sure it had somethin to do with males picking up and holding the eggs....maybe? haha Quote Link to comment Share on other sites More sharing options...
