Fishy Facts ( sorry )

Its been good to get out this afternoon, really good. I haven't felt completely well for at least a couple of months. My energy has been sapped, but today I guess the anti-biotics Im taking are finally working. I think ive been harbouring something in me that's been draining my energy for sometime. Anyway I visited an Aquarium  this afternoon ( they also had insects ) and learnt some alarming facts ! 

Seabass all start their lives in the sea as FEMALES, and only when a dominant male dies does a chosen female then change her sex to  MALE, hence replacing him and becoming the shoals new leader ! So I guess that old adage " The king is dead, long live the king " has gained a whole new twist ! I wonder what triggered this evolution ? I shall not start making human comparisons though, don't panic..
