It is interesting to contrast Shylo K. Akuna's conviction and sentence with the fate of the prep school kids who slaughtered the Laysan Albatrosses and destroyed their nests.  Should we believe a difference in age of just two years makes all the difference in the world?  Akuna, as despicable as his act was, didn't actually kill the endangered monk seal.  Perhaps then, the penalty you face for harassing or killing an endangered creature depends on the specific endangered creature.
