Abstract: The mass, length and breadth of 572 eggs of Alligator mississippiensis were measured and described as a complete sample and as subsets of 14 clutches. Egg volume and density were calculated. A multiple regression equation was generated to predict initial egg mass from egg length and breadth. A weight coefficient (KM) was determined for alligator eggs and its value was compared both to published values for avian eggs and to values for other crocodilian eggs calculated from literature data. The value of KM in crocodilians was higher than in avian eggs implying that the density of alligator eggs was much higher than the density of avian eggs. Egg volume in alligators was also estimated using the volume coefficient (Ky) for avian eggs but this was found not to be applicable.
