Happy Monday everybody! It’s day 4 of knowledge November with cool croc facts.
Crocodilians, like their avian cousins, are egg layers as oppose to giving live birth like some reptiles.
They nest once a year and certain species can lay as many as up to 80 eggs in one clutch. Even if all 80 eggs were to hatch, the survival rate from a hatchling to a sexually mature reproducing adult is incredibly low. The chances of more than one surviving are minimal.
Most get picked off by larger predators, some will fall victim to inherent illness or anomalies in their health, and some just don’t have the necessary survival skills like the ability to hunt efficiently.
It truly is survival of the fittest which is why crocodyliforms have roamed this earth for millions and millions of years.
