American crocodiles have the potential to live as long as 100 years, however their average life expectancy ranges from 60 to 70 years. There is a high mortality rate of offspring. Only 1 in 4 reach the age of 4. This is due to their vulnerability at their hatching size. Young American crocodiles have not yet developed the size and strength necessary to protect themselves from predators. Their vulnerable status along with the lack of parental care puts the young at risk. Also, if nests are built below the water line, flooding can result in mass death of the eggs. In addition, the eggs themselves are at risk to thieves such as raccoons.
