Breeding / Reproduction
The males of the saltwater crocodile reach sexual maturity at the age of 16 years or when they grow up to a size of 10.8 feet. Whereas, the females reach sexual maturity either at the size of 7.5 feet or at the age of about (12 to 14) years. The courtship in these species takes place in September and October. The females make nest between November and March for laying their eggs. The number of eggs varies from (40 to 60). These eggs measure around (80mm x 50mm). The sex of the hatchlings depends on the temperature. The males produced at a temperature of around 31.6 degree Celsius and the females are produced at the temperature little less than that. The incubation period is of about 80 days and the hatchlings measure about 29 cm in length. The female guards the eggs until it hatches and when the hatchlings are produced, the females take it to the water. After that the females remain with the hatchlings for several months in order to protect them from their predators. The 80% of the eggs die during incubation and only 1% reach up to maturity. The rest 19% are eaten by their natural predators like fish, birds and other adult crocodiles.
