Crocodiles are egg-laying animals. After a period of courtship and mating, which takes place in the water, the eggs are deposited in nests prepared by the mother. She then watches over them until they hatch, in two to three months. The number of eggs in a nest depends on the age and size of the mother, but may range from 30 to 100. The white, hard-shelled eggs are about the same size as chicken eggs, weighing between 1.4 and 3.2 ounces (40 and 90 grams). The eggs are incubated by sun-warmed rotting vegetation placed on them by the mother. When still in the shell but ready to hatch, the crocodilians utter squeaking sounds. The mother, alerted by these sounds, removes the debris covering the eggs, and the young emerge by puncturing the egg with a horny growth on the tip of the snout. The mother provides little further care for her offspring.

Newborn crocodiles are about 8 to 10 inches (20 to 25 centimeters) long and are vulnerable to many predators, including fish, birds, and larger crocodilians. They increase in length about one foot (30 centimeters) per year for their first three to four years. Growth then continues more slowly. Sexual maturity occurs at about 10 years of age. Captive crocodilians may live up to 40 years; those in the wild can live much longer some beyond 100 years.

Crocodiles are predators and are nocturnal that is, active mostly at night. During the day they often lie at the water's edge in large numbers, sunning themselves. At night they retreat to the water, where they live solitary lives and establish individual territories. A resident animal roars loudly at the approach of an intruder. Young crocodiles eat worms and insects. As they mature, they add frogs, tadpoles, and fishes to their diets. Older animals eat mammals and occasionally humans. Crocodiles capture water animals in their jaws. To catch land animals, they knock unsuspecting prey into the water with their long, powerful tails. Animals too large to be swallowed whole are either torn to pieces or are drowned and permitted to decay in burrows. These burrows, which are dug at or just above the waterline, can extend for many feet and eventually end in a den, or chamber.
Threats: Over-fishing
Interesting Information: Adults average size is usually 1.3-2.0 meters (max of 2.6 meters).The first recorded nesting of this crocodile in captivity was in 1981 at the Siliman University Crocodile Breeding Facility where a breeding pair laid 34 eggs, of which 2 were fertile but did not survive.
