Eating Habits:The saltwater crocodile is an opportunistic predator capable of taking nearly any animal that enters its territory, either in the water or on dry land. Juveniles are restricted to smaller animals such as insects, amphibians, crustaceans, small reptiles and fish. The larger the animal grows, the greater the variety of animals it includes in the diet, although relatively small prey make up an important part of the diet even in adults. Large adult saltwater crocodiles can potentially eat any animal within its range, including monkeys, kangaroos, wild boar, dingos, goannas, birds, domestic livestock, pets, water buffalo, gaurs, sharks, and even humans, among other large animals as well. Domestic cattle, horses, water buffalo and gaur, all of which may weigh over a ton, are considered the largest prey taken by male crocodiles.It can survive for monthes without food.

Breeding: Saltwater Crocodiles mate in the water and females lay 40 - 60 eggs in a mound of vegetation on the river bank. The female will guard the eggs for approximately 100 days and upon hatching the young crocodiles will squeal and their mother will dig them out and carry them into the water. For the next 8 months the young crocodiles will live in creche groups that are watched over by the adults.

Located: Southeast Asian and North Austrailia

Historic/ current range: The modern day crocodile has been around for 65 million years. The first crocodiles were on the earth 200 million years ago.

Habitat: During the wet season they spend their time in fresh water swamps and rivers but during the dry season they move down stream to estuaries and can sometimes be seen in the open sea. They are territorial and dominant males tend to occupy the most eligible areas of rivers and freshwater streams.

Are they migratory? YES

Above/ below ground: above ground or below water.

Hibernation: during winter

Predators/symbiotic relationship: Humans./ none

Problems: They are largely hunted for their meat and skin.

Solutions: Congress made these solutions to protect the species of saltwater crocodile. They are the Endangered Species Preservation Act of 1966, the Endangered Species Conservation Act of 1969, and the Endangered Species Actof 1973. Australia has several breeding programs for the saltwater crocodile so they can use those crocs for skin and meat. They also have conservation programs that not only preserve the crocodiles, but also their habitats.
