Estuarine or Salt-Water Crocodile ( Crocodylus porosus )
Estuarine or Salt-water crocodiles are the largest reptiles in the world, in terms of mass. They are found in estuaries, areas of murky water where ocean water and fresh water sources mix. They can survive in both fresh and salt water. They have a short snout and have rows of bony scales protruding along their neck and back. They are a grey/brown color with a lighter, creamy underside.
Distribution & Habitat:
Can be found from Broome, along Australia's west coast up to the Northern Territory and over to Queensland. There is a thriving population in the river systems near Darwin. They spend the wet season in freshwater, swampy areas and move out to estuaries and the sea during the cool season.
Diet:
Salt-water Crocs prey on fish, turtles, birds, reptiles and mammals (ie. dingoes, wallabies, humans, cattle). The crocodile pierces its prey with sharp teeth and then waits for it to die. Once dead, the crocodile breaks the prey into smaller pieces by violently shaking its head.
Breeding:
Salt-water crocodiles breed in the wet season. They lay eggs in nests built made of soil and mud. The female lays between 30 and 60 eggs and then guards the nest for 3 months.
Life Span:
70 to 100 years
Conservation Status:
Not Threatened
