Saltwater crocodile / "saltie"  

Photos & text by Dr. Robert Sprackland.

 

Range: Much of tropical southern Asia east to Australia and the Solomon Islands.

Diagnosis: A large crocodile with a broad snout and two pair of central and isolated large scutes on the nape (with a smaller scute on the lateral portion).

Description: This is the most massive of living reptiles, with males approaching 7 m (23 feet) and weighing up to 1500 kg (3300 lbs.).

Natural History: A large and powerful predator that is also a confirmed human-eater. Attacks on humans are most likely to occur in developing countries and in parts of Australia where tourists disregard crocodile warning signs. An attacking crocodile can easily leap upwards almost clearing the entire body from the water, and on land can outrun humans for several dozen meters.

The name "saltie" comes from the habitat preference of this species for marine or brackish water, and they often prowl reefs in search of food. They have been observed swimming many scores of miles from land and are thus able to colonize such a great geographical range, spreading from India and Sri Lanka to the Solomon Islands and eastern Australia.

The natural diet consists largely of fishes and water birds, but the crocodiles will consume any prey they can overpower. At their size and weight, that leaves relatively few species immune to a possible crocodile attack.


Well known Steve Irwin, "The Crocodile Hunter," and one of his charges at Australia 
Zoo. Though a consummate showman, Steve also readily acknowledges that crocs
are very predictable in habits and responses to certain stimuli.

Reproduction: Salties lay eggs in large mounds of composting vegetation that are formed by the females. Both parents will protect a nest and hatchlings.
