Their eggs and meat are eaten, and their skin is particularly valuable for use as a material for bags, shoes, and other goods. Recent conservation efforts have allowed populations to rebound in some places, but the historic range has certainly contracted, as a result of local extinction.
Currently, the saltwater crocodile has complete legal protection in Australia and other places. However, it is important to further monitor saltwater crocodile population trends to ensure that the recent positive trend continues to support recovery of this top coastal and marine predator. Saltwater crocodiles are the largest crocodile species in the world, and the largest living reptile in the world. Male saltwater crocodiles have been recorded at lengths of 23 feet 7 m and weights of 2, pounds 1, kg.
Females are much smaller, growing to be about 10 feet 3 m long and weighing pounds kg. Adult saltwater crocodiles have 66 teeth on average and the greatest bite pressure of any animal in the world. Saltwater crocodiles are most commonly found in coastal waters or rivers where they can swim between freshwater and brackish water. Follow us on Instagram at natgeoyourshot or visit us at natgeo.

To do that, the ocean-trotter hitched a ride on a current within the Gulf of Carpentaria that separates Cape York from Arnhem Land, to the west. This current occurs seasonally, during the summer monsoon. It took another adventurer - a 4. When the crocodile arrived in the Torres Strait, strong currents were flowing in the opposite direction to where it was headed.
So the animal waited in a sheltered bay for four days and continued its trip when the currents changed direction. The scientists also tagged 27 crocodiles with sonar transmitters and spent a year tracking their every move inside the North Kennedy River with underwater receivers. They found that both male and female crocodiles regularly travelled more than 50km from home, swimming to the river mouth and back.
After they made their discovery on the river, Campbell and his colleagues re-analyzed archival data from the few crocodiles that have been satellite tracked while undertaking ocean travel. By overlaying the reptiles' movements with surface current estimates, they found the strategy of ocean-swimming crocodiles was similar to what they employed with rivers. One satellite-tagged crocodile, Another croc — a When the reptile arrived at the straits, the currents were moving opposite to his direction of travel — he then waited in a sheltered bay for four days and only passed through the straits when the currents switched to favor his journey.
