* Weight: Saltwater crocodiles are generally heavier. Adult males can weigh up to 2,200 pounds (1,000 kg), while the largest great white sharks documented weigh around 5,000 pounds (2,300 kg). However, these are extreme outliers, and the average weight of a large saltwater crocodile is likely to be around 1,000 pounds (450 kg) compared to 1,500 pounds (680 kg) for a large great white shark.
* Length: Great white sharks are generally longer. The longest recorded saltwater crocodile measured 23 feet (7 meters), while the largest great white shark recorded was a staggering 20 feet (6 meters) long. However, it's worth noting that the crocodile's tail is much thicker and longer than the shark's, so they can be quite similar in overall length.
* Power: Saltwater crocodiles are generally considered more powerful. They have incredibly strong bite forces, estimated at 3,700 pounds per square inch (2500 kg/cm2), which is the strongest bite force of any animal on Earth. Great white sharks, while incredibly powerful, have a weaker bite force of around 4,000 pounds per square inch (2800 kg/cm2).
So, which is bigger? It depends on what you're looking for.
* Heavier? Usually the saltwater crocodile.
* Longer? Usually the great white shark.
* More powerful? The saltwater crocodile, thanks to its incredible bite force.
Ultimately, both animals are incredibly large and powerful apex predators, and it's hard to say definitively which is "bigger" without context.
