What is a "freshwater crocodile"?

A freshwater crocodile, also known as the Australian freshwater crocodile or Johnstone's crocodile, is a species of crocodilian that inhabits freshwater environments such as rivers, lakes, and swamps in northern Australia. They have a smaller and more slender build compared to their larger relative, the saltwater crocodile, and are well adapted for swimming and catching prey in aquatic habitats. Despite their smaller size, they are still powerful predators and play an important role in the ecosystems they inhabit.
