The freshwater crocodile (Crocodylus johnsoni), also known as the Australian freshwater crocodile, Johnstone’s crocodile or colloquially as freshie, is a species of reptile endemic to the northern regions of Australia.
Unlike their much larger Australian relative the saltwater crocodile, freshwater crocodiles are not known as man-eaters and rarely cause fatalities, although they will bite in self-defense if cornered.
The freshwater crocodile is a relatively small crocodilian. Males can grow to 2.3–3 m (7.5–9.8 ft) long, while females reach a maximum size of 2.1 m (6.9 ft). Males commonly weigh around 70 kg (150 lb), with large specimens up to 100 kg (220 lb) or more, against the female weight of 40 kg (88 lb). In areas such as Lake Argyle and Katherine Gorge there exist a handful of confirmed 4 metres (13 ft) individuals. This species is shy and has a more slender snout and have slightly smaller teeth than the dangerous saltwater crocodile.
The body colour is light brown with darker bands on the body and tail—these tend to be broken up near the neck. Some individuals possess distinct bands or speckling on the snout. Body scales are relatively large, with wide, close-knit armoured plates on the back. Rounded, pebbly scales cover the flanks and outsides of the legs.
