The adult saltwater crocodile's broad body contrasts with that of most other lean crocodiles, leading to early unverified assumptions the reptile was an alligator. [30] Young saltwater crocodiles are pale yellow in colour with black stripes and spots on their bodies and tails.
The saltwater crocodile is considered to be the largest extant reptile, verified at up to 6.32 m (20.7 ft) in length and around 1,000–1,500 kg (2,200–3,300 lb) in mass. [2] Larger specimens have been reported albeit not fully verified, [ 3 ] the maximum of which is purportedly 7 m (23 ft) long with an estimated mass of 2,000 kg (4,400 lb).
The American crocodile (Crocodylus acutus) is a species of crocodilian found in the Neotropics.It is the most widespread of the four extant species of crocodiles from the Americas, with populations present from South Florida, the Caribbean islands of Cuba, Jamaica, Hispaniola, [4] and the coasts of Mexico to as far south as Peru, Ecuador, Colombia, and Venezuela.
Freshwater crocodile at Australia Zoo. Until recently, the freshwater crocodile was common in northern Australia, especially where saltwater crocodiles are absent (such as more arid inland areas and higher elevations). In recent years, the population has dropped dramatically due to the ingestion of the invasive cane toad.
Thalattosuchia is a clade of mostly marine crocodylomorphs from the Early Jurassic to the Early Cretaceous that had a cosmopolitan distribution. [3] They are colloquially referred to as marine crocodiles or sea crocodiles, though they are not members of Crocodilia and records from Thailand and China suggest that some members lived in freshwater.

Growth in hatchlings and young crocodilians depends on the food supply. Animals reach sexual maturity at a certain length, regardless of age. Saltwater crocodiles reach maturity at 2.2–2.5 m (7–8 ft) for females and 3 m (10 ft) for males. Australian freshwater crocodiles take ten years to reach maturity at 1.4 m (4 ft 7 in).
A smaller species of crocodile with a grey-brown colour and dark brown to black markings on the tail. The young have a narrower V-shaped snout that becomes wider as the animal matures. Prefers freshwater habitats, even though is tolerant to salt water, in order to avoid competition and predation by the saltwater crocodile. This species feeds on ...
Reviews indicate that at least half of all attacks by the Nile and saltwater crocodiles are fatal [1] (in Australia, however, only about 25% of saltwater crocodile attacks are fatal). [3] The mugger crocodile is also very dangerous to humans, killing several people in India every year and with a fatality rate that is almost as high (slightly ...
