Gavialis gangeticus / Crocodylus niloticus
Gharial vs Crocodile
Gharials and crocodiles are both crocodilians, but the gharial has an extremely narrow fish-catching snout and is harmless to people, while the broad-snouted crocodile is a powerful generalist predator that can be dangerous.

Overview
The gharial, Gavialis gangeticus, and the crocodile, represented here by the Nile crocodile Crocodylus niloticus, are both members of the order Crocodilia but belong to different families, Gavialidae and Crocodylidae.
The most obvious difference is the snout. A gharial has an extremely long, thin snout lined with more than a hundred interlocking needle-like teeth, ideal for catching fish. A crocodile has a broad, powerful snout and jaws suited to seizing large prey. Adult male gharials also grow a rounded lump of tissue on the snout tip called a ghara, which no crocodile has.
Size
Both are large reptiles. Gharials measure about 2.6 to 6 metres, and large old males are among the longest of all crocodilians, though they are relatively slender. Nile crocodiles are shorter on average, roughly 3.5 to 5 metres, but far heavier and more heavily muscled for their length.
In short, the gharial can match or exceed the crocodile in length while the crocodile wins decisively on bulk, bite force, and raw power.
Behavior
Both bask to control body temperature and are strong swimmers that use the tail for propulsion. The gharial is highly aquatic and moves awkwardly on land, usually only hauling out to bask and nest. The crocodile is more mobile on land and can make fast lunges from the water's edge.
The key practical difference is danger to people. Crocodiles, including the Nile crocodile, are powerful ambush predators responsible for attacks on humans. Gharials, with their narrow fish-catching jaws, are essentially harmless to people.
Diet
The gharial is a fish specialist. Its slender snout slices through water with little resistance, letting it sweep sideways to snap up fish, with crustaceans and insects taken by juveniles. The crocodile is a generalist that eats fish, birds, and mammals, ambushing animals that come to drink and scavenging carrion.
Their teeth reflect this: the gharial's thin, even teeth grip slippery fish, while the crocodile's stout teeth hold and tear large struggling prey.
Habitat
Both live in fresh water, but on different continents. The gharial survives in a few clean, fast-flowing rivers of India and Nepal, needing deep pools and sandbanks for nesting. The Nile crocodile occupies rivers, lakes, and wetlands across much of sub-Saharan Africa.
Their conservation stories differ sharply. The Nile crocodile is listed as Least Concern and remains widespread, while the gharial is Critically Endangered after a severe population collapse, and survives largely thanks to river sanctuaries and captive breeding.
