The bite force exerted by an adult Nile crocodile has been shown by Brady Barr to measure 22 kN (5,000 lbf). However, the muscles responsible for opening the mouth are exceptionally weak, allowing a person to easily hold them shut, and even larger crocodiles can be brought under control by the use of duct tape to bind the jaws together.

The jaws can bite down with immense force, by far the strongest bite of any animal. The force of a large crocodile's bite is more than 5,000 lbf (22,000 N), which was measured in a 5.5 m (18 ft) Nile crocodile, in the field; [66] comparing to 335 lbf (1,490 N) for a Rottweiler, 800 lbf (3,600 N) for a hyena, 2,200 lbf (9,800 N) for an American ...
The black caiman (Melanosuchus niger) is a crocodilian reptile endemic to South America.With a maximum length of around 5 to 6 m (16 to 20 ft) and a mass of over 450 kg (1,000 lb), [6] it is the largest living species of the family Alligatoridae, and the third-largest crocodilian in the Neotropical realm.
Cladistically, it is defined as Crocodylus niloticus (the Nile crocodile) and all crocodylians more closely related to C. niloticus than to either Alligator mississippiensis (the American alligator) or Gavialis gangeticus (the gharial). [5] This is a stem-based definition for crocodiles, and is more inclusive than the crown group Crocodylidae. [3]
[138] [139] Based on the regression of mean body mass and mean bite force, the bite forces of multiple crocodile species, 1,308 kg (2,884 lb) individuals were estimated at 27,531 to 34,424 N (6,189 to 7,739 lbf). [139] The extraordinary bite of crocodilians is a result of their anatomy.
The bite tears off the shark′s fin, helped by the classic death roll. Despite her injury, the shark is still strong. Then, the shark and the crocodile collide head on; the crocodile grabs hold of the shark′s snout with his crushing bite. This time, the shark cannot fight back; the crocodile attempts another death roll. After that, they both ...
Nile crocodiles are apex predators throughout their range. In the water, this species is an agile and rapid hunter relying on both movement and pressure sensors to catch any prey that presents itself inside or near the waterfront. [1] Out of the water, however, the Nile crocodile can only rely on its limbs, as it gallops on
The largest Nile crocodile accurately measured, shot near Mwanza, Tanzania, measured 6.45 m (21.2 ft) and weighed about 1,043–1,089 kg (2,300–2,400 lb). [1] Another large Nile crocodile specimen was purported to be a man-eater from Burundi named Gustave ; it was thought to have been more than 6.1 m (20 ft) long.
