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.

[137] [138] 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). [138] The extraordinary bite of crocodilians is a result of their anatomy.
Bite force quotient (BFQ) is a numerical value commonly used to represent the bite force of an animal, while also taking factors like the animal's size into account. The BFQ is calculated as the regression of the quotient of an animal's bite force in newtons divided by its body mass in kilograms. [ 1 ]
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 ...
A 3.2-metre (10 ft 6 in), 164-kilogram (362 lb) specimen had a bite force of 4,355 N (979 lb f). [28] Its eyes have nictitating membranes for protection, along with lacrimal glands, which produce tears. The nostrils, eyes, and ears are situated on the top of its head, so the rest of the body can be concealed underwater for surprise attacks. [26]
Deinosuchus ( / ˌdaɪnəˈsjuːkəs /) is an extinct genus of alligatoroid crocodilian, related to modern alligators and caimans, that lived 82 to 73 million years ago (Ma), during the late Cretaceous period. The name translates as "terrible crocodile" and is derived from the Greek deinos (δεινός), "terrible", and soukhos (σοῦχος ...
False gharial. The false gharial ( Tomistoma schlegelii ), also known by the names Malayan gharial, Sunda gharial and tomistoma, is a freshwater crocodilian of the family Gavialidae native to Peninsular Malaysia, Borneo, Sumatra and Java. It is listed as Endangered on the IUCN Red List, as the global population is estimated at around 2,500 to ...
These crocodiles have dark-brown markings, which present as more pronounced bands in younger specimens and as scattered markings on mature ones. [7] One individual measuring 3.4 m (11 ft 2 in) and weighing 182 kg (401 lb) had a bite force of 6,276 N (1,411 lb f). [8]
