Crocodiles have strongest bite of any living animal.
For the study, researchers led by Gregory M. Erickson of Florida State University Florida State University, at Tallahassee; coeducational; chartered 1851, opened 1857. Present name was adopted in 1947. Special research facilities include those in nuclear science and oceanography. , measured the bite forces, as well as tooth pressures, for mature adults from all 23 living crocodilian species, including crocodiles, alligators, caimans, and gharials.
The strongest biter was a saltwater crocodile The Saltwater or Estuarine Crocodile (Crocodylus porosus) is the largest of all living reptiles. It is found in suitable habitat throughout Southeast Asia and northern Australia. Saltwater crocodiles are known in the Northern Territory of Australia as 'salties'. at 3,700 pounds. It also generated record setting pressures exceeding 360,000 pounds per square inch Noun 1. pounds per square inch - a unit of pressure
pressure unit - a unit measuring force per unit area .
"Our study has allowed for a comprehensive understanding of the relationships between the anatomy, biomechanics, performance, and ecology among living and fossil crocodilians from which the secrets to their 85 million year success can be gleaned. Notably, the largest extinct crocodilians generated bite forces in excess of 23,000 pounds, values two-fold greater than T. rex," they said.
The researchers found that bite force was correlated with body size, but showed surprisingly little correlation with tooth form, diet, jaw shape or jaw strength.
Their results suggest that once crocodilians evolved their remarkable capacity for force-generation, further adaptive modifications involved changes in body size and the dentition dentition, kind, number, and arrangement of the teeth of humans and other animals. During the course of evolution, teeth were derived from bony body scales similar to the placoid scales on the skin of modern sharks. to modify forces and pressures for different diets.
The finding has just been published in the open access journal PLoS ONE. ( ANI )
