They said on Dirty Jobs that the alligator turtle has the 2nd strongest bite in the world, but what has the strongest bite?
Ali gators and Crocodiles have a very strong bite, so do Hippos. But is it one of those animals or is there something with a stronger bite?
Answer
GREAT white sharks really do have the meanest jaws on the planet, say experts.
The fierce ocean predators have a bite force of about 1.8 tonnes - that's 20 times more powerful than humans.
Even a large African lion, with a bite force of 560g, can't compare with the shark's massive mouth.
Scientists used the latest X-ray and scanner technology for their research.
The team at the University of New South Wales made 3D models of the skull of an 8ft male great white using images from a CT scanner.
They digitally "crash tested" their computer model to simulate different scenarios and reveal the powerful bite of the fearsome predator.
The experts also worked out the complex distributions of stresses and strains that these forces impose on the shark's jaws.
But even the great white seems small fry when compared with the carcharodon megalodon. Dubbed Big Tooth, it was a prehistoric shark that was 53ft long and had a bite of around 18 tonnes.
It hunted large whales by biting off their tail and flippers before feeding at will.
By comparison, T-Rex could only manage a bite force of around 3.1 tonnes.
Steve Wroe, the study's lead author, said: "Pound for pound, the great white's bite is not particularly impressive but the sheer size of the animal means that it tops the scales.
"It must also be remembered that its extremely sharp serrated teeth require relatively little force to drive them through thick skin, fat and muscle.
"Nature has endowed this carnivore with more than enough bite force to kill and eat large and potentially dangerous prey."
Great whites can grow to about 20 feet in length and live for 30-40 years.
Hope it helps you!

Why canât biometric identification be used to make purchases online?
Emma
Biometric identification is basically face recognition, eye scanner or fingerprints which could be used instead of passwords and user names etc
I don't know if the answer is that you can't buy the technology yet to actually do that from home or because your fingerprint etc hasn't been linked up to your bank details or whether it's something blatantly obvious that i have missed.
Thank you for your help

I have recently gone across this great time and attendance device called SmartXS which scans on multiple levels and is really fast. They provide software support through which it can be customized and used for various applications. Even several banks have been using fingerprint scanners for the identification instead of writing PIN codes in their ATM machines. Face recognition will definitely take it to another level as this device scans dual retina and 3d face in less than a second. The company is Solotech Corp and its design is good too. Hope it helps.
