Car-crushing bites

The largest saltwater crocodiles delivered a crushing 16,414N, more than 3.5 times that of the previous record-holder, the spotted hyena. The crocodile's bite was slightly weaker than that of the great white shark – but the shark's bite was only simulated.

At the other end of the scale, the diminutive South American fish known as piranhas have a reputation for biting sizeable chunks out of their prey. However, in a 2012 study, researchers measured the bite force of the black piranha to be 320N. That is feeble compared to the great white shark, even when you factor in the size difference.

I wonder what the pressure is though. I'd bet piranha teeth are smaller and sharper than crocodile teeth.

The whopping shark known as Carcharodon megalodon went extinct 2.6 million years ago. It may have grown to almost 66ft (20m) long, nearly 3.5 times the length of the biggest great white sharks. The shark bite researchers estimated the megashark's bite to be an "extraordinary" 108,514-182,201N. That is enough to crush a small car.

However, palaeontologists are divided as to whether it could leap high enough out of the water to catch a jumbo jet.
