Crocodiles seem to spend their entire lives with every sense turned towards the hunt.
On a river bank in East Africa, crocs are hatching.
The gender of each is determined by the heat in the nest.
If the egg stays between 88 and 90 degrees, it produces a male.
Higher or lower and it produces a female.
Now they're vulnerable.
A quick snack for hungry predators.
But this is their mother...and she's not eating them...she's protecting them.
To gently pick up her babies, she uses the deadliest jaws on the planet.
They're capable of delivering a bite force of 5,000 pounds per square inch, which makes them more than seven times more powerful than a great white shark's bite.
This mother carries a mouthful to safer waters.
Even then, she has to stand guard.
Only one percent of newborns make it to adulthood.
This youngster's instinct to kill is there almost from day one.
As it grows bigger, it moves its way up the food chain.
Feathered, furred or otherwise, all that matters to the croc is that it's edible.
