E1-04-Extreme Survivors 极限生存

Luckily, a Tyrannosaurus rex on the hunt is guided by some of the keenest senses in the Cretaceous.

Its eyesight would actually have been very, very good.

The eyes of a T. Rex are huge, the size of cricketballs.

A large retina collects more light, more visual information.

So, they can clearly see prey from as far away as 6 kilometers.

Critically, both eyes face forwards, and their line of sight overlaps.

So each eye looks at the same object from a slightly different angle.

That means T. Rex can experience the world in 3D.

There's very little in the environment of T. Rex that would escape its attention.

For the T. Rex hungry after months of growing her eggs, making a kill may mean the difference between life and death.
