FROG ▶
The skull of a frog is broad,
providing plenty of room for
its large eyes and giving it an
extremely wide mouth. This
allows it to swallow its prey
whole, so it does not need a
set of teeth for chewing.

◀ LION
Like all cats, the lion is a dedicated
hunter. It has short, powerful jaws with
huge stabbing canine teeth at the front,
and meat-slicing carnassials at the back.
CROCODILE ▲
One of the closest living relatives of
the dinosaurs, crocodiles have long
jaws studded with many sharp-pointed
teeth for seizing their prey. The fish-
eating gharial of Indian rivers may
have more than 100 teeth.

PARROT ▶
All birds have thin, light skulls, which
makes flying easier. Their beaks or
bills are much lighter than toothed
jaws. They are not built for chewing,
yet the bills of some parrots are
strong enough to crack nuts.
