Hippos have huge mouths to accommodate their large teeth and tusks.
Their teeth are used for fighting, not chewing.
Hippos are not efficient chewers because they have a simple stomach and short intestines.
Their diet consists mainly of grass, which is easy to digest.
Hippos have adapted to their environment by being able to go without food for long periods of time.
They also have the ability to store food in their stomachs for later digestion.
Despite their bad chewing ability, hippos are still able to maintain a healthy diet.
