– [Narrator] How is it doing that?
Hamsters, like Soda Pump,
can stuff up to 20% of their body weight into their cheeks.
For comparison, that’s like the average person
carrying around 30 extra pounds of food, or about 120 quarter pounders.
It would be a cool party trick,
但是不太舒服 或者让我们面对现实吧 不可能
but not very comfortable or, let’s face it, even possible.
That’s where hamsters are different.
But they don’t stuff their faces for parties,
or even because they’re hungry.
They do it to survive.
HOW HAMSTERS CAN STUFF SO MUCH FOOD IN THEIR CHEEKS?
In the wild, yes, there are actually wild hamsters,
They eat all kinds of food,
树叶 嫩枝 蔬菜 和水果
leaves, shoots, veggies, and fruit.
What they don’t consume right away,
they store in those cheeks, which have pouches
that extend half way down their body
and expand like a balloon.
Thank goodness we don’t have anything like that,
because it would probably look a little strange.
But hamsters need to stuff their faces
no matter how goofy it might look.
In fact, they have to eat around every two hours
to function normally, butforaging for food this frequently
would make them easy prey.
Instead, they collect food at night,
and what they don’t store, they snack on along the way.
So during the day they can hide from predators
and munch on their hoard in safety.
And thanks to the pouches in their cheeks,
that stockpile can get enormous.
Hamster burrows have been foundwith nearly 200 pounds of stored food.
These cheeks also come with special retractor muscles
that help the hamster stuff itself to maximum capacity.
If you ever watch this in action,
you may notice that it reorients the food after plopping it in its mouth.
What it’s actually doing is angling the food
so it easily slips to the back of the pouch as more comes in.
Once the food is well on its way,
that’s when the retractor muscles come into play.
When the pouch stretches, the muscles contract,
which pushes the food toward the back,
preventing it from clogging up.
Pretty impressive stuff.
But that’s not as impressive as some of the other things
hamsters can do with their cheeks.
For starters, some specieswill hide their babies
inside these pouches to keep them safe.
There are reports that otherscan inflate their pouches
with air and use it as aflotation device for swimming.
But don’t try this at home.
Only certain wild species do this,
and we don’t want you todrown your poor hamster.
We’d rather have you sit and enjoy the incredible cuteness of Soda Pump.
Here’s a fun fact.
Hamsters can run over fivemiles in a 24-hour period.
