Why big cats only roar not purr ??

 Big cats roar .....

Small cats   purr   !!!!

They can't do both  ........  !!!

WHY  ??

Its about their throat .....

Big cats like lions and tigers have a stretchy throat.

Stretchy throat lets them make a BIG loud ROAR  !!!

But it can't vibrate fast..... So they can't PURR ......

Small cats like house cats have a stiff throat.

This lets vibrate  faster making sound PURR ......

It can't make a big ROAR  !!!

Cheetahs are exception... 

Though they are one among big cats,  they can purr not roar

Because their throat is just like a small cat    ....!!!!

Question 

Which is the most populous country in southern hemisphere  ??

1.  Malaysia 

2. Canada 

3.  Nigeria 

4.  New Zealand 

Answer 

In the question they were asking about most populous country in southern hemisphere.

But in the options given, 3 countries Malaysia, Canada and Nigeria are from northern hemisphere  !!!

Only New Zealand lies in southern hemisphere......

But I doubt about New Zealand as the populous country.

I decided to cross check   !!!!

I asked with Artificial Intelligence.

It directly rejected the name of New Zealand !!!

It said New Zealand is very small.

Population is nearly 5.2 million only.

Most populous countries in southern hemisphere are   -----

Brazil  with 215 million population.

Indonesia with 280 million population.

New Zealand is not even in top 10  !!!!

Why round animals are rare on land ???

  I know millipedes curl themselves when they are threatened.

Armadillos and pangolins also go round only to protect themselves.  Then they will unroll to move  !!!

On land, animals need strong legs and long bodies to survive.

There are 3 reasons why round animals are rare on land  -----

1.  Round means rolling. But we can not control where we roll !!!

       Land animals require to run, climb, walk and dig.

       That's why land animals evolved legs instead of round bodies   !!!

2. Round shape has smallest surface area.

    It is best to keep heat inside.

     But land animals need to dump heat as they run.

    That's why land animals evolved legs instead of round bodies  !!!

3.  Round animals don't have limbs.

       They can not  reach or grab.

      Land animals need to move faster to escape from predators.

       That's why land animals evolved legs instead of round bodies  !!!
