Why do giraffes have long necks?
Why do elephants have big ears?
Now, this next photo may make you squirm, but it leads in to the next question - in a way.
Is wombat poo really square?
Is there an animal with only one eye?
Why do zebras have stripes?
Do spiders have a heart?
Do fish have eyelids?
Why can't hens fly?
....and don't tell us this hen got up there with the help of the sheep.
