Interesting facts
Neck vertebrae are the bones that make up the neck.
A
giraffe has a very long neck made up of seven vertebrae. You have seven vertebrae that make up your neck, too.
But it's a different story for birds. A bird has many more bones in its neck than you do – from 11 to 25 vertebrae. Slide6
Interesting facts
Great blue herons have been known to choke to death by swallowing fish too large for their long s-shaped necks.
Barred owls
swallow small prey whole and large prey in pieces, eating the head first and then the body.
