Giving birth to a child is not an easy feat.

Just ask my mom.

But humans have things pretty easy compared to the utterly bizarre birthing practices of certain creatures on our planet.

From snails with very unfortunate anatomies to rodents born covered in sharp spines,

here are some of the most incredible and crazy ways animals give birth.

You're listening. You're listening to be amazed.

New Zealand's Kiwi bird is not like most other birds. It's completely flightless,

it burrows underground and takes almost 30 days to produce an egg. But not just any egg. The

Kiwi is known to lay the biggest egg in proportion to its body of any bird on earth. These

things don't mess around. A single egg can take up as much as 25% of the mother's body mass.

That would be like an average human mother giving birth to a four-year-old toddler.

The Kiwi mother's organs become so compressed during this time that she's often unable to feed in the final few days of her pregnancy.

But once laid, the Kiwi chick has a competitive edge in this scary new world because

it's already well developed. Once the chick hatches, it's almost fully formed. Scientists theorize

that the chick develops in this way so that it has the ability to run and evade predators

soon after birth. Though I can't imagine running from a predator would be a very nice way to enter the world.

Still, to be born a flightless bird, I guess you have to hit the ground running.

It's not just size that can make birth difficult for animals.

Take the porcupine, for example.

These giant rodents are famous for the sharp quills that cover their bodies and for a good reason.

With each spike containing up to 800 tiny barbs along the

tip, they're incredibly painful and hard to remove. But while they're effective at keeping predators
