Fascinating Facts to Expand Your General Knowledge

 

While doing research for our latest short documentary I came across some intriguing facts I wanted to share with you:

 

Fact 1:

Fact 2:

Humans get the hiccups because we evolved from fish!

Mammal, bird, amphibian or fish… as an embryo we all look alike.

According to a BBC article the explanation is the following:

"A hiccup is caused by a spasm of the diaphragm, a big muscle in the chest, followed by an involuntary gulp. Both these actions have watery roots.

In fish the nerves that activate breathing take a short journey from an ancient part of the brain, the brain stem, to the throat and gills. In us, it is more complicated.

To breathe properly, our brain stem has to send messages not just to the throat, but down to the chest and diaphragm. This complex arrangement means that the nerves are prone to spasm, which can initiate hiccups."

Fact 3:

Hammerheads are the youngest of all shark species!

They came into existence some 20 million years ago while most modern day shark species are some 100 million years old! Hammerheads probably have the best senses of all shark species thanks to the weird shape of their head.

Fact 4:

There is a fish without a face and it lives in the deep!

There is a worm that looks like a penis, which is called the peanut worm.

These and more wonderfully strange creatures have been (re)discovered by a team of scientists on a recent marine expedition.
