It has been reported that at least one snail lived as many as 14 years in captivity. His name was George and he lived in Hawaii, in the United States.
Yolks are a great source of vitamins, minerals, fats and proteins packaged up by the female animal for an embryo.

A yolk allows a developing animal to stay in an egg longer, boosting its chance of survival. The downside is the mother has to work hard finding extra food so her body can create a nutritious yolk.
What’s left after a star explodes.

By studying old and dead stars, we can discover what will happen to our sun in the far, far future. And it won’t end with a big explosion.
The sea is blue because of the way water absorbs light, the way particles in the water scatter light, and also because some of the blue light from the sky is reflected.

Photons stream from the sun and interact with all matter on Earth. Depending on what the light touches, some of the photons will get absorbed or soaked up. And some will bounce back.
Whiskers are not just ordinary hairs. They are thicker and go deeper into the tiger’s skin and send messages to its brain about what is happening in the world around it.
When a sound is made, it spreads. And when it hits a hard surface that is far away, it bounces back and comes back to where the sound was made. That’s what we call an echo.
Right now, your kidneys are getting rid of all things your body does not need. They do this by ‘cleaning’ your blood.

It’s good to know how currents are formed in the ocean, as they can be quite dangerous!
A headache is not from your brain itself hurting, but it might mean some of the muscles, membranes and tissues surrounding the brain or its blood supply system could be hurting.

The brain itself can’t actually feel pain. It can’t sense damage to itself the way your finger can. We know this because people can have brain surgery while they are totally awake.
Fruit ripening is all about plants getting animals to eat the seeds that are inside their fruits. This helps the plants get their seeds to somewhere new where they can grow into a new plant.

An adult brain weighs about 1.5kg. It’s mostly water with some fat, protein, sugar and a dash of salt. Sounds like pancakes, I know, but I once tried chicken brains and, well, pancakes are tastier.
A few days after baby molluscs come out from tiny eggs, they start building their shell layer after layer.
Emily Nunnell/The Conversation NY-BD-CC
Molluscs that have shells - like pipis, clams and oysters - have to build their own shell from scratch. And they keep building it their whole life, using chemicals from the sea and their own bodies.
The pressure in the deepest part of the ocean can be 1,000 times greater than the pressure we experience at sea level – but creatures that live and visit there have some very special features.
Some people think the mummies brought good luck!

Your stomach works very hard with some other body parts to break down food into small pieces. Your body takes in what it needs and the rest is turned into poo.
