Norway Coastline

Norway's coastline is long enough to circle the planet two and a half times.

Blue whale

A blue whale's tongue can weigh as much as an elephant.

Octopus

Octopus skin can change colour 177 times in an hour.

Dead Sea

All oceans and seas have salty water. The saltiest of all is the Dead sea. It is called "Dead Sea " Because the high salinity prevents any fish or other visible aquatic organisms to live in its water. Imagine 300 grams of salt in one liter of water. Interestingly, even if a person does not know how to swim, he would not drown in this sea. He would only float in it.
