The Planet Earth - Beauty of the Blue Planet

Little Crater Lake

The lake is oligotrophic, meaning that there is nothing living in that lake. Combine that with water being blue in large volumes like this (yes, water is actually the color blue) and you have yourself an unpolluted, crystal-clear blue lake with visibility straight to the bottom in most cases. Whenever a lake doesn't look like this, it's probably due to it being able to host life, also known as an "eutrophic" lake.

Carolina Parakeet

These creatures are now extinct. They used to fly in groups and if someone shot one of them down, they would come down to check on it and increase the chances of them getting shot at again.

Golden Tortoise Beetle

Golden Tortoise Beetle: Insects commonly known as "goldbugs" sometimes attract the attention of gardeners when they feed on plants in the family Convolvulaceae. Although these insects are occasionally abundant enough to cause serious levels of defoliation, they are mostly a curiosity.

Elephants Migrating Through a Thailand Forest River

An X-ray of an elephant’s foot will reveal that its bones are actually standing on tip-toe. Their feet are flat because of a large pad of gristle under each heel which acts as a shock absorber and helps them walk quietly. Their legs are much straighter than those of other animals and support their weight so well that elephants sleep while standing. Elephants spend most of their lives walking huge distances, and their feet are suitably adapted to such a lifestyle.

Rainbow Eucalyptus (deglupta) Tree

Rainbow Eucalyptus Tree - Photo taken at Maui, Hawaii
The unique multi-hued bark is the most distinctive feature of the tree. Patches of outer bark are shed annually at different times, showing a bright green inner bark. This then darkens and matures to give blue, purple, orange and then maroon tones.
