Garden in a bottle
|
view preview
This miniature ecosystem has been thriving in an almost completely isolated state for more than forty years. It has been watered just once in that time. The original single spiderwort plant has grown and multiplied, putting out seedlings. As it has access to light, it continues to photosynthesize. The water builds up on the inside of the bottle and then rains back down on the plants in a miniature version of the water cycle. As leaves die, they fall off and rot at the bottom producing the carbon dioxide and nutrients required for more plants to grow. ...

The versatility of trees
|
view preview
How this bicycle got up in the tree has been the subject of plenty of local legend around Washington’s Vashon Island. The real story involves a boy in the 1950s who left his bike in the woods while playing with friends, because he didn’t like it. The bike was placed about two meters high in the tree, which eventually grew around it.

A monster of an ant
|
view preview
The bullet ant, or Paraponera clavata, lives throughout Central and South America. What makes this ant a formidable insect are its large mandibles and stinger. The bullet ant is one of the largest ants, growing to a length of just under 1 inch. Most notable about the ant is its ability to produce an excruciating sting.

The bleeding tooth fungus
|
view preview
The bleeding tooth fungus grows in Europe and North America. While young, the fungus looks like it is oozing blood. The red liquid is actually an anticoagulant. It lives on the roots of conifer trees and exchanges nutrients in a mutually beneficial relationship. And, if you're wondering, they are inedible.

Colorful trees
|
view preview
These are rainbow eucalyptus trees ( Eucalyptus deglupta) and they hail from the Philippine Islands. The trees get their name from the striking colours observed on their trunks and limbs. Although it may look like someone took a paintbrush to them, these colours are entirely natural. Unlike most trees, the rainbow eucalyptus does not have a thick, cork-like layer of bark on its trunk. The bark is smooth and as it grows it 'exfoliates' layers of spent tissue. This exfoliation technique occurs at different stages and in different zones of the tree. Once a layer is shed, a new fresh green bark is exposed. As this new bark ages, we can see the tissue change colour to dark green followed by a bluish colour, then to purple and pink-orange and then f ...

This is not an optical illusion
|
view preview
See anything peculiar? If you look closely, you'll see an Eastern screech owl hiding in plain sight. These owls are nocturnal and their amazing camouflage allows them to go largely unnoticed in the daytime. These owls only grow to about 22 cm (8.5 in) tall and weigh about 244 grams (8.6 oz), but they have been observed hunting squirrels and rats who rival them in length and weight. Eastern screech owls are found in North America from Canada all the way down to Mexico. ...

How to withstand a piranha attack
|
view preview
The arapaima ( Arapaima gigas) is one of the biggest freshwater fish on the planet and has evolved a multi-layer defence against the piranha. Its scales have an ultra-tough outer shell, which promotes tooth fracture at the point of penetration. The scales are also a corrugated shape, which deflect pressure to overlapping layers of collagen underneath.

A parrot with a wicked hairstyle
|
view preview
This is a Palm Cockatoo, also know as the Goliath Cockatoo. Palms are distinguished by their size, huge beak (second only to the Hyacinth Macaw among psittacines and largest proportionate to size), solid black feather coloration, large open crest, bare red cheeks, and red and black tongue. You have to see their tongues to believe the coloration. It's amazing. Palm Cockatoos are severely threatened. They are CITES Appendix I birds and are protected in Australia. As a testament to their rarity, typical prices in the U.S. for Aterrimus Palms are around $8000 and Goliaths around $14,000. Perhaps contributing to their rarity is the fact that, according to both Low and Forshaw, they lay only one egg per clutch. ...

Walking leaves

view preview
This stunning creature is the Amazonian leaf-footed bug ( Diactor bilenatus), a species that can be found throughout South American, in parts of Central America and on some Caribbean Islands. Although they look beautiful, when threatened the insect releases a bitter, unpleasant odour to scare of potential predators.
