The angry-looking deep sea angler fish has a right to be cranky. It is quite possibly the ugliest animal on the planet, and it lives in what is easily Earth's most inhospitable habitat: the lonely, lightless bottom of the sea.

There are more than 200 species of anglerfish, most of which live in the murky depths of the Atlantic and Antarctic oceans, up to a mile below the surface, although some live in shallow, tropical environments. Generally dark gray to dark brown in color, they have huge heads and enormous crescent-shaped mouths filled with sharp, translucent teeth. Some angler fish can be quite large, reaching 3.3 feet (1 meter) in length. Most however are significantly smaller, often less than a foot.

Their mouths are so big and their bo ...

This 20-year-old male chimp suffering with alopecia, is a star attraction at an Indian zoo, as he sort of resembles a human. Perhaps being locked up in a zoo makes life a deeply distressing experience

The program builds on previous research and uses a mathematical model to determine which letter the test subject was thinking about at the time of the scan. Researchers hope to refine this technology in the future in order to reconstruct memories or dreams.

Take a good look at this woman. She was created by a computer from a mix of several races. What you see is a remarkable preview of what the North American race will look like.

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 Bonsai tree was planted in 1626, and survived the atomic bomb at Hiroshima on August 6th, 1945, 68 years ago today. It was given to the people of the United States as a Bicentennial Gift in 1976.

This photo shows a diver almost being eaten by a whale shark, the world's largest fish species. Marine photographer Mauricio Handler captured the intense moment during a dive in Isla Mujeres, Mexico, when more than 600 of the 12-metre-long animals gathered to feed on tuna spawn.
