The Bushveld rain frog is found in Southern Africa. When threatened, it puffs itself up to ward off potential attackers.

The frogs are sexually dimorphic, and the male is too small to mount the female properly to reproduce. The white secretion you see on the back of the frog is actually an adhesive that holds the male in place during copulation.

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 ...

Check out this beautiful flower. At first glance, it looks like a set of lips, but in actually, these are the flowers that are produced by Psychotria elata, a plant that grows in Central and South American tropical forests.

The Banded Piglet squid is proof that not all deep sea creatures are nightmare-inducing. They swim "upside down" compared to other squid, leaving him resembling a Muppet with his tentacles as the hair, the syphon as the nose, and his patterning appearing to be a smile.

These guys live at least 100 m below the surface. Because of those incredible depths, it has to create its own light from the photophores underneath its eyes. Unfortunately, because it lives so far down, not much is known about its life cycle or eating habits. ...

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.

Engineers are building special drones that will deliver food to your table – or home. Besides the iTray, which brings customers sushi at a Japanese restaurant in London (above), researchers have developed a 'tacocopter' and 'pizzacopter' that can traverse six kilometers in ten minutes. But don’t get your hopes up yet, there are plenty of technological barriers to overcome before drones deliver pizzas to our homes.

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.
