Check out this amazing image of am urodid moth cocoon. According to entomologist and Amazon explorer Phil Torres, It has a really beautiful woven lattice structure that hangs about a foot below a leaf on a thin silk string.

This is an unusual structure because the pupa, resting inside the cocoon, seems fairly exposed to the elements. The hanging likely helps to prevent predation from ants, and the bright orange color may serve as an aposematic signal to predators to prevent it from getting eaten. The tube part at the bottom is the 'escape hatch' from which it eventually will exit as an adult moth. There is not a lot of research that has been done on the evolutionary origin structure - this is one of the many mysteries of the Amazon you can c ...

This photograph of a great white shark following a kayak is probably one of the most iconic and popular shark images of all time. Every time it pops up, it unsurprisingly garners a lot of accusations of being fake, or edited.

The Yellow Pages use no virgin paper in the production of their directories, but to produce and deliver 540 million a year requires immense amounts of water and uses immense amounts of energy and fuel. If you need the Yellow Pages, keep it! But if you are among the 70% polled who say they never even open them, opt out. It is just a waste not to.

Meet the goliath frog! This beast is the largest extant anuran on Earth.


They can grow up to 33 cm (13 inches) from snout to vent, and can weigh up to 3.2 kg. They have a fairly small habitat range, mainly in Cameroon and Equatorial Guinea and sadly their numbers are dwindling due to habitat destruction. They are also hunted for both consumption and for the pet trade.

Octopus reproduction is fairly uniform across species. When a female is ready to mate, she releases a chemical into the water that attracts males. They follow this chemical to the female, where they will often fight one another for the right to mate with the female. Sometimes the female will mate with more than one male. The same chemical that attracts the males stops the males from eating the female - cannibalism is common amongst octopodes.

Once it has been decided who will be mating, the male transfers packages of sperm called \"spermatophores\" to the female using his third right arm (which typically has no suckers). The female stores these, and then builds a den. She then seals the entrance. Once this is complete, she lays the eggs and ...
