Researchers studying a group of wedge-capped capuchin monkeys that live in tropical forests of central Venezuela have discovered that the monkeys protect themselves against the annual merciless onslaught of mosquitoes exactly as humans do: by rubbing themselves with mosquito repellent.

But while humans may reach desperately for spritzers or bottles or laughably overhyped ''protective'' skin-so-softeners, the capuchins have learned to poke around in tree bark or termite mounds to extract a wriggling specimen of Orthoporus dorsovittatus, a millipede rich with powerful defensive chemicals called benzoquinones.

The capuchin monkey will then proceed to anoint itself head to foot with the repellent secretions by massaging the four-inch-long millipe ...

Elephants really do get the point. New research has revealed that African elephants can spontaneously understand the intent of human pointing, and can use it as a cue to find food. While humans understand pointing from a very early age, only a few animals, such as dogs and horses, have the same ability, and it's thought that an elephant's understanding of pointing relates to the way they use their trunks to make gestures to each other in the wild.

While we're talking about Halloween, this is the Atlantic wolffish (Anarhichas lupus), very appropriately and otherwise known as the ‘devil fish’. The hefty fish grows up to 1.5 metres long and over 20kg, and they’re named for those unmistakable fangs. If they're not scary enough, their throats are also lined with a spattering of small, serrated teeth.

This two headed albino milk snake was born two years ago in Florida.

The condition is known as Polycephaly and occurs when monozygotic twins fail to separate completely. Most organisms with this condition will not live for long, but occasionally you will get cases like this one, where the snake(s?) seem healthy enough and can live for years.

The heads act independently of one another, and will fight over food given the opportunity. ...

This is the Grand Prismatic Spring in Yellowstone National Park - the largest hot spring in North America and the third largest in the world. The incredible colours are produced by pigmented bacteria that grow in microbial mats around the edges of the mineral-rich water. In summer, the mats are usually orange and red, and in winter they're are usually dark green.

This is the Giant Leopard Moth, a strictly nocturnal species native to parts of North America and Mexico. These moths start life as an incredibly black and bristly caterpillar, and once they grow into adulthood, they never eat, and instead focus on mating and passing their genes onto several clutches of eggs. ...

Researchers have found that Oreos are as addictive as cocaine, at least for lab rats. According to the new study, eating the black and white cookies activated more neurons in the rat brain’s pleasure centre than drugs such as cocaine.
