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. ...

The Brazilian Jaboticaba tree well and truly takes advantage of all the surface area on its trunk by growing its sweet, grape-like fruits all over it. It's said to have evolved its trunk-fruit so animals could reach them and distribute the seeds.

We often hear people say that modern birds evolved from some dinosaurs. Apart from both being reptiles, what evidence have paleontologist discovered that validates this claim?

A small bird-like dinosaur, called the archaeopteryx (left), lived in what is now southern Germany about 150 million years ago. About the size of a crow, it had a shortened tail, long hands, a perching toe slightly turned backward, and wing feathers that were adapted for flight. This creature has long been considered the most ancient bird known. However, despite its birdlike characteristics, its body more closely resembled those of small meat-eating dinosaurs than those of more birdlike dinosaurs. Many paleontologists identify the archaeopteryx as the so-called missing ...

The Mandarin duck is a sexually dimorphic species, meaning males and females differ in appearance. The male has a rich, colorful appearance, which includes brown cheeks and a long brown and white crown sweeping back from the top of the head. The chest is dark purple, with black and white strips, and the wings are brown with an iridescent blue-green edge. This striking coloration helps the male attract the less-colorful females, which display brownish-black plumage with white markings around the eyes and along the throat. ...

This is the larva of the Hemeroplanes triptolemus moth. In its larval form it is capable of expanding its anterior body segments to give it the appearance of a snake, complete with simulated eyes. It's mimicry extends even to the point where it will harmlessly strike at potential predators.

While the video may look like a trick an owner could teach their animal to do, some birds actually do play dead to avoid predation. If they feel in danger, they will essentially 'play dead' since predators are more interested in live, healthy prey than dead prey.

It turns out that our evolutionary cousins can recall number placement better than people can. In the experiment, the task requires the chimp to touch the numbers in ascending order and he has only seconds to make his decisions. The numerals appeared only for a certain limited duration, and were then automatically replaced by white squares. After touching the number one, the rest of the numbers are obscured by squares, making the chimp reliant on his memory to correctly pick the numbers in the right order. After a whistle sounds, the numbers reappear in different positions, so the chimp has to remember the position of all nine numbers after seeing them only briefly. And the chimp quickly aces the test time and time again, r ...
