The giant squid once faced a population bottleneck
|
view preview
Genetic testing of giant squid corpses discovered all over the world has found that not only are they all the same species, they have surprisingly low genetic diversity. This suggests that some time in the recent past they were pushed to the brink of extinction, but managed to rebound and are now found throughout the worlds oceans.

The mammoth of birds
|
view preview
This bird, known as the elephant bird, went extinct sometime in the 17th century as a result of human activity. Although flightless, the birds were widespread, inhabiting the northern to the southern tip of Madagascar. Not only are they three times the size of an ostrich, they are also known for their massive egg. These fossils are so rare that one is currently being auctioned and is expecting to go for an upwards cost of $40 000..

One very massive, shell-less turtle
|
view preview
The Leatherback Sea Turtle is the largest turtle in the world, weighing approximately 900 kg. Contrary to appearance, the leatherback doesn't actually have a shell. What looks like a shell is in fact a leathery skin supported by small bones. This gives it a flexibility that a solid shell would not provide, allowing it to dive to astonishing depths.

Massive katydid
|
view preview
This Malaysian katydid is one of the largest insects in the world, with their bodies growing to 15 cm (6 inches) long with a 25 cm (10 inch) long wingspan. Though the last thing you want to hear is that this giant insect is carnivorous, they pose absolutely no threat to humans (aside from haunting your dreams, of course). Relatively speaking, the males of this species have the largest testes of any known animal at 14% of their body weight. If humans had the same ratio, a 91 kg (200 lb) man would have testes that weighed nearly 13 kgs (28 lbs)! ...

Here's what 83 times optical zoom can do
|
view preview
Watch the Nikon Coolpix p900 camera zoom into the moon. This is the first bridge camera on the market with an 83x optical zoom, and it sure is something. It also includes a digital zoom, which reaches to 166x, or 4,000 mm. What is the difference between optical and digital zoom?An optical zoom is a true zoom lens, like the zoom lens you’d use on a film camera. They produce much better-quality images. Some cameras offer a digital zoom, which is simply some in-camera image processing. When you use a digital zoom, the camera enlarges the image area at the center of the frame and trims away the outside edges of the picture. The result is the same as when you open an image in your photo-editing program, crop away the edges of the picture, and t ...
