Most mammals take 21 seconds to pee, regardless of their size
|
view preview
An elephant takes the same amount of time to empty its huge bladder as a cat - despite holding 3,600 times more urine. That's a whole lot of pressure. The controlling factor of urination duration is the length of the urethra, which gets longer at a predictable ratio as an animal gets bigger. All animals have urethras of the same aspect ratio: a length-to-width ratio of 18. This is rare among animals. Usually, body parts change in relative size, such as the eyes and brain. As the urethra gets longer, the effects of gravity increase and there's more pressure pushing out the urine.

Some animals prefer to marry their cousins

If you find yourself looking around the table over the holiday and thinking, “I can’t believe I’m related to these people,” just be glad you’re not a mongoose. If you were, you might be thinking, “I can’t believe I’ve mated with all of these people.” Why? For mongooses, it's actually safer to have sex with a close relative than risk death by venturing out into the world to find a mate.

Walking sushi

view preview
While this may look like sushi, it's actually Argentina's pink fairy armadillo. This rarely seen animal has silky white hair and a pinkish carapace; it ranges in size from 3.3 to 4.6 inches (84 to 117 millimeters) long, making it one of the smallest species of armadillos. The animal is also nocturnal and has the ability to bury itself in lightning speed given its long claws, which are an astonishing one-sixth the length of the body. ...

Tails designed to fool
|
view preview
The green wings of luna moths, with their elegant, long tails, aren't just about style. New research finds they also help save the insects from becoming bat snacks by creating a distracting acoustic signal, which causes these predators to zero in on the wings rather than more vital body parts.

A zoo where people are caged and animals roam free!

Ever seen a black flamingo?
|
view preview
On the Mediterranean island of Cyprus, you might be lucky to find a black flamingo. Normal flamingoes are born white and grey, and turn their iconic shade of pinky orange around the age of two, as a result of the high carotenoid content of the algae and crustaceans that they eat. Experts believe that this individual (and potentially the other bird spotted in Israel) has a genetic condition that causes it to overproduce melanin, changing its feathers to black.

Humans and Earth - the battle
|
view preview
When you turn on your TV, it is the definition of ironic to watch the news channels for information about planet mass destruction. Whilst when you step outside your door, it is quite alarming and obvious that our earth is suffering. When every person around you, from toddlers to elderly, own some for of technology, with no means of recycling old items. When students, each with their own copies of pages. When potable water has not yet reached the most needy of nations. When human greed is apparent with every innovative idea claiming to "revolutionize "a domain brought up to make a quick buck. Drilling, mining, industrialization, politics, scavenging for resources, suffocating our environment... This may all seem negative, but coming from a ...
