Fact: Most Dangerous Animal In Africa ?

Apart from snakes and insects the hippopotamus kills more people in Africa than any other! It’s a statistic which many find shocking especially because they’re not actually meat eaters. So what makes the hippo so dangerous ?

Well to begin with they’re large, extremely bad tempered and surprisingly quick on both land and water. If you combine these factors with a strong set of jaws and large tusks you have an animal with an extremely destructive bite.

Most attacks seem to occur at watering holes or near to water where humans either come too close or simply disturb the hippo from a distance. So just remember next time you’re in Africa it’s not only the lions, cheetahs and crocidiles you need to worry about. Beware of the bad tempered hippo!

Fact: How Do Camels Survive The Desert ?

The body of a camel is so amazingly adapted to survival in the desert that it can with stand even the harshest of desert climates. Their biggest strength has to be their ability to survive without food and water for long periods of time. This unique ability stems from their body being able to store fat in their humps and water in the lining of their stomachs. These stores can be used in times of need which is ideal in deserts where both food and water are extremely scarce.

Their wide, padded feet grip well on loose sandy soil and stop the camel from sinking into the sand. An insulating wool coat keeps out both the heat of the day and the cold of the night. Hairy eyelashes, ears and slit nostrils keep out the desert dust and sand. If that wasn’t enough camels are also extremely simple about the food they eat, consuming anything from thorny shrubs to desert thistles.

Fact: Grizzly Bear Facts

Did you know that the grizzly bear (Ursus horribilis) can weigh up to 800lbs and reach heights of up to 8 foot when standing on its rear legs. With such mass and size you would expect it to be extremely slow but despite such size it can sprint at speeds as high as 40km/h which is faster than an olympic athlete.

In terms of behaviour and temperament the grizzly bear is a solitary animal sticking to itself except during mating season. Its reputation of being extremely aggresive is a little exaggerated as in most cases it won’t go out of its way to hunt humans or cause trouble. 

So why do people fear the grizzly so much ? Well much of its aggressive reputation stems from the fact that it can’t climb trees very well, which is what most bears do to avert danger. This ultimately means that a threatened grizzly is more likely to stand its ground and attack an oncoming threat rather than running and hiding. 

So despite the stories and the movies, the grizzly in most cases is unlikely to go on aggressive hunting sprees. More so they’re omnivores so will just as happily consume berries, fruits, pine nuts and roots.

Fact: Some Animals Just Don’t Need Males

Did you know that there are certain animal species where there are no males only females. This is fairly common among insects and worms but also occurs to a lesser extent in some lizards.  Due to only one sex existing the females are actually able to lay eggs without the need of a male (i.e. no fertilization is required). 

This method of reproduction is known as parthenogenesis and will almost always leads to the birth of female offspring.  As an example the New Mexico whiptail lizard is 100% parthenogenic and has been bred in captivity for many generations with no males at all.

Fact: Do Jelly Fish Have Bones ?

Did you know that all Jellyfish no matter how large or small have no solid skeleton to support their body. Instead their shape is maintained by soft water filled inner tissues, over which its outer layers are stretched. Take a jelly fish out of water and its beautiful shape and size is visible as nothing more than a primitive lump of jelly. 

Despite this lack of bone structure don’t be confused into thinking these creatures are helpless. These beautiful animals have actually been in existance for over 650 million years (making them outdate the Dinosaurs) and have always been extremely effective as predators.

The Box Jellyfish for example is the deadliest sea animal in the world killing more humans than even sharks, and what about the Lions Mane jellyfish which has a diameter of over 8 metres and tentacles as long as 60 meters (that’s over half the length of a football field).

Fact: The Oldest Living Thing On Earth

Trees live much longer than any other type of plant or animal. In fact it’s possible to know the age of a tree by counting the rings in its trunk (One ring generally equates to one year).

The oldest living tree and hence one of the oldest known living things on Earth is a bristlecone pine tree located in California, North America, it’s actually over 4600 years old, now thats old.

Fact: Fractional Distillation Of Air

Did you know that the air we breathe isn’t just oxygen, infact it’s made up of a number of different gases such as nitrogen, oxygen, carbon dioxide, argon, neon and many others. Each of these gases carry useful properties so separating them from the air around us is extremely beneficial. 

The process is called fractional distillation and consists of two steps, the first relies on cooling the air to a very low temperature (i.e. converting it into a liquid), the second involves heating it up thus allowing each gas within the mixture to evaporate at its own boiling point. The key to success here is that every element within air has its own unique boiling temperature. As long as we know these boiling temperatures we know when to collect each gas. 

So what are the real world benefits of separating and extracting these gases? Well liquid oxygen is used to power rockets, oxygen gas is used in breathing apparatus, nitrogen is used to make fertilizers, the nitric acid component of nitrogen is used in explosives.

The other gases all have their own uses too, for example argon is used to fill up the empty space in most light bulbs (thanks to its unreactive nature). Carbon dioxide is used in fire extinguishers and is great for putting out fires in burning liquids and electrical fires. There really are too many uses to list but suffice it to say that fractional distillation is an extremely useful process for humans the world over.
