Top ten most outsized animals in the world

10 OUTSIZED ANIMALS

Largest mammal (and largest animal ever) 

blue whale
Balaenoptera musculus
30m, 170 tonnes Larger than any prehistoric giant, the blue whale would dwarf the largest known dinosaur, Argentinosaurus, which weighed a ‘mere’ 80 tonnes or so.

Largest land mammal

African elephant Loxodonta africana 7.5m, 6 tonnes

Largest reptile

saltwater crocodile Crocodylus porosus  

6.7m, 2 tonnes


Largest snake

green anaconda eunectes murinus 

6.6m, 70kg


Largest dinosaur

Argentinosaurus
estimated to be 30-35m long, 80-100 tonnes

Largest bird

ostrich struthio camelus
2.1-2.8m, 145kg

Largest insect

goliath beetle Goliathus
spp. 60-110mm, 100g

Largest fish 

Whale shark Rhincodon typus 
12.65m, 21.5 tonnes


Largest amphibian

Chinese giant salamander andrias davidianus 2m, 30kg

Largest carnivore 

southern elephant seal Mirounga leonina 3m, 4 tonnes

HOW DO STARS DIE?

Stars die because they exhaust their nuclear fuel. The events at the end of a star’s life depend on its mass. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a ‘supernova’. What’s left over after a supernova explosion is a ‘neutron star’ – the collapsed core of the star – or, if there’s sufficient mass, a black hole. Average-sized stars (up to about 1.4 times the mass of the Sun) will die less dramatically. As their hydrogen is used up, they swell to become red giants, fusing helium in their cores, before shedding their outer layers, often forming a ‘planetary nebula’. The star’s core remains as a ‘white dwarf’, which cools off over billions of years. The tiniest stars, known as ‘red dwarfs’, burn their nuclear fuel so slowly that they might live to be 100 billion years old – much older than the current age of the Universe....

Why do different countries use different mains voltages?

Why do different countries use different mains voltages? the biggest disparity is between the usA on 110V and most of the rest of the world on 230V. America’s lower voltage goes all the way back to thomas edison, who introduced direct current (dC) mains electricity at 110V. edison’s rival nikola tesla showed that long power lines transmitted alternating current (AC) more efficiently than dC. His AC approach won out, but he stuck with edison’s 110V. But by the time electrification spread to europe early in the 20th Century, lamps had filaments that could give out more light and handle greater power loads. so the Berliner elektrizitätswerke company in Germany established 230V as the standard.

DOES HOLDING YOUR BREATH MAKE YOU STRONGER?

It won’t make you stronger in the sense of building muscle in your heart or diaphragm, but holding your breath while training for certain sports has been shown to improve the ability of your muscles to cope with short, intense exertions. This works by increasing the concentration of bicarbonate in the blood, which helps to neutralise the lactic acid produced during anaerobic exercise. For this technique to work, you need to exhale normally and hold your breath when your lungs are empty, rather than taking a big breath in and holding that. There are significant risks, though. A 2009 study found that free divers who regularly held their breath for several minutes had elevated levels of a protein called S100B in their blood, which is an indication of long-term brain damage.
