The animal world is full of natural-born singers. Give it up for Mother Nature’s chart-toppers . . .

This isn’t just any old grasshopper. It’s called a Katydid, because the song it sings over and over sounds like ‘Katy did! Katy did!’

Maybe it’s trying to tell us something about Katy Perry, or maybe it’s just our imagination, but either way, this bug likes to sing in the evening. And instead of using its mouth, it just rubs its two front wings together.

On one wing is a row of teeth (like a serrated knife) and on the other is a hard edge called a scraper. When a male wants to sing, he rubs the scraper against the teeth and hey, presto! His song carries over the crowd of female fans.

Believe it or not, humans use a similar system to make music. A CD stores data in a long row of bumps, which are too small to see with the naked eye. These bumps are read by running a laser beam across them, just like a katydid’s scraper.

Ever wished you could imitate the school bell? well, this australian bird can. it can also copy chainsaws, fire alarms, barking dogs, the human voice and many other crazy sounds! a bird’s vocal organ is called the ‘syrinx’, and as far as syrixes go, the lyrebird has the Super deluxe model. it comes with the most complex muscular system of all songbirds,

giving it amazing musical skills. if this bird made it into

hollywood, it would put some people out of a job. when a movie is made, sound effects editors are hired to create all kinds of strange noises – people’s heads being chopped

off, alien spaceships landing and so on. and they often use

real animals to get the perfect sound – the roar of the t-Rex in

Jurassic Park, for example, was the sound of a baby elephant mixed with that of a tiger and an alligator! Bet the lyrebird can’t do that … Search ‘lyre’ at www.hip2b2.com to hear what it can do.

ScientiStS create a Singing mouSe!

a few months ago, Japanese scientists announced that they’d created a mouse that tweets like a bird. Seriously. the mouse

is part of an experiment called the ‘Evolved Mouse Project’, which was created to see how mice would change if they evolved a little faster. the researchers created a group of mice with dna that mutates – or

changes – more easily. when an animal’s dna changes, this can affect the way its babies look or behave … and that’s what causes a species to evolve.

the scientists didn’t plan to create a singing mouse, but a random change in one of the parent’s dna codes created a tiny, tweeting baby. and by looking at how other mice respond to the strange new sounds and how the sounds change in different situations, scientists hope to get new information about how language is created.

Smart tech: Boulder Cam wild animals aren’t used to

paparazzi, so it’s not easy to get close-up footage. which is why a British filmmaker named John downer created a remote-controlled camera that looked like a boulder. Because it didn’t freak

the animals out, the camera could be wheeled right inside a lion’s den, where it captured 3 000 hours of footage of the cubs growing up. imagine all the

other rare or shy animals we could learn more about with this technology! to watch a video, visit

they may not look like natural-born performers, but these monkeys love to sing. if you’re ever in

thailand, malaysia, singapore, Burma or southwest china, you might see these white-handed gibbons, also known

as lar gibbons, swinging around in the trees. the boys are black and the girls are beige, and if you see a

couple, listen out for the song they sing together. sitting at the top of a tree, they’re known to shout out their love for each other – opera-style – especially in the mornings or evenings. their ‘whoops’ and ‘whooahs’ also tell other

monkeys to stay away from their love nest. the female usually starts the performance with a sad call that

gets louder and louder. the male then joins in with high-pitched hoots. But these monkeys won’t be singing for long if we don’t stop destroying their forests. people also hunt them for meat and sometimes, parents are even killed so humans can sell

their babies as pets! to hear the song of the gibbons, search ‘monkey duet’ at

www.hip2b2.com.

It may only be about as long as your finger, but this sea creature has a deadly weapon: sound.

Found in the tropical Indo-Pacific ocean, the tiger pistol shrimp is the loudest animal on Earth. It can make a sound of up to 200 dB – louder than a rock concert (115dB) and 20 dB louder than our ears can handle … (For more info on decibels, turn to page 7.)

So how does it work? When a tiger pistol spots his prey, he aims his claw like a gun and snaps it shut, firing a blast of bubbles that can reach 5 500 ºC – as hot as the sun – as they burst. This stuns the prey and throws it onto its back. Search ‘shrimp’ at www.hip2b2.com to see it in action.

But tiger pistols aren’t the only creatures to use sound as a powerful weapon. Armies have been known to use explosives called stun grenades or flash-bangs, which disorientate the enemy by producing a loud bang and a blinding flash of light.

Confessions of Georgia Nicolson Reviewer: Kendal Pyle, Grade 10, Harvest Christian School, PE

In this series of books, we meet

14-year-old Georgia Nicolson,

whose irony and humour cover

everything from pedantic

parents to her bed-wetting little sister Libby.

Georgia records the events that happen almost

daily in her diary, creating a hilarious account of

her life. Through it, we learn what it means to be a

modern girl on the brink of womanhood.

Author Louise Rennison is a comedy

writer … and it shows. Whether Georgia

is dealing with wearing a bra, pondering

which way to turn your head when

kissing, or managing the results of an

overzealous eyebrow-plucking episode,

she always cracks me up. Rating: 5/5

We catch up with the singers behind that catchy song called ‘Lovesick’.

MegaMind Reviewer: Jasmyn Connor, Grade 11, Danville Park Girls’ High School, DurbanMany animated films have received positive reviews, but this one goes beyond the rest.

MegaMind is an alien criminal who overcomes his extra-terrestrial nemesis, MetroMan, only to discover that total oppressive domination isn’t all he thought it would be. He creates a hero to try to get life in MetroCity back to normal, but his plan backfires, leaving him to question whether he really is meant to be evil at all.

ANSWERS

Where does your name come from?

One night, Pam had a dream that she

was on an arrow, being shot over forests

and oceans. It was vivid and powerful.

The next day at rehearsal Christie, out

of the blue, said: ‘I think we should call

ourselves The Arrows.’ And that was that.

Why is your album called Make Believe?

It’s about making your dreams become

reality. The title has a lot of meaning

for us, as an independent band that isn’t

signed to a record label. Getting our music

to reach audiences around the world is a

dream that we’ve had to make happen.

What were your favourite school subjects?

Pam: Drama and Home Economics.

Christie: Science

The Arrows: Christie Desfontaine (left) & Pam de Menezes (right)
