I really enjoyed this book as I loved the storyline! I love how she makes you feel like you are Ella! I would recommend it to anyone!" Whales are social on a scale that is difficult for the human eye to perceive. Whales in southeast Alaska will maintain relationships for decade. They'll get together every year in similar locations to forage together ." How can whales actually sing? To the best of our knowledge, whales make sound by moving air between various sinus cavities in their skull and across something called ‘phonic lips’ or ‘vocal folds’. In this way, it’s not that different from us,” says Fournet. As well as winning many awards for her books, including the Children’s Book of the Year, Jacqueline is a former Children’s Laureate, and in 2008 she was appointed a Dame. We began our study by trying to figure out why such a small animal with such a small head could locate fish very far away – this ability could not be explained by textbooks,” he says. “They use muscles to physically deform their heads to change the angle of the beam – this was not known at the time. But we still don’t’ understand how exactly they receive the signals. I also want to understand how they form clear images.

Ella - A lonely young 8-year-old girl, who is worried out of her mind for the safety of her mother. Her favorite animal becomes the whale as she studies about them to try and bring her mother out of the coma. She hates her stepfather and blames him for everything. Her real father comes to visit her out of the blues and he buys her a guinea-pig.While apes are renowned for their colour vision, and humans like to think of themselves as visual creatures, cetaceans have no use for expensive ocular equipment. Instead, they have evolved some of the most distinct, complex and unique acoustic anatomy and behaviour on earth. Cetaceans see and feel with sound. You can see how echolocation would evolve if you’re in a dark environment like a cave or the deep ocean – there are in fact many blind humans who have learned how to echolocate, and even normal sighted people can tell if they are in a huge chamber or a crowded room just by listening to the acoustics,” he says. “But while bats have a typical mammalian ear, cetaceans have a much more specialised system.” Evolving for sound I haven't read The Longest Whale Song yet but I love all of Jacqueline Wilson's books and I'd like to read it!" So it is no surprise the military realised they could learn a thing or two from dolphins about how to use sound underwater. Military scientists in four countries – the US, Russia, Iran and the Ukraine – have all worked with dolphins: one, to study how they echolocate in the hopes of designing better submarines and sonar detectors. And, two, to train them to listen for approaching submarines, reveal the location of buried explosive devices underwater, and uncover the identity of suspicious objects. I love this book and I love Jacqueline Wilson, but it wasn't my favourite one that she's ever done."

Professor Wenwu Cao in the Department of Mathematics at Penn State Materials Research Institute published a study last year in the journal Physical Review Applied describing how porpoises can use the oily material in their heads (described as a 'meta material') to create narrow beams of sound instead of regular sound waves that travel in all directions.Double Act won the prestigious Smarties Medal and the Children’s Book Award as well as being highly commended for the Carnegie Medal. The Story of Tracy Beaker won the 2002 Blue Peter People’s Choice Award. The Longest Whale Song is very emotional. I have just about finished all of Jacqueline's books and this one is the best so far!" Incredibly, these phrases and themes can change as whales from different parts of the world socialise, creating an acoustic network. I think The Longest Whale Song was really really fab, but it was also a bit sad. The last chapter was really touching and made my eyes water!" Jacqueline Wilson wrote her first novel when she was nine years old, and she has been writing ever since. She is now one of Britain’s bestselling and most beloved children’s authors. She has written over 100 books and is the creator of characters such as Tracy Beaker and Hetty Feather. More than forty million copies of her books have been sold.

I really enjoyed this book even though it's very sad. I marvelled at how she coped without her mum." Dolphin echolocation is so sensitive, they can figure out the size of a fish based on the size of the swim bladder (a sac full of air that fish use to move vertically in the water). Beluga echolocation is even more sensitive. They can discern the shape of an object behind an opaque screen. No human technology can do this. I thought it was absolutely amazing. The way the author portrayed the characters was incredible. Well done!" But what's the purpose of these noises? At the moment, experts have yet to form a complete understanding. However, ground-breaking new research has monitored how songs have spread and evolved throughout the South Pacific, revealing a sprawling age-old acoustic community that may connect whales worldwide – and help them form life-long relationships. I can't wait to get this book, it looks great! I have read the extract from the Jacqueline Wilson magazine so I am already part way into the book!"I am a few chapters in and I already love 'The Longest Whale Song'. It is much more gripping than 'Hetty Feather' and draws you in straight away." This book is great! I loved the facts about all the different whales, although the book is sad in many parts. I would have also liked there to have been a few more chapters!" It's one of the best books I've ever read. It has such a good story line. Jacqueline has told an amazing tale yet again!"
