I bought this for my biologist sister and literally upon opening it, she was debunking "fact" after "fact" as false! Then I glanced through it and found myself doing the same thing - mostly about stuff I don't consider myself remotely knowledgeable on! So you have to end up taking everything here with a pinch of salt. I honestly can't see how it got published, it is just a hopeless mishmash of stuff the author probably found on the internet and didn't bother to verify.
OK, here is a FRACTION of the portion of untrue factoids.
"The May fly [should be one word] lives only six hours, but its eggs take three years to hatch" The mayfly does indeed have a short lifespan (ranging from 2 hours to 14 days, in fact). Eggs hatch immediately, or take up to 11 months, never 2 years!
"A dragonfly has a lifespan of 24 hours". Again, false - they live at least a few weeks. But hey, what's this? Just a few pages later comes the more accurate "A dragonfly has a lifespan of four to seven weeks."
"The slang word crap comes from T. Crapper, the man who invented the modern toilet." Thomas Crapper did not invent the toilet, nor does the word "crap" have anything to do with his name, having existed over 200 years before he was born.
"A chicken is the only animal that can be eaten before it is born and after it is dead." Not true.
"The elephant is the only mammal that cannot jump." Again, false.
And ditto "the original name for butterfly was flutterby".
Those are the ones I could be bothered to share, but you get the idea.
There's also the downright sloppy grammar/proofing; forgetting the 'G' in Grace Kelly's forename, "Belgium town" rather than "Belgian town", "The world's termites outweigh [outnumber surely] the world's humans ten to one", "butterflies taste with their feet" closely followed by "butterflies taste with their hind feet" and many more. And the categorisation baffles "The International Association of Women Helicopter Pilots is known as the Whirly Girls" makes it into the "Literature and Art" chapter, as do several other facts that have no place there.
But I'll leave you with a fact this book has to share that I'm sure is completely true.
"No two cornflakes are the same".
