Why are there so many beetles? (That We Know Of) | Lindsay Nikole

Why does one single insect order account for a quarter of all known animal life on Earth? The answer to "why so many beetles?" turns out to be a three-part evolutionary story involving armored wings, survival through mass extinctions, and a genetic heist stolen straight from bacteria and fungi. Along the way, meet nature's strangest beetles: the bombardier beetle that cooks up explosive chemical sprays inside its own body, the trilobite beetle with females stuck in a permanent larval form, the "unkillable" diabolical ironclad beetle that can withstand being crushed by 39,000 times its body weight, and the Namib Desert fog beetle that harvests drinking water from morning fog. Nature's most successful animal group is way weirder than you think. #LindsayNikole #beetles #bestmattressever #Helixmattress #luxurymattress Oh!
