Animal Superpowers

Animal SuperpowersPhysics and Biology of the ImpossibleCourse-ResearchSeries 'In Twelve Evenings'  Book 30Vita HarwoodWhat Do I Already Know About This?Test your knowledge!What if the most impossible-looking powers in nature are not impossible at all?A bat can navigate in darkness by reading echoes. A gecko can cross a ceiling without glue. An electric eel can turn ion gradients into a powerful discharge. A mantis shrimp stores energy like a spring-loaded mechanism. Squid and octopuses can alter colour, pattern, and even the texture of their skin. Tardigrades can survive extreme dehydration, while an axolotl can rebuild a lost limb.Animal Superpowers: Physics and Biology of the Impossible follows twelve of these biological puzzles and asks the question behind every spectacular claim: how does it actually work?Each lesson begins with an ability that seems to break the rules, then traces it back to the rules themselves. Readers explore echolocation, magnetic sensing, infrared detection, microscopic adhesion, bioelectricity, ultrafast biomechanics, bioluminescence, structural colour, muscular skin control, defensive chemistry, anhydrobiosis, and regeneration. The book also marks the boundary between what scientists know well and what is still under investigation.This is not a catalogue of records and it does not treat animals as superheroes in disguise. It is a short course in how evolution builds remarkable systems from ordinary physics, chemistry, cells, tissues, and nervous systems.For anyone who has ever wondered how a bat 'sees' with sound, why a gecko does not fall, how an animal can make its own light, or why some bodies regenerate better than ours, this book offers the mechanisms behind the wonder.
