This third book in the Extraordinary Animals series delves into the mind-bending world of amazing animal brains. Real-life animal brainiacs and the scientists who study them come to life in this detailed look at how animal--and human--brains work and the incredible things they can do. Meet goldfish who drive their own special car in search of treats; brilliant octopus problem-solvers who can probe, taste, and even make decisions with their arms; and squirrels who use mnemonic devices to remember where they've hidden their nuts! Readers will explore brains large and small, smooth and wrinkly, through fascinating sidebars, plenty of real science vocabulary, and full-color illustrations and photos. They can even put their own brains to the test through DIY neuroscience activities, from honing memory skills to getting focused through meditation. This engaging book delivers lots of fascinating science and the opportunity to learn more through a "further exploration" section, source notes, and a bibliography.
