An Immense World

 We humans rely on our vision for interpreting the world. Other species are less visual. All this is explained in the book An Immense World: How Animal Senses Reveal The Hidden Realms Around Us by Ed Yong. Each chapter is a different sense. Some of his examples are mind boggling. Dolphins can echolocate a human in the water. With their ability to hear ultrasound, dolphins sense not only a human body but the organs and bones inside the human. The author writes about a German word, umwelt, which means the perception abilities of a particular animal. Each species has differences. Some species see better at night but not so well in the daytime. Some animals, like dogs, can learn more with their sense of smell. No animal can sense everything well because that would be overwhelming. Mosquitoes can sense carbon dioxide. If they sense carbon dioxide and heat, then they go in for a landing. I really wish I could hide my carbon dioxide from them. I thought this book was very educational and fairly easy to read.
