In IMMENSE WORLD, Yong introduces the concept of animals' "umwelt," the environment or surroundings perceived from the animals' standpoint. Through comprehensive research and interview, Yong breaks down these senses into 11 chapters and bring the readers on a journey to experience the world through their perspective.

I love that Yong explains complex scientific concepts in simple terms; his compassion and empathy for understanding the world through the lens of animals is another theme beautifully explored in the book. IMMENSE WORLD is a perfect read for animal lovers.

Some fun facts from the book:
