"Genius Ears: A Curious Animal Compendium" is an illustrated non-fiction book for young readers, roughly ages 6-12, that explores the astonishing variety of ears found across the animal kingdom and the many jobs they do beyond simply hearing.
Through detailed ink and coloured-pencil illustrations paired with bite-sized, fact-filled text, it shows how animals use their ears for defence, temperature regulation, communication, balance, and pinpointing prey. From the black-tailed jackrabbit's ears, which help it dodge predators, to species that can locate food by sound alone.
Part of the Genius Animals series, from the creators of "Genius Noses", it poses fun, curiosity-driven questions, such as which animal has the longest ears relative to its body size, to introduce young readers to zoology and sensory biology in an engaging, browsable format.
