100 Animal Trivia Questions For a Wild Journey Through the Animal Kingdom

I’m an animal lover, so I may be a bit biased when I say I believe animals are one of the very best parts of life on planet Earth. But seriously—we get to live in a world where we can adopt cuddly dogs and cats who live in our houses, where we can watch birds soar through the skies and where we can travel and see humpback whales and dolphins leaping out of the waves. From hummingbirds and butterflies shining beautiful colors while sipping nectar from flowers, to fearsome jaguars slinking through the jungle and emerald serpents below, it’s hard to deny that the animal kingdom is an extraordinary place. Humans have always been fascinated by the animals that share the earth with us, and many have dedicated their lives to studying their behavior and habits. Over the years, we’ve learned more about how animals function and have come to understand that many of them have extremely complex social systems, emotions, and ways of life. Animals also play key roles in balancing out ecosystems that are critical to human existence on Earth as well. Sadly, today, over one million animal and plant species are at risk of extinction. But learning more about animals can help us fall in love with them a bit more, reminding us of the majesty of the natural world. Plus, animals are just plain entertaining and often hilarious—there’s a reason that the Internet really hit its stride as a place for cat videos.
