A tongue-in-cheek field guide to the animal kingdom, ranked by how horrible it would be to die in their jaws or at the ends of their claws. Let's be clear: Mamadou Ndiaye knows a whole lot of animals that can and will end you, but he has no plans to let these strange and horrifying creatures cash in his life insurance policy. Now the TikTok star is turning his engaging, entertaining, and informative takes on animal biology and behaviour into this hilarious guide to the world's most deadly animals. In 100 Animals That Will F*cking End You, you'll acquire a healthy fear of the massive Southern elephant seal, which is built like a truck with the personality of a Spring Break frat boy, sperm whales with a call so strong it can vibrate you to death, meerkats or the most homicidal mammals on Earth, hyenas, which eat their prey while it is still alive, hippos, which have no soul and answer to no god, and a Portuguese Man O'War, a species of siphonophore armed with millions of explosive stinging cells powerful enough to make Nemo an orphan and occasionally turn a person into past tense. From the moose (aka the antlered Grim Reaper) to the Cassowary (Jurassic bullshit with feathers), this is nature like you never want to meet it in real life.
