The world is full of animals with strange shapes, dangerous defences, and bizarre habits. The Ugh! Yuck! and Whoa! series highlights the most extreme among them: the grossest, the deadliest, and the ugliest! Learning about lesser-known creatures they may never have seen before helps children to better understand ecosystems and the natural world.
Yuck, That's Gross! is all about animals that behave badly.
