Hidden Creature Features

Some animal features are easy to see-long tails, large wings, patterned fur, or sharp beaks. But look closer-you might be surprised by what you find!

A penguin's sharp beak hides a textured tongue that helps it grip fish. A red-eyed tree frog has a golden eyelid that covers its eyes so it can see predators while it sleeps. A platypus fends off predators with a venomous spur. Rhyming text and eye-catching photos offer an up-close look at lots of fascinating hidden creature features!
