The document summarizes how different animals protect themselves from danger. It discusses how pangolins have hard scales, millipedes curl up their bodies, and garden snails have shells to protect themselves. It also provides examples of how buffaloes, opossums, scorpions, porcupines, centipedes, bed bugs, chameleons, camels, rhinoceroses, desert foxes, and arctic foxes protect themselves through characteristics like thick skin, camouflage, playing dead, or emitting bad smells. Students are asked questions to test their understanding of these protective behaviors.
