Book 33, Question 20
Which mammal has scales?
A pangolin looks like a scaly lizard, but it is a mammal.
Its hard scales are made of keratin, the same material as your fingernails. Pangolins live in Africa and Asia and eat ants and termites. When frightened, a pangolin curls into a tight ball. It also nurses its baby with milk, which proves it’s a mammal.
