Book 32, Question 115
Why does a blue-tongued skink stick out its bright tongue?
A blue-tongued skink is a harmless lizard from Australia.
It has a bright blue tongue that looks surprising against its pink mouth. When it feels threatened, it opens its mouth wide, hisses, and sticks out the tongue. The sudden flash of color startles other animals, and the skink gets a chance to leave. It’s a colorful bluff.
