Which thick-skinned herbivore with horns from Southeast Asia and Africa?

• A. Hippopotamus
• B. Bison
• C. Yak
• D. Rhinoceros

Answer: (D)

Think about an herbivore known for very thick, protective skin and a horn on its snout, with species living in Africa and parts of Southeast Asia. That combination points to the rhinoceros. Rhinos have tough, thick skin and one or two horns made of keratin. They graze on grasses, leaves, and shrubs. In Africa you have species like the white and black rhinos, while in Southeast Asia you find the Sumatran and Javan rhinos. The other animals either don’t have horns, or aren’t native to both Africa and Southeast Asia, so they don’t fit all parts of the description.
