i'm glad to see that squirrels get their own chapter. too bad llamas have to share with giraffes and camels. but i'm actually downloading this book for chapters twenty-three and twenty-four.

Llamas and camels are both members of the same family "camelidae". Although they are found on different continents they are extremely closely related and have been successfully interbred by artificial insemination (the result is called a "cama").
