Margie Robinson, age 9, of Columbia, Tenn., for her question:

HOW LARGE DOES A LLAMA GROW?

The llama is the largest member of the South American branch of the camel family. It grows to be about four feet tall at the shoulder and is about four or five feet long. The llama does not have a hump.

In South America, adult male llamas are used as pack animals. They can travel from 15. to 20 miles a day and may carry a pack weighing about 100 pounds. Sometimes hundreds or even thousands of llamas are used on an engineering project.

The llama can be a very stubborn animal. If he feels his pack is too heavy, or if he thinks he has worked hard enough, he will lie down with his front legs under him and refuse to move.

When under attack or angry, a llama can spit a bad smelling saliva into his enemy's face.

Female llamas are used for breeding and for fur. The hair is used to make garments and the hide is used to make sandals.
