Read the excerpt from the story Animals in the Zoo. "Don't worry, we won't be operating on the tamarins today. We are just checking their health and looking at their eyes, ears, and hands during this visit. We want to make sure they are healthy enough to be put into their enclosure," she said. Just then, a zoo employee brought in the two tamarins, and Ryan immediately understood why they were called cotton-top tamarins. Each of them had a white tuft of hair on top of their head. The zoo employee told Ryan and his mom that these two tamarins were the first of many to come to the zoo. If these two stayed healthy and appeared to be happy in their enclosure, the zoo would be able to get even more tamarins to fill the exhibit which is why they wanted to make sure they had an expert come in to examine them.

It took Ryan's mother 30 minutes to check each tamarin. She wanted to make sure they both had thorough examinations. Finally, after an hour, she gave them both the all clear.

One of the tamarins was looking right at Ryan and had her arms stretched out. Ryan looked at his mom with an inquiring gaze. She nodded at him, so he reached out and picked her up from the examination table. The tamarin licked the end of his nose, and Ryan laughed. He definitely would be back to visit the tamarins as soon as he could.
