Set a Purpose for Reading
As students read, have them think about why the baby manatees needed human help.

1. Why did rescue workers need to step in to raise the three manatees?
Rescue workers needed to step in to raise the three manatees because the animals had been found swimming alone without their mothers to care for them. The article explains that “manatee calves stay with their mothers for about two years. But these babies’ moms were nowhere to be found.”

2. According to the Words to Know box, what are herbivores? What clues in the article help you understand the word’s meaning?
The Words to Know box explains that herbivores are animals that eat only plants. One clue in the article that helps you understand this meaning is that “most adult manatees eat about 100 pounds of seagrass a day.” Another clue is the phrase “graze so much.”

3. Why did workers at the Cincinnati Zoo arrange vegetables at the bottom of a tank to look like seagrass?
Workers at the Cincinnati Zoo arranged the vegetables at the bottom of the tank to look like seagrass in order to help the manatees learn how to look for seagrass. This would help prepare the manatees for their return to the wild.
