Manatees are often called sea cows, but that name doesn’t do them justice, even though they may weigh as much as a full-grown cow. These enormous ocean animals can cruise along underwater at as fast as 15 miles per hour. They have strong tales that propel them gracefully through the water. Beginning readers learn about where manatees live, what they eat, how they move, and much more, all while enjoying beautiful photographs of manatees with each turn of the page.
