Manatees are strange-looking mammals! They are the only plant-eating mammals in the ocean. Manatees are slow and quiet. They don't jump and play like dolphins.
Manatees are in danger because they like to stay near the shore. When boats go through the water, their propellers get caught on the manatees and kill them. Scientists are trying to save the manatee.
Manatees are also called sea cows, but they look more like a dog than a cow!
