Manatees sleep at the bottom. They are mammals and are related to elephants. They live in warm water. Manatees are usually slow but they can get fast. Manatees are very friendly and they like getting scratched on their chin and chest.
Manatees can live in fresh and salt water.
Manatees drink fresh water. They can stay without fresh water for a long time. They live in Florida in the ocean and everglades. They start in north Florida and they go all the way down past the Amazon River. I've seen them in the Miami Seaquarium and Sea World.
