Manatees teeth are all molars. Manatees lose their front teeth, new molars come up in back and the all move forward to fill missing teeth gap. Only mammal to do this. Manatees have no predators. Manatees go out into Tampa Bay when it's 68 degrees or above. Under 68 degrees they hang out in water next to power plant which is 92 degrees year round. Manatees flipper skeletal structure is like our arm skeletal structure. Manatees are also called sea cows. Cow on land or water eat grass. A manatees eat 10% a day if their body weight. Average weight being 1500 pounds. I love learning new things and revisiting things I may not use daily.
