The manatee is the gentle giant of the ocean. Thanks to conservation efforts over the years, the West Indian manatee — that's the one you see in Florida — was recently removed from the endangered species list. Take a look at some of the cool and little-known facts about this species and others in the manatee family.
1. Only so many manatee species
Today there are three manatee species found in the world: the Amazonian (Trichechus inunguis), the West African (Trichechus senegalensis) and the West Indian (Trichechus manatus).
2. Bigger than you might think
Manatees can reach up to 13 feet long (depending on the species) and weigh up to 3,500 pounds.
3. Grazers of the sea
Manatees are herbivores, and most of their diet is made up of plant matter. One of their favorite things to eat is sea grass.
Sea cow is also a name for a manatee.
5. Copious chompers
Manatees have four rows of teeth, which include about 24 to 32 teeth total. They lose and replace these teeth often.
6. Lots of family time
Mother manatees are pregnant for about a year. Once the babies are born — they are born directly into the water — it takes another year to year and a half for them to be on their own.
7. Not in a rush
Most of the time, manatees only move at a pace of a couple of miles per hour. However, they can reach up to 20 miles per hour if needed.
8. Over a century of protection

Officials have been trying to protect manatees for a long time. The first laws to protect them in the United States were passed in 1893 in Florida. At one time, there were only about 1,000 West Indian manatees alive, but now there are more than 6,000.
9. Get a lungful of that
Get ready to be impressed by the lungs of manatees. They can stretch almost the entire length of their body.
10. Fans of warm springs
Manatees will gather at warm springs on particularly cold days, including the King Crystal River National Wildlife Refuge. The spot was set aside specifically for manatees to warm up during the winter. (Photo: Joyce Kleen/U.S. Fish and Wildlife Service Headquarters/Wikimedia Commons)
During winter and when temperatures are cooler, manatees will gather in groups at warm-water sources to help each other survive.
11. Any water will do
Since they often go in shallow water, it's common for manatees to move between fresh water and salt water.
12. Surprising family tree
Elephants are distant relatives of manatees.
13. At one with nature
Manatees don't mind a little algae on their bodies. (Photo: Ramos Keith/U.S. Fish and Wildlife Service/Wikimedia Commons)
If you get a chance to see a manatee in the wild, you might notice it has algae growing on it. Don't worry! The algae doesn't hurt them. It might even help protect them from the sun.
14. Plenty of air
When they go underwater, manatees can hold their breath for up to 20 minutes.
15. Solo swimmers
Aggregation is the name for a group of manatees. They don't tend to gather in large groups, though. They usually travel alone or in pairs, but sometimes there will be as many as six together at once.
