Why is the manatee in danger of extinction?
- The dugong has an arched tail similar to that of a dolphin, while that of the manatee is spatula-shaped and flattened.
- The dugong has very characteristic lips that protrude to the sides, so the face is very different.
- The skin of the dugong is softer than that of the manatee.

Why are manatees hunted?
The the West Indian manatee has no known predators other than humans. In the past, humans hunted manatees extensively for their meat, fat, and tough hides. In some parts of the Caribbean and South America, manatees are still hunted for food.
Why are manatees on the endangered species list?
Crosby said the deadly problem manatees are facing in Florida is mainly due to poor water quality. “We have to focus our efforts on getting sea grass back,” he said. Red tide and poor water quality, specifically in Central Florida, has killed off hundreds of acres of sea grass — the primary food source for manatees.
When did manatees become endangered?
1967Manatees were classified as "endangered" under the Endangered Species Act in 1967. Then, in 2017, their status changed as the U.S. Fish and Wildlife Service downgraded them to "threatened." It's an improvement but not much of one.

Is the West Indian Manatee endangered?
Currently it is listed as threatened as it was recently moved off of the endangered species list. However, that doesn't mean this species of animal is safe despite an estimated population of at least 13,000 , and it can easily become endangered once again in the future. This lesson focuses on the West Indian manatee but be aware that two other vulnerable species of manatee exist in the world.
Do manatees fear alligators?
What's interesting to note is that manatees need not fear Florida's fearsome alligators. Nothing in the wild likes to snack on manatees and alligators are happy to let manatees pass them by in the water. But manatees do need to fear boats. Boats hit, slice through and kill manatees every single year. Watercraft collisions are one of the biggest threats to the manatee's survival.
Why are manatees losing their habitat?
The loss of habitat is one of the major threats to their survival. Manatees cannot rely on blubber to stay warm during winter like other sea mammals. When the temperature drops, manatees need to get warm, or they could die.
Why are manatees dangerous?
They are also in danger of collision with fast-moving watercraft because they are slow swimmers and cannot dive deep enough to avoid them. Almost 100 manatees were killed just by boats in the year 2009., in Florida.
Why are manatees called sea cows?
Manatees are also known by the name of "sea cows" because of their physical characteristics and fondness of seagrass. But, not many people know that manatees are also related to elephants. They did not evolve from elephants, but they share the common ancestors because they are both a part of the group of mammals called tethytheria. Sure, they are both grayish and have wrinkled skin, so that might not come as much of a surprise. Even though they are relatively large animals, weighing almost 1,200 pounds, they are surprisingly graceful in their behavior.

It might help to wear polarized sunglasses, according to the Florida Fish and Wildlife Conservation Commission (FWC), ...
What happens if a manatee responds to your presence?
If a manatee responds to your presence, you are already too close, the FWC warns. Manatees who frequently interact with friendly paddlers can lose their natural caution around watercraft of all kinds, including the motorized vessels that already maim and kill too many manatees.
How do humans kill manatees?

How to help manatees recover?
Whether you live near a manatee habitat or just take a vacation there, you can assist their recovery by making even a minimal effort to clean up hazardous trash. That could mean joining a coordinated cleanup event at a shoreline, park, river, or roadside, or simply picking up a little trash as you walk along the beach.
What to do if you hit a manatee on a boat?
If you do collide with a manatee, make sure to report it quickly . Boat strikes often don't kill manatees immediately, so prompt rescue efforts can save their lives.
What are the dangers of entanglement?
As with many marine mammals, entanglement in fishing lines and nets poses another grave threat to manatees. Although people do target manatees in some places with traps, nets, and baited hooks, they are also widely killed by fishing gear intended for other animals. This can happen to both adults and juveniles, and unless humans find them in time to help, entangled manatees generally have slim chances of survival. Many drown, and those who manage to surface for air may still be unable to move around easily enough to survive for very long.
How to help a manatee?
If you see a manatee, one of the easiest ways to help is by giving it plenty of room. Even if you only see one, it might be traveling with others — like a calf — that are out of view. Manatees can become confused by multiple boats, sometimes swimming away from one and into the path of another.
Description
Florida manatees are large, herbivorous mammals. These big mammal species can be found in Florida’s waterways. These species are often mistaken for mermaids because of their human-like flippers and long, plantigrade tails that resemble a mermaids’ hair.
Conservation Status
These species are now on the endangered species list due to Florida’s waterways. They are often seen as a threat to Florida’s economy and conservationists believe that manatee numbers have been increasing over recent years.
Final Thoughts
Florida Manatees are a Florida icon, and they’re also surprisingly endangered. They can be found in Florida waterways near shorelines, which is why it’s so common for them to become entangled in fishing gear or killed by boats that don’t follow boat speed restrictions.
Harmful Algae Blooms Have Killed The Seagrass
Among the most important habitats in the world for the iconic charismatic manatee is the Indian River Lagoon, which stretches five counties from Brevard near the state’s midsection south to Palm Beach County.
Bracing For More Deaths
The calamity now has prompted an urgent federal and state effort aimed at bracing for potentially more deaths this coming winter, as the Indian River Lagoon’s water quality problems and seagrass losses will not be resolved anytime soon.
For Starving Manatees, A Lengthy Recovery
Among the manatees rescued this year were 13 orphaned calves. At least two ended up at the SeaWorld rehabilitation center in Orlando, in a tank not far from No. 37’s.
How many manatees died in Florida in 2019?
Vessel-related deaths reached a new peak in 2019, with 137 manatees stuck and killed by boats , which tops the previous record of 124 vessel-inflicted mortalities set in 2018. Manatees can also be killed by neurotoxins associated with red tides that occur most often in southwest Florida.
When did the Florida Manatee get downlisted?
In April 2017, FWS officially downlisted the species. In its final rule, the agency cited that the West Indian manatee had met the downlisting criteria established in the 2001 Florida Manatee Recovery Plan and thus warranted reclassification from endangered to threatened.
What are manatees in Florida?
Manatees are herbivores, feeding solely on seagrass, algae and other vegetation in freshwater and estuarine systems in the southeastern United States. Florida manatees can be found as far west as Texas and as far north as Massachusetts during summer months, but during the winter, manatees congregate in Florida, as they require warm-water habitats to survive. Abundance of the subspecies has increased over the last 30 years, which recently prompted the U.S. Fish and Wildlife Service (FWS) to downlist the West Indian manatee from endangered to threatened. However, due to their slow speed and relatively high buoyancy, manatees are often struck by vessels, which is the primary cause of human-related deaths of the species. Additionally, manatees continue to be threatened by loss of warm-water habitat and periodic die-offs from red tides and unusually cold weather events. Florida manatees are managed jointly by both FWS and the Florida Fish and Wildlife Conservation Commission (FWC).
Is the West Indian Manatee endangered?
Fish and Wildlife Service (FWS) to downlist the West Indian manatee from endangered to threatened.
Is the Florida manatee a subspecies?
Fish and Wildlife Service (FWS), we submitted a letter recommending that the two subspecies, the Florida manatee and the Antillean manatee, be considered separately. The Commission noted that despite an increase in the population size of Florida manatees, the growth of the population over the past 30 years has remained slow while manatee mortalities continue to reach record highs. We also expressed our concern with the loss of warm-water habitat due to eventual retirements of power plants over the next 30 to 40 years. This could threaten the future manatee population in Florida and reverse past recovery progress.
