Today there are more than 6, in Florida, representing a significant increase over the past 25 years. Manatees are large, elongated marine mammals with paired flippers and a large, spoon-shaped tail.
They can reach lengths of over 14 feet and weights of over 3, pounds. Manatees are typically greyish brown in color. They have sparse hairs spread across their bodies, with bristles about the muzzle.
Manatees live in marine, brackish, and freshwater systems in coastal and riverine areas throughout their range. Preferred habitats include areas near the shore featuring underwater vegetation like seagrass and eelgrass. They feed along grass bed margins with access to deep water channels, where they flee when threatened. Florida manatees can be found throughout Florida for most of the year. However, they cannot tolerate temperatures below 68 degrees Fahrenheit for extended periods of time, and during the winter months these cold temperatures keep the population concentrated in peninsular Florida.
Many manatees rely on the warm water from natural springs and power plant outfalls. During the summer manatees expand their range, and on rare occasions are seen as far north as Massachusetts on the Atlantic coast and as far west as Texas on the Gulf coast. Manatees feed on plants. They prefer submergent vegetation, such as turtle and manatee grass, and will feed on floating and emergent plants as well.
Manatees also require freshwater for drinking. Historically, West Indian manatees were found along the U. However, due to hunting, habitat fragmentation and loss, and other factors, manatees have disappeared from various parts of their range.
For example, manatee hunts were common until the early s, and as a result the species is no longer found in Guadeloupe and other islands in the Lesser Antilles.
Today manatees are found in the southeastern U. In the U. For other places to view manatees visit myfwc. Within the U. To reduce the effect of collisions on manatees, boat operators are required to slow down and or avoid regulated areas commonly used by manatees. The U. Fish and Wildlife Service, the Florida Fish and Wildlife Conservation Commission, and others designate, mark, and enforce manatee protection areas.
Following extensive review of the threats the manatee faces as well as the conservation actions currently in place to help recover it, the Service reclassified the species as threatened on March 30, View the Recovery Plan. Primary threats to the West Indian manatee include habitat loss and fragmentation, entanglements in fishing gear, collisions with boats, and others. The most significant problems presently faced by Florida manatees is the loss of warm water habitat, and death and injury from boat strikes.
Natural threats can include harmful algal blooms, cold weather, tropical storms and hurricanes, tidal entrapments, and disease. We work with federal, state, academic and non-profit organizations across the southeastern United States and Puerto Rico to conserve manatees. Outside the U. Sirenia Project biologists work cooperatively with federal and state researchers and managers on research identified as essential for the recovery of the species.

Officials have said that the "downlisting" does not change federal and state protections for the animals, which were put on the endangered list in March They say the move shows various partners have worked to increase the population numbers and protect habitat. Read More. The action came about a month after Florida officials said that for the third straight year, spotters counted more than 6, manatees.
By contrast, just a few hundred manatees were counted in the s, officials said. Christopher Burke, 9, pleaded for officials to keep the current status: "I'm so happy that manatee population is increasing! But at the same time hopping you will not stop protecting them! Please don't down list manatees. I LOVE manatees and got my best friend to love them too. The US Fish and Wildlife Service, which manages manatee refuges and sanctuaries, last year proposed reclassifying the West Indian manatee , which includes the Florida manatee.
