Florida Manatee

The Florida manatee is a large, slow-moving marine mammal that is native to the southeastern United States.


Also known as the West Indian manatee, it is a subspecies of the manatee and is classified as a threatened species under the Endangered Species Act.

These gentle giants can grow up to 13 feet long and weigh more than 3,500 pounds.

Florida is home to the largest population of manatees in the world, with more than 6,300 of these creatures residing in its waters.

They can be found in rivers, estuaries, and coastal areas throughout the state, but are most commonly spotted in the warmer waters of the Gulf of Mexico and the Atlantic Ocean.

Overview of Florida Manatee

The Florida manatee, also known as the West Indian manatee, is a large, aquatic mammal that is native to Florida.

They are part of the Sirenia family, which includes sea cows, dugongs, and manatees.

Manatees are slow-moving herbivores that can grow up to 13 feet long and weigh over 3,500 pounds. They are known for their gentle nature and curious behavior.


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.

The U.S. Fish and Wildlife Service estimates that there are around 6,000 manatees in Florida waters, with around 1,500 of them being adults.


Manatees have a unique set of characteristics that make them well adapted to their aquatic lifestyle. They have two fore limb flippers that they use for steering movements and to hold vegetation while feeding.

Their flippers are covered in thick skin and have three to four nails on each flipper. They also have a powerful tail that propels them through the water.

Manatees are also known for their large, whiskered snouts, which they use to locate food.

Florida manatees are typically gray in color and have a wrinkled appearance. They have a thick layer of blubber that helps them regulate their body temperature and provides buoyancy in the water.

Manatees are also known for their unique vocalizations, which include chirps, whistles, and grunts.

Overall, the Florida manatee is a fascinating and important species that plays a vital role in the aquatic ecosystems of Florida.

While they face threats from habitat loss, boat strikes, and other human activities, conservation efforts are helping to protect and preserve this iconic species for future generations.

Habitat and Behavior

The Florida manatee (Trichechus manatus latirostris) is a subspecies of the West Indian manatee and is found in the southeastern United States.

Manatees inhabit rivers, bays, canals, estuaries, and coastal areas, moving freely between fresh, saline, and brackish waters.

They are known to travel long distances and have been spotted as far north as Massachusetts during warmer months.

Warm-water Habitats

Just as important as their ability to move between different types of water is the manatee’s need for warm-water habitats.

Manatees are unable to tolerate water temperatures below 68 degrees Fahrenheit for extended periods of time and can suffer from cold stress syndrome if exposed to cold water for too long.

Florida springs, such as the Crystal River and Blue Spring, provide essential wintering habitats for manatees.

Aquatic Vegetation

Florida estuaries and freshwater lakes, springs, and rivers provide extensive beds of seagrass and abundant freshwater aquatic vegetation that provide the manatee’s primary food sources.

Seagrass meadows are particularly important to the manatee, as they provide both food and shelter.


Manatees are aquatic herbivores and spend up to eight hours a day grazing on seagrasses and other aquatic plants.

A manatee can consume from 4 to 9 percent of its body weight in aquatic vegetation daily.

They use their flippers to pull themselves along the bottom and their lips to grasp and tear the vegetation.

Mating and Reproduction

Manatees reach sexual maturity between 3 and 5 years of age and mate year-round. During the breeding season, males gather in a mating herd and compete for females.

Gestation lasts about a year, and a single calf is born. The calf stays with its mother for up to two years before becoming independent.

The loss of warm-water habitat due to factors such as power plant closures and climate change is a major threat to the Florida manatee population.

Conservation efforts, such as the establishment of manatee protection zones, have been put in place to help protect these gentle giants.
