Overview of Manatees as a species
Manatees, commonly known as “sea cows” are herbivorous marine animals. These species inhabit marshy and shallow coastal areas and their primary food is saltwater and freshwater plants. Usually, manatees appear in gray colors, however, Amazonian manatees sometimes have pink or white patches.
These aquatic mammals have a paddle-shaped tail and a flat top around the middle and manatees are quite large in size. Manatees are slow-moving animals who are completely harmless and appear to be calm and peaceful.
Broadly, there are three types of species of manatees, the Amazonian Manatee, the West African Manatee, and the West Indian Manatee.
According to studies, manatees have a life span of 60 years however due to man-made destructions such as collisions with propeller-driven ships, boat strikes, litter, fish traps, etc. Besides, some manatees can die of diseases or natural calamities like an increase in water temperature or attacks by crocodiles.
Importance of the Florida Keys as a habitat for Manatees
Manatees are known as endangered species due to their frequent deaths caused by human destruction. Their slow movement does not allow them to escape the danger near them. Manatees are the state marine mammals of Florida and they usually habitat in warm springs to keep their body temperature warm.
Since Florida has the maximum number of springs, it has naturally become the largest habitat place for manatees and hence the Florida Keys plays an important role in the conservation and protection of manatees. Over the years, the regions of Florida Keys have developed artificial powers to keep the temperature of the water warm to support manatee habitat.
Besides the Lignumvitae Key Management area has more than 10,000 seagrass habitats which form an integral part of the manatees’ living ecosystem. Florida manatees contribute to a large number of plant growth in canals, bays, estuaries, and shallow rivers in the Florida Key regions.
In this article, we will explore the lives of manatees in the Florida Keys, shedding light on their behavior, habitat, conservation status, and the measures being taken to ensure their continued survival in this enchanting corner of the world.
Manatee Species and Characteristics
The West Indian Manatee is divided into two subspecies Florida Manatee and Antillean Manatee. Manatees which are aquatic mammals love to live in warm coastal areas and they are usually seen in herds. Although they can move between saltwater and freshwater, they prefer to stay in freshwater environments.
Due to their body weight, and low metabolism, manatees thrive in warm waters. This subspecies is seen along the Florida coast, and also along the Gulf of Texas, and even in North Carolina.
Physical characteristics and adaptations of manatees
The West Indian manatees are typically grey in color and sometimes they appear in light brown or black colors as well. They have wrinkled skin which is scattered with hair or algae. Their physical appearance resembles a lot of seals and they have paired flippers and a paddle-shopped tail.
Known as the relative of elephants, manatees have a prehensile snout that has a resemblance to the trunk of the elephants. It helps them to grab food. They have a tooth conveyor belt that keeps on producing unlimited teeth which helps them to have vegetation. They weigh between 440-1320 lb and they are about 2.5-.3.5 meters long.
Overview of manatee behavior and social structure
Manatees often roam around in solitary and due to their habitats they have grown in areas with a lack of predators. So, generally, manatees lack predator-attack behavior. Also, their huge size has contributed negatively to their speed and they take deep and long dives into the water.
Their swimming speed is 3-5 miles an hour. West Indian manatees thrive on food such as algae, floating vegetation, and seagrasses. Daily they consume up to 10% of their body weight in vegetation. For communication, manatees rely on chirps, squeaks, and whistles. The sounds are extremely important during their mating seasons.
Female manatees have natural motherly instincts and they also use vocalizations to the community with their calves. Mother manatees nurse their claves for up to one to two years providing essential care and protection.
The mating season takes place in the spring season, and male manatees compete against each other to get the attention of the females. The mating process is a complex one where the males engage in elaborate displays to attract another female mate.
Contrary to other mammals, manatees do not engage in long-term social bonds or permanent group structures. They limit their social interactions to mating and raising their offspring.
Description of the Florida Keys as a unique ecosystem
The unique ecosystem of the Florida Keys plays a vital role in the lives of the manatees. Manatees are warm-water dwellers and they seek environments with stable temperatures to avoid cold stress in their bodies. The proximity to the Gulf of Mexico and Gulf Stream allows the regions in the Florida Keys to have warm waters throughout the year.
The temperature becomes essentially useful to manatees during colder months. Additionally, the protected bays and shallow waters of the Florida Keys, provide a safe sanctuary for the endangered species of sea cows.
Freshwater is another criterion for the manatees to have a protected life as they use it for drinking purposes. The rivers, natural springs, and estuaries of Florida Keys provide abundant natural sources of freshwater to these marine mammals.
The Florida Keys community is consistently working on increasing manatee awareness, manatee protection zones, and manatee sanctuaries to protect precious wildlife. Organizations and researchers work relentlessly and with the utmost care to establish safe boating practices, and raise awareness about manatee conservation.
Importance of seagrass beds for manatees
Since manatees are herbivorous sea animals, their diet consists of seagrass and other aquatic plants. The vast accessible seagrass beds of the Florida Keys make it a natural habitat for the manatees. The seagrass beds offer a plentiful and nutritious food source for mammals.
Also, the seagrass meadows act as important feeding grounds and provide a safe environment for the manatees to graze leisurely which helps them to build a sustainable life.

Factors affecting manatee migration patterns in the region
Various factors such as environmental, and biological influence manatee migration patterns in the Florida Keys region.
- Habitat loss occurring due to fuel-led boats and ships is one of the primary reasons for changing migratory patterns in manatees. Since manatees heavily rely on the seabed for their diet, polluted seagrass beds do not allow them ample nutrition.
- Also, manatees require warm water to survive and the effects of climate change impact the temperature and levels of water.
- Boat traffic and collisions with boats are other reasons for their changing patterns. They are slow-moving creatures and try to avoid busy waterways to protect themselves.
Conservation Efforts and Challenges
In 1973, under the Endangered Species Act manatees were listed as endangered. Almost 20% of manatee deaths happen due to boat collisions. Also, fishing gear entanglements and regular constructions on the waterways are polluting the water and the food such as algae which the manatees consume.
When they consume such contaminated water and food they are unable to fight back against it. As to recent statistics, there are 13000 manatees and more than 6500 are in the United States and Puerto Rico. 800 manatee deaths were reported in the year 2022 due to starvation and lack of food.
Manatee protection laws and regulations in the Florida Keys
Manatees are protected under the Marine Mammal Protection Act of 1973 and the Florida Manatee Sanctuary Act of 1978. Apart from the laws, there are certain rules and regulations laid out by the government to ensure the protection of the endangered species of manatees.
It is prohibited to give food or water to the manatees while people are snorkeling with manatees or swimming with manatees in Florida. Human disturbance to manatee mating herds, fishing manatees, or blocking their paths are also not permitted and strict legal measures are taken against those who commit these crimes.
Threats to manatees in the region
- Habitat Loss– Manatees naturally prefer freshwater habitats such as rivers, coastal areas, and estuaries. However, due to constant urbanization and development, there has been a degradation in these habitats making it difficult for manatees to survive.
- Boat strikes– Injuries and death of manatees due to boat collisions are extremely common. As slow-moving creatures, manatees are vulnerable to high-speed boats which lead to death.
- Water pollution– Industrial waste, and petroleum pollution in the water for boats and ships contaminate the water where manatees live. This polluted water often leads to toxic algal bloom which is a food source for the manatees and is extremely harmful for their health.
Conservation initiatives and organizations working to protect manatees
Save the Manatee Club, Manatee Rescue & Rehabilitation Partnership, Florida Fish & Wildlife Conservation Commission (FWC), Clearwater Marine Aquarium, Sea to Shore Alliance, U.S Fish & Wildlife Services, Florida Manatee Program are some of the reputed organizations that are working to protect manatees.
Responsible boating and watercraft guidelines around manatees
Responsible boating practices will ensure the precious lives of the sea cows. Areas where manatees are seen are often marked as “ Slow zone” or “manatee zone” which indicates that the boats and watercraft should decrease their speed to allow the manatees to avoid collisions.
It is important that all boat drivers keep their eyes on the water to spot any snouts or ripple water and maneuver around them. Maintaining a safe distance of 50 feet away from the manatees can also prevent accidental injuries.
Educational programs and tours for learning about manatees
Florida Keys Eco-Discovery System, Dolphin Research Center, the Turtle Hospital, Florida Keys Aquarium Encounters, and Islander Watersports are some of the notable organizations that provide manatee education programs in the Florida Keys and educate people about manatee habitats and seagrass beds in the Florida Keys and Manatee population growth and recovery in the Florida Keys.
