Manatees are found in shallow coastal waters and rivers in the southeastern United States, the Caribbean Sea, Africa, and parts of South America.

Manatees are gentle giants that spend most of their time eating, resting, and swimming. They are herbivores that feed on aquatic plants. Manatees have poor eyesight but make up for it with their excellent sense of touch. They use their whiskers to help them find food and avoid obstacles.

Manatees are slow-moving animals and can hold their breath for up to 20 minutes at a time.

2. Manatee Behavior Characteristics

A. Manatee Feeding Habits

There are three primary types of manatees: the Amazonian manatee, the West Indian manatee, and the West African manatee.

All three types of manatees are herbivores, meaning that they only eat plants. Manatees are known to eat more than 60 different types of aquatic plants.

Manatees are gentle giants and consume large quantities of vegetation daily. An average-sized adult manatee eats about 10-15% of its body weight in vegetation each day. That’s a lot of salad! Most of their diet is composed of aquatic plants, but they will also consume land plants if they have access to them.

Manatees are particularly fond of certain types of aquatic plants, such as turtle grass, eelgrass, and mangrove leaves.

B. Manatee Habitat

Manatees inhabit shallow, slow-moving rivers, estuaries, saltwater bays, canals, and coastal areas. The warm waters are essential for their survival as they are not able to regulate their own body temperature.

There are several threats to manatee habitat including pollution, development, and boat collisions. Pollution can come from sewage discharge and chemical runoff from agricultural land. Development can lead to the destruction of mangrove habitats and the loss of seagrass beds. Boat collisions are often fatal to manatees and can also damage critical habitats.

Conservation efforts are underway to protect manatee habitat. Creating boat speed zones and educating boaters about manatee habitats is helping to reduce boat collisions. Restoration projects are working to improve water quality and recover lost seagrass beds.

C. Manatee Social Behavior

Manatees are large, aquatic mammals that live in warm waters around the world. Although they are often solitary creatures, manatees have been known to form bonds with other manatees and even other animals.

Scientists have observed manatees forming close relationships with one another and engaging in what appears to be a social behavior. Manatees have been seen touching and caressing each other, as well as playing and chasing one another around.

It is not clear why manatees engage in these activities, but it is believed that they may help the animals relieve stress, build social bonds, and stay healthy. Whatever the reason, manatees are capable of forming strong social relationships with one another.

D. Manatee Mating Behavior

During mating season, male manatees become quite aggressive. They will jockey for positions with other males to mate with a female.

2. Manatees are excellent swimmers and can hold their breath for long periods of time. This allows them to escape predators and navigate through murky waters with ease.

3. Manatees have thick skin that protects them from harsh weather conditions and predators.

4. Survival Behaviors

There are several things that manatees do in order to survive. One of the most important things is to maintain a high body temperature. They do this by spending most of their time in warm waters, often congregating near sources of heat such as power plant effluent or natural springs.

Manatees also have a very slow metabolism, which helps them to conserve energy. Another important survival behavior is avoiding predators.

Manatees are often targeted by large predators such as alligators and sharks, so they must be constantly on the lookout for these animals.

Finally, manatees must eat a lot of food to maintain their large body size. They consume up to 15% of their body weight every day in aquatic plants.

5. Manatee Conservation

Unfortunately, manatees are now endangered due to a variety of factors including boat collisions, habitat loss, and water pollution. As a result, conservation efforts are underway to protect these animals and ensure their survival.

There are several ways that you can help with manatee conservation. One way is to support organizations that are working to protect these animals. You can also help by following guidelines when you’re in areas where manatees live and swim.

Finally, spreading awareness about the importance of conservation can go a long way in helping to preserve these amazing creatures.

6. Frequently Asked Questions about Manatee Behavior

What Are Manatees?

Manatees are large, herbivorous marine mammals known for their gentle nature and distinctive appearance. These gentle giants are commonly found in the warm coastal waters of Florida, the Caribbean, and other tropical regions.

Manatees are part of the order Sirenia, which includes three species: the West Indian manatee, the West African manatee, and the Amazonian manatee.

Manatees are characterized by their round, barrel-shaped bodies, paddle-like flippers, and a prehensile upper lip that they use to graze on aquatic plants.

The West African manatee is found in coastal regions of West Africa, and the Amazonian manatee is native to the freshwater habitats of the Amazon River basin.

Are Manatees Mammals?

Yes, manatees are indeed mammals. They belong to the order Sirenia, which includes not only manatees but also dugongs and the extinct Stellar’s sea cow. Manatees share several key characteristics that classify them as mammals, including:

  1. Mammary Glands: Manatees, like all mammals, have mammary glands that allow them to nurse their young with milk produced by the mother.
  2. Hair: Although they do not have a lot of hair, manatees have bristle-like hairs scattered across their bodies, which are more noticeable in young calves.
  3. Lungs: Manatees are air-breathing mammals, and they must come to the water’s surface to breathe. They have lungs and breathe through nostrils located on the top of their snouts.
  4. Warm-Blooded: Manatees are warm-blooded animals, meaning they can regulate their body temperature internally, which is characteristic of mammals.
  5. Live Birth: Manatees give birth to live offspring rather than laying eggs. The young manatees, known as calves, are born underwater and then nursed by their mothers.

These characteristics firmly place manatees within the classification of mammals, even though their aquatic lifestyle and unique adaptations set them apart from other mammals in terms of their habitat and behavior.

Do manatees eat humans?

No, manatees do not eat humans. The gentle giants of the sea, manatees are often called “cows of the ocean.”

They are large, slow-moving aquatic mammals that graze on seagrasses and other marine plants. Manatees are found in coastal waters around Florida and in the Amazon River basin.

Though they are massive animals, manatees are docile creatures that pose no threat to humans. In fact, they are often the victims of boat collisions and other human-related injuries. Due to their peaceful nature and low reproductive rate, manatees are considered an endangered species.

What Happens If You Touch a Manatee?

If you’re lucky enough to spot a manatee in the wild, resist the urge to touch it. These gentle giants are protected by law and touching them could result in serious penalties.

Touching a manatee is a federal offense and is punishable by fines and jail time. Manatees are protected under the Marine Mammal Protection Act and the Endangered Species Act. These laws were put in place to help conserve manatees and their habitat.

Manatees are at risk of being injured or killed by boat propellers.

What Manatee Behaviors and Characteristics Make Them Vulnerable?

Manatees are gentle, slow-moving mammals that live in warm waters. They are often called sea cows because they graze on seagrass. Manatees are very curious and will approach boats, docks, and swimmers. This makes them vulnerable to being hit by boats or having entanglements with fishing gear.

Manatees have a thick layer of blubber for insulation, but this also makes them slow to react to predators. They give birth to a single calf every two to five years which further reduces their population growth.

Climate change is also a threat to manatees as it warms the waters they live in and decreases the amount of seagrass available for them to eat.


Delving into the intricacies of manatee behavior opens up a world of wonder and concern for these magnificent marine creatures.

From their gentle and herbivorous nature to their intricate communication methods and social interactions, manatees showcase a captivating blend of traits that make them a vital part of our oceans.
