What Do Manatees Eat? and Other Fun Facts About Manatees

Manatees are gentle marine mammals with big appetites, unique bodies, and fascinating habits. From their plant-based diet to their warm-water migrations, sea cows are full of surprises.

Manatees, commonly known as the 'sea cow', are different than most other types of marine life. They need air to survive, and they drink fresh water. They don't have vertebrae in their neck that would allow them to turn their heads. To see in an opposite direction, they must move their entire bodies. In short bursts, manatees can swim up to 15 miles per hour.

There are so many interesting facts about manatees out there. Everything Manatee aims to help ensure the health and survival of the manatee species. We are here to inform others about the sea cow.

Read on to learn everything that you've ever wanted to know about manatees, including "What do manatees eat?"

10% Manatees may eat up to 10% of their body weight daily.
60 Years Manatees can live for decades in the wild.
68°F Manatees seek warmer water when temperatures drop.

Quick Answer: What Do Manatees Eat?

Manatees mostly eat aquatic plants and vegetation such as seagrass, turtle grass, shoal grass, algae, hyacinth, and other wetland plants. They are mostly herbivores and can consume a large amount of vegetation each day.

What Is the Manatees Scientific Classification?

Manatees are in the Mammalia class. They are considered to be from the Sirenia. They belong to the family of trichechidae and dugongidae.

The different types of manatees might include:

Scientific Names
  • Trichechus manatus or West Indian Manatee
  • Trichechus senegalensis or West African Manatee
  • Trichechus inunguis or Amazonian Manatee

They have flippers that help them to swim in the strong currents of coastal waters and to navigate through shallower waters where they might live. It is possible that the manatee may have inspired folklore about mermaids.

How Long Do Manatees Live?

Manatees live approximately 60 years. The oldest living manatee lived to be 69 years old before dying in an accident at the aquarium.

Their long lives make conservation even more important. Protecting adult manatees helps preserve the population for future generations.

Where Do Manatees Live?

Even though manatees live in the water, they still need to surface for air. They take up residence in warm tropical and/or subtropical waters. These might be rivers, bays, canals, estuaries, lagoons, and coastal areas. They can be found in the coastal waters of Florida, the Caribbean, South Africa, and the Amazon.

Manatees often prefer shallow areas where food is easy to reach and where warmer water is available during colder months.

Do Manatees Migrate?

Yes! Manatees love the warmer waters. When their preferred water spots drop below 68°F, they will move to warmer waters for the colder seasons.

Why Warm Water Matters

Manatees do not tolerate cold water well. When water temperatures drop, they search for warm springs, power plant outflows, and other warm-water refuges.

What Do Manatees Eat?

Manatees are mostly known to be herbivores, though they have been known to eat fish. The manatee diet is made up of a variety of different wet vegetation and plants including turtle grass, shoal grass, algae, hyacinth, and acorns. They need to eat up to 10% of their body weight daily. This means that they consume between 32 and 108 pounds of food. They also need to drink fresh water.

Because manatees spend so much time eating, healthy seagrass beds and clean waterways are essential. Pollution, algae blooms, and habitat loss can reduce the amount of food available to them.

Favorite Foods
  • Turtle grass
  • Shoal grass
  • Seagrass
  • Algae
  • Hyacinth
  • Wetland plants
  • Other aquatic vegetation

What Is Reproduction Like for Manatees?

Pregnancies for manatees last approximately 12 months. The babies are about 66 pounds at birth. They are weaned by their mothers for the first 12 to 18 months of their lives.

These sea cows are on average 13 feet long and 1300 pounds.

Because manatees reproduce slowly, protecting mothers and calves is especially important. A healthy calf represents an important step toward a stronger future population.

Why Is the Population of Manatees Declining?

The manatees' population is declining because they are being hunted for their meat. Their habitats are getting destroyed by boating and pollution. The reproduction rates for manatees are lower than ever.

Biggest Threats to Manatees

  • Boat strikes
  • Pollution
  • Seagrass loss
  • Habitat destruction
  • Discarded fishing line and litter
  • Slow reproduction rates
