Manatee

Physical characteristics

Manatees are robust, paddle‑tailed mammals with a rounded body, forelimbs modified into flippers and a broad, flat tail. Their skin is thick and sparse-haired, and their faces have stiff whiskers (vibrissae) used to sense food and substrates. Adult sizes vary by species but they can weigh several hundred kilograms and reach lengths of several metres. Manatees breathe air at the surface and can stay submerged for several minutes when resting.

Habitat, diet and behaviour

These animals inhabit coastal shallow waters, estuaries and freshwater rivers in tropical and subtropical regions. They feed primarily on a variety of aquatic vegetation and play an important role in maintaining healthy seagrass beds. Manatees are generally solitary or found in small groups; they move slowly but can make short bursts of speed if necessary. They tolerate both salt and fresh water and often migrate seasonally to warmer areas.

History, name and relationships

The English name "manatee" derives from Spanish manatí, itself historically traced to an Arawakan or Carib word thought to mean breast, a reference to the animal's mammary glands or to how mothers carry calves. Manatees are closely related to dugongs and to several extinct sirenians such as Steller's sea cow.

Conservation and importance

Manatees face threats from boat strikes, habitat loss, entanglement in fishing gear, cold stress and harmful algal blooms. Conservation efforts include speed restrictions for boats, habitat protection, rescue and rehabilitation programs, and public education. As grazers, manatees help shape coastal plant communities and support ecological balance; they also have value for ecotourism and as charismatic species drawing attention to aquatic conservation.
