Happy #ManateeAppreciationDay! Gentle and solitary, West Indian manatees, Trichechus manatus, wander through both fresh and salt water. They keep to warm regions because they have no blubber, which insulates other marine mammals living in colder climates. Manatees also lack hind limbs needed to maneuver on land; they are born in water and remain there throughout their lives. Most marine mammals eat fish or invertebrates, but manatees feed only on seagrass and other plants growing in shallow water. Grazing and resting just below the surface, these “sea cows” come up for air every few minutes.
