26. Dugong
Location: Warm coastal waters from East Africa to Australia, including the Red Sea, Indian Ocean, and Pacific.
The dugong is a herbivorous marine mammal, often called the “sea cow” for its habit of grazing on seagrass meadows. Dugongs are related to manatees and are similar in appearance and behavior— though the dugong’s tail is fluked like a whale’s. These mammals can stay underwater for six minutes before surfacing. They sometimes breathe by “standing” on their tail with their heads above water.
