6 days ago · dugong, (Dugong dugon), marine mammal that inhabits the warm coastal waters of the Indian and Pacific Oceans, feeds on seagrasses, and is similar to the manatee.
The dugong (/ ˈd (j) uːɡɒŋ /; Dugong dugon) is a marine mammal. It is one of four living species of the order Sirenia, which also includes three species of manatees.

Dugongs are easily distinguished from manatee species by their dolphin-like tail, whereas manatees have hind fins more similar to a seal or walrus. They also have other specific adaptations such as a down-turned snout that allow it to feed specifically on seagrass with its unique, peg-like molar teeth.
Much like they move, dugongs also grow slowly. Females give birth to just one calf after a year-long pregnancy. Her young will remain close to her for up to 18 months. Because of their long life span (70 years) and slow reproduction rates, dugong populations are vulnerable despite legal protection. Humans have hunted dugongs for thousands of years,...
Dugongs have poor eyesight but good hearing. They are also covered head to tail with short hairs. These hairs are most concentrated around the mouth and are thought to help them navigate the seagrass beds, much like dogs and cats use their whiskers as a navigational aid.
Dugong bones have almost no bone marrow inside and are very solid. In fact, dugong bones are among the densest in the entire animal kingdom. These may act as a type of ballast, allowing the animal to remain effortlessly suspended just below the surface of the water when resting. Sometimes, they will rest their tail on the bottom to anchor themselve...
Although adult dugongs have few predators due to their size, they are quite susceptible to pathogens including helminths, cryptosporidium, and other bacterial and parasitic infections. In fact, in Queensland, Australia, up to 30% of dugong deaths are due to disease. Even still, the biggest threat to dugongs is habitat loss and death at the hands of...

Dugongs belong to the order Sirenia, so named for the mammary glands akin to human breasts and their nursing behavior. Because of this, some sailors call dugongs mermaids or sirens, from which the name was created.
