Dugongs (Dugong dugong) are closely related to manatees and are the fourth species under the order sirenia. Unlike manatees, dugongs have a fluked tail, similar to a whale’s, and a large snout with an upper lip that protrudes over their mouth and bristles instead of whiskers.
What is the order of Sirenia?
Therapsid
Sea cows/Order
What animals belong to the order Sirenia?
The Sirenia currently comprise two distinct families: Dugongidae (the dugong and the now extinct Steller’s sea cow) and Trichechidae (manatees namely the Amazonian manatee, West Indian manatee, and West African manatee) with a total of four species.
What is the closest relative of manatees and dugongs?
4. Dugongs are sirenians and therefore related to manatees. Though they resemble cetaceans (whales, dolphins and porpoises), dugongs and manatees are believed to be descendants of land mammals that make them more closely related to elephants than whales.
Which is bigger a dugong or manatee?
#2 Body size – Manatees can grow up to 4 metres/13 feet long, whereas dugongs rarely get larger than 3 metres/9.8 feet long. Manatees have a paddle-shaped tail. Fun fact: When dugongs surface to breathe, they sometimes “stand” on their tail with their head above water.
What order is the dugong in?

How are sirenians related to elephants?
Sirenians, proboscideans (which includes elephants, mastodons and woolly mammoths) and embrithopods (an extinct group of animals that looked a bit like rhinos, though they aren’t close relatives) are all thought to have descended from a common ancestor. Together these groups belong to another group called Tethytheria.
How did the manatees evolve?
Manatees trace their evolutionary lineage to grass-eating land mammals that lived at least 50 million years ago. Their oldest ancestors were pig-like, four-legged animals that looked, improbably, like a cross between a hippopotamus and an otter, as one scientist has described it. Manatees also never chased prey.
What is Adugong?
The dugong is a species of sea cow found throughout the warm latitudes of the Indian and western Pacific Oceans. It is the only member of the Dugongidae family, and its closest living relatives are the manatees. The dugong, like all sea cows, is herbivorous.
What is the difference between a dugong and a manatee?
The dugong is easily distinguished from the manatees by its fluked, dolphin-like tail, but also possesses a unique skull and teeth. Its snout is sharply downturned, an adaptation for feeding in benthic seagrass communities. The molar teeth are simple and peg-like unlike the more elaborate molar dentition of manatees.
What is Sargasso Sea algae?
While there are many different types of algae found floating in the ocean all around world, the Sargasso Sea is unique in that it harbors species of sargassum that are ‘holopelagi’ – this means that the algae not only freely floats around the ocean, but it reproduces vegetatively on the high seas.
Is the Sargasso Sea holopelagic?
While there are many different types of algae found floating in the ocean all around world, the Sargasso Sea is unique in that it harbors species of sargassum that are ‘holopelagic’ — this means that the algae not only freely floats around the ocean, but it reproduces vegetatively on the high seas.
How much seagrass can a dugong eat per day?
They can eat up to 40 kilograms of seagrasses per day. Dugongs are seagrass community specialists and their range is broadly coincident with the distribution of seagrasses in the tropical and sub-tropical Indo-West Pacific.
