What does sirenian mean?
A sirenian is a member of Sirenia, the mammalian order that includes manatees and dugongs. These animals are primarily aquatic, and many inhabit rivers, estuaries, coastal waters, and shallow seas. Although they live much of their lives in water, sirenians breathe air, give birth to live young, and nurse them with milk. Most feed on aquatic vegetation, although the diets of some dugongs include seagrass and other marine plants. The word is used mainly in zoology, wildlife conservation, and environmental science; when discussing an individual animal in ordinary speech, “manatee” or “dugong” is generally more accessible. As an adjective, “sirianian” identifies the mammals themselves, their biological characteristics, or research and conservation concerning them. The name derives from the taxonomic group Sirenia, itself associated with the siren of Greek mythology, traditionally depicted as a dangerous or enchanting marine creature.

"Scientists monitored the sirenian population by drone survey and acoustic detection."
The adjective is normally used in scientific, conservation, or ecological contexts.
In taxonomic usage, members of the order are collectively called Sirenia; the plural “sirenians” is also used in general writing.

Where does sirenian come from?
The word was formed from New Latin Sirenia, the name of the mammalian order containing manatees and dugongs. Sirenia in turn derives from Latin siren, which continues Greek seirēn, the term for the mythological sirens. The mythological association reflects the traditional belief that these creatures lured sailors with their songs, although the connection was applied to the animals through their taxonomic name.
How sirenian is actually used
The term is chiefly scientific and zoological. In general reference works, the more familiar names “manatee” and “dugong” are usually preferred when identifying particular species.
