Sirenia (commonly referred to as sea cows) is an order of fully aquatic, herbivorous mammals that inhabit swamps, rivers, estuaries, marine wetlands, and coastal marine waters. Four species are living, in two families and genera.
Order Sirenia
Manatees (1)
The Sirenia order consists of four species in two families, manatees and dugongs. They are also known as sea cows. Members of this order live their entire lives in the water and live primarily on vegetation.

The Greater Siren, Siren lacertina, is found in calm, hyacinth-covered lakes and slow-moving rivers and canals throughout the state. It is gray green or brown with lighter flecks along the sides.
Sirenians are slow and passive mammals of tropical and sub-tropical waters. Their large thick bodies betray their heritage as relatives of elephants.
Siren lacertina
At more than three feet in length, the greater siren is the largest of the sirens, amphibians with eel-like bodies and no hind limbs.
The Sirenia are large, plump, torpedo-shaped mammals adapted to an aquatic habitat; they live in the bays and coastal waters in tropical regions of the world.
Greater sirens often have greenish-yellow dots.

Western Lesser Siren (Siren intermedia nettingi)
Description: A long, eel like salamander with bushy external gills, a flattened tail, and tiny front legs (and no hind legs). Color is gray, brown, or olive. Adults are 7 to 19.
There are four siren species and various subspecies, distinguished by geographic range, coloring, and size. The western lesser siren is confined to the southern and central United States.

Sirens have no hind legs. This fact and some other features of sirens make some scientists think they are not salamanders at all, but amphibians set apart from all others. Whatever they may be, sirens certainly are different.
Sirenia - dugongs and manatees
These mammals are adapted to spend all of their time in water. They have flippers for front limbs and a flat tail. They have thick bristles on their lips. They are herbivores and eat aquatic vegetation.

All species of sirenians are protected to some extent by national or local acts in every country they inhabit.
Like all modern sirenians, the dugong has a fusiform body with no dorsal fin or hind limbs, instead possessing paddle-like forelimbs used to maneuver itself.

The American Manatee (Trichechus manatus) is a water-dwelling mammal nicknamed "sea cow" because they graze on underwater plants like land cows. They belong to the Sirenia family, named after the Sirens of ancient myth.
Although superficially they resemble whales, sirenians have evolved independently. They are thought to be descended from the group of ancient land mammals that also gave rise to the elephants.

FEEDING HABITS: Adult mud snakes feed almost entirely on amphiumas and sirens. The presence and abundance of these chief components of the mud snake's diet are required for mud snakes to survive.

Behavior/Adaptations
Gibbons are monogamous.
Early morning vocalizations consist of eerie howls and siren-like crescendos.
Primarily diurnal and are almost exclusively arboreal. Can walk bipedally for short distances.
They include the cetaceans (whales and dolphins), pinnipeds (seals, sea lions, and walrus), sirenians (manatees and dugongs), sea otters, and even the polar bear.
Some believe that dugongs were the inspiration for ancient seafaring tales of mermaids and sirens.

Prey items for Western Mud Snakes include sirens, frogs, fish, and of course, their favorite food: an eel-like amphibian called an amphiuma. Adults average three to four feet long, but the state record is just over six feet.
MANATEE
Manatees are gentle, slow-swimming, aquatic mammals. They are not whales (order Cetacea), but belong to the order Sirenia.
The first evidence of nearby coyotes is often the high-pitched "yip-yip-yihwool" calls they make in late evening and near day break. The calls may be spontaneous, but they usually follow a siren, train whistle or other loud sound.
Aquatic forms include the Congo eel (measuring up to 3 ft. long) this siren (this up to 30 in. long) also mud puppy all of these retain their gills throughout life, in the underground streams the pale yellow salamanders are blind.
Almost all involve species within a single genus (e.g., any of the 8 species of pangolin in genus Manis) but I did expand the concept to include "any sirenid" as a single pick: these are the 3 species of manatee plus the South Pacific dugong.
The head is not much wider than the neck, and the scales are smooth. A spine on the tip of the tail is used to subdue slippery prey, primarily large, aquatic salamanders (e.g., sirens and amphiumas).
Mud snakes spend the winters buried in soil and mud until the warmer weather returns. They eat tadpoles, frogs, and fish--but their favorite food is a small eel-like salamander called a siren.
Nor is the aardvark closely related to the South American anteater, despite sharing some characteristics and a superficial resemblance. The closest living relatives of the aardvark are the elephant shrews, along with the sirenians, hyraxes, tenrecs, ...
More often heard than seen, they give various "Yip, yip" cries, and often maniacal barks and howls. One or two may sound like a dozen. In the city, they are often heard serenading a fire, police or ambulance siren.
