 Siren, the Amphibian - Waterman and Hill-Traveller's Companion
Sirens are classified as salamanders principally because taxonomists dislike creating new orders to house just one or a few species and such reclassification requires rewriting all the textbooks.
Sirens are permanently aquatic and live in shallow, weed-filled aquatic habitats like ditches, sloughs, swamps and temporary pools devoid of fish.
Sirens are generalists when it comes to feeding and can survive on a large size-range of food ranging from microscopic organisms which they filter feed to large creatures like small fish, dragonfly larvae and crayfish.

Siren intermedia is a nocturnal species, which may help it avoid being eaten by diurnal predators such as fish and wading birds.(Petranka 1998) It spends the daylight period hidden in debris on the bottom of bodies of shallow water or burrowed in the mud and vegetation.

 Research Magazine :: Spring 1992 : Scientists Urge Caution in Amphibian Alarm
Pechmann said it can be difficult to tell in individual cases whether declines in amphibian populations are occurring naturally or are the result of pollution or other changes in the animals' habitat.
He said scientists analyzing short-term data might assume an amphibian population is fluctuating because of human-caused environmental problems, when, in fact, it is declining because of natural fluctuation.
While this method doesn't work for all species of amphibians -- tree frogs, for example, climb over the drift fence -- it is effective for the four species studied for the latest research article: the marbled salamander, the mole salamander, the Eastern tiger salamander and the ornate chorus frog.

 Caudata (salamanders, newts, amphiuma, mudpuppies, waterdogs, sirens)
The tails of most caudates are obvious, being approximately of equal length to the body, however, some may possess extraordinarily long tails (Oedipina, etc.), while the tails of others may be hard to distinguish from an elongate, snake-like body (Amphiuma, etc.).
Caudates are found mainly in the cooler Northern Hemisphere, with the exception of some genera of the family Plethodontidae that inhabit tropical zones of Central and South America, and a few other unique species.
