	Sirenidae
		Salamanders of the family Sirenidae do not metamorphose and retain the appearance of an aquatic larva throughout life.
		Metamorphosis is absent in the Sirenidae, leading to a number of paedomorphic characteristics in adults.
		The salamander family Sirenidae is the sole member of the caudate suborder Sirenoidea.

		The best current hypothesis of salamander family relationships based upon molecular and morphological data (Larson and Dimmick, 1993) places the Sirenidae as the sister taxon to all remaining salamanders.
		The Sirenidae therefore appears to represent an ancient lineage that has no close phylogenetic relatives among extant organisms.'; TEXTNOTE REFINDENT ID=1003 TITLE=References TEXT='Duellman, W. and L. Trueb.
		Absence of characteristics found in other salamanders is noted where it is important for distinguishing sirens from other salamanders and/or determining their relationships to other salamanders.

	Reptiles & Amphibians
		With an evolution span of around 130 million years the amazing mud siren is found in the Sirenidae family and the Caudata order.
		One of the two genera in this family, Sirenidae lacertina which are the great sirens and Pseudobranchus which are the mud sirens, the mud siren is different in that it has only one set of gills and three minute fingers on the hands of its front legs.
		This could create a problem for the mud siren hunter when he comes face to face with the greater siren which is known to measure over thirty inches in length.

	SIRENIDAE - Sirens
		Indiviglio recommends a shallow aquarium for sirens so that they can rise to the surface for air without having to swim: some cover in the form of branches and aquatic plants would also seem to be a good idea.
		There seems to be no one single work (at least outside academic circles) dealing with the family Sirenidae in its entirety.
		However, there is information both in print and on the Internet on the individual species and genera, both natural history and captive husbandry, but less than for many of the other Caudata families.

		Salamanders are distinguished from other amphibians (frogs and caecilians) most obviously by the presence of a tail in all larvae, juveniles and adults, and by having limbs set at right angles to the body with forelimbs and hindlimbs of approximately equal size (except in the family Sirenidae, which lacks hindlimbs).
		Because the arrangement shown here is the most parsimonious tree resulting from combined analysis of 209 molecular and morphological characters, it is recommended as the best current working hypothesis.
		The phylogeny presented here indicates strongly that the salamanders that retain at least some aquatic larval characteristics throughout life (families Amphiumidae, Cryptobranchidae, Proteidae, Sirenidae and parts of the Ambystomatidae and Plethodontidae) do not form a monophyletic group.
