Snakes, lizards and Amphisbaenia are closely related and belong to a single order, Squamata, with three suborders.
In spite of the theory regarding the evolution of modern snakes from burrowing lizards, there is no modern lizardfamily that could be construed to be a link between lizards and snakes.
Even the legless amphisbaenians (suborder Amphisbaenia), which were at one time thought to be lizards “turning into snakes,” have now been classified into their own suborder.

This file contains a systematic overview of Amphisbaenidae, featuring links to books, other pages on the web about Amphisbaenidae, pictures etc. Common names in different languages may be also available as well as a short dutch description to the taxon.
In contrast to other limbless lizards or snakes, which have a reduced left lung, the right lung of amphisbaenians is reduced in size.

Anops kingii is a member of Amphisbaenia, a lineage (160 species) of mostly limbless burrowing squamates.
The specimen was scanned by Richard Ketcham on 11 February 2003 obliquely along the coronal axis for a total of 663 slices, each slice 0.0192 mm thick with an interslice spacing of 0.0192 mm.
Systematics and evolution of the Amphisbaenia (Reptilia: Squamata) based on morphological evidence from fossil and living forms.
In this paper, a phylogenetic study of the Amphisbaenia is presented based on morphological characters investigated in living and fossil forms.
The basal positions of Bipes and Blanus imply that a round-headed cranial shape is the primitive condition for Amphisbaenia in contrast to some previous hypotheses.
In this analysis, amphisbaenians are nested within Squamata, in contrast to a hypothesized relationship as the sister-group to the remainder of squamates (alone, with snakes, or with another group of limbless burrowing lizards, Dibamidae).

Although Amphisbaenia eggs have been found in ant nests, it remains disputable whether this is an obligatory or even a preferable location for egg-laying.
The general pattern of reproductive output in Amphisbaenia is characterized by a low number of eggs/embryos per clutch whose individual size is comparatively large in relation to adult body size.
Eggs are markedly elongated on the long axis and arranged in-line within the abdominal cavity possibly to prevent/diminish biomechanic drawbacks of egg bearing.

The HRXCT data (available at www.digimorph.org) corroborate and extend previous hypotheses that the mechanical organization of the head in Rhineura is organized to a large degree around its burrowing lifestyle.
Rhineura is a member of Amphisbaenia, a lineage (160 species) of mostly limbless burrowing squamates.

Kearney's dissertation research involves a higher-level phylogenetic analysis of the Order Amphisbaenia, a group of highly specialized, limbless, burrowing reptiles that spend their entire life in underground tunnels.
Osteological characters will be examined from fossil and Recent forms primarily to: (i) identify monophyletic taxa within Amphisbaenia; and (ii) ascertain patterns and directions of divergence in morphological characters.
Support for training of graduate students in modern technologies is critical to maintain the workforce of scientists capable of addressing questions and issues in global biology.
Females give off a scent in their feces to communicate that they are ready to mate and the male replies by rubbing his chin on her and licking her body.
A normal adult Komodo dragon diet consists mainly of carrion, but it is not uncommon for them to attack and eat a variety of large prey, including goats, pigs, deer, wild boar, horses, water buffalo, and smaller Komodo dragons.
A real animal that takes its name from the amphisbaena, the amphisbaenia, is a "worm lizard" native to South America and parts of Africa, the Middle East, and Mediterranean Europe.
The amphisbaenia is similar in color and appearance to a worm, but is actually a relative of lizards and snakes.
Like its mythical cousin, the amphisbaenia can slither equally well in either direction, and its head and tail are difficult to distinguish at a glance.

Most species have no limbs and move by undulating the scales of their loose-fitting skin, but a few Mexican forms (genus Bipes) do have forelimbs.
More than 100 species of worm lizards are classified in many genera making up the two families--Amphisbaenidae and Trogonophidae--in a suborder (Amphisbaenia) separate from all other lizards.
Worm lizards, or amphisbaenids, are found in the Americas, Europe, and Africa.
The Amphisbaenia are an extant order of elongate, limbless, fossorial reptiles that inhabit equatorial regions.
The fossil record of the North American Amphisbaenia extends from the Paleocene to the Pleistocene, with the greatest abundance in the Eocene to Oligocene continental deposits of northern Colorado, western Nebraska, southern South Dakota and Wyoming.
The trace fossil record of these burrowing reptiles, however, is unknown.
The Amphisbaenia is a successful group of some 140 species of strange, specialized burrowing reptiles with reduced eyes and limbs, found mainly in parts of Africa and America.
However, appropriate embryonic material available for the first time shows that it is a membrane bone.
This remarkable condition tends to emphasize the distinct status of the Amphisbaenia within the Squamata, as a sister-group equivalent to the lizards or the snakes
