Legless lizards (Pygopodidae) are a large family of snake-like lizards that are considered by some to be the ecological equivelants of the solid-toothed, harmless snakes, which are poorly represented in Oz but largest family elsewhere.
Some can attain almost 60 cm in length and the Common Scaly-foot has been recorded over 75 cm in length. As with all Oz lizards they are nonvenomous.
Legless lizards have evolved an elongate, limbless form more recently than snakes, therefore all retain some primitive characteristics. A combination of 2 of the following confirms it is a lizard:
1 - Broad, fleshy tongue
2 - Ear-opening behind eye
3 - Two or more rows of belly scales as per (a) above. (b) is venomous land snake
4 - Tail as long as to much longer than body
5 - If uniform body pattern present, then longitudinal (stripes versus crossbands in Oz snakes.
Only a small sample of species are included here.
