Burton's legless lizard (Lialis burtonis) is a species of lizard in the family Pygopodidae. The species lacks forelegs and has only rudimentary hind legs. Pygopodid lizards are also referred to as "legless lizards", "flap-footed lizards" and "snake-lizards". This species is native to Australia and Papua New Guinea.
English zoologist John Edward Gray described Burton's legless lizard in 1835. The specific name, burtonis, is in honour of British army surgeon Edward Burton (1790–1867). Burton's legless lizard (Lialis burtonis) is a member of the genus Lialis within the family Pygopodidae. There are approximately 40 species in the family Pygopodidae, however, Burton's legless lizard and another species (L. jicari) are the only species that fall within genus Lialis. Members in genus Lialis are considered analogous to macrostomatan snakes as these taxonomic groups have functionally similar adaptations such as the ability to swallow relatively large prey whole. However, their resemblance to snakes is merely superficial example of convergent evolution, and they are not closely related.
Differences between legless lizards and snakes include the lack of venom glands in legless... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Burton's Legless Lizard is recorded against all the reptiles logged in Perth (42 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
