Anniella alexanderae, also known as the temblor legless lizard, is a species of legless lizard found in California, [1]
The family Anniellidae, known as American legless lizards, contains six species in a single genus Anniella: A. pulchra, the California legless lizard, the rare A. geronimensis, Baja California legless lizard, and four more discovered in 2013.
Pygopodidae, commonly known as legless lizards, snake-lizards, or flap-footed lizards, is a family of squamates with reduced or absent limbs, and are a type of gecko. At least 35 species are placed in two subfamilies and eight genera. They have unusually long, slender bodies, giving them a strong resemblance to snakes. Like snakes and most geckos, they have no eyelids, but unlike snakes, they have external ear holes and flat, unforked tongues. They are native to Australia and New Guinea.
Delma is a genus of lizards in the family Pygopodidae. The genus Delma contains 22 valid described species, all of which are endemic to Australia.
The Chamaesaura, also known as grass lizards, are a genus of legless lizards from southern and eastern Africa. The limbs are reduced to small spikes. Chamaesaura propel themselves like snakes, pushing against contact points in the environment, such as rocks, plants and irregularities in the soil. They are viviparous and eat small invertebrates, especially grasshoppers.
Typhlosaurus is a genus of African lizards, one of a number of genera of limbless lizards in the skink family (Scincidae). This group was recently revised with most species formerly attributed to Typhlosaurus now placed in Acontias. The current definition of Typhlosaurus includes five attenuate body legless lizards from southwestern Africa. This is the sister genus to Acontias, which together form the well supported Afrotropical subfamily Acontinae.
Many vertebrates have evolved limbless, limb-reduced, or apodous forms. Reptiles have on a number of occasions evolved into limbless forms – snakes, amphisbaenia, and legless lizards. The same is true of amphibians – caecilians, Sirenidae, Amphiumidae and at least three extinct groups. Larval amphibians, tadpoles, are also often limbless.
Legless lizard may refer to any of several groups of lizards that have independently lost limbs or reduced them to the point of being of no use in locomotion. It is the common name for the family Pygopodidae,. These lizards are often distinguishable from snakes on the basis of one or more of the following characteristics: possessing eyelids, possessing external ear openings, lack of broad belly scales, notched rather than forked tongue, having two more-or-less-equal lungs, and/or having a very long tail.
The striped legless lizard is a species of lizards in the Pygopodidae family endemic to Australia. As of 2015 it is threatened with extinction, with few habitats left.
Burton's legless lizard 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.
Platynota is a polyphyletic group of anguimorph lizards and thus belongs to the order Squamata of the class Reptilia. Since it was named in 1839, it has included several groups, including monitor lizards, snakes, mosasaurs, and helodermatids. Its taxonomic use still varies, as it is sometimes considered equivalent to the group Varanoidea and other times viewed as a distinct group. It is phylogenetically defined as a clade containing Varanidae. It also includes many extinct species.
Anniella pulchra, the California legless lizard, is a limbless, burrowing lizard often mistaken for a snake.
Gekkonomorpha is a clade of lizards that includes geckos and their closest relatives. Although it was first named in 1900, Gekkonomorpha was not widely used as a formal taxon until it was given a phylogenetic definition in the 1990s. Under this definition, Gekkonomorpha is a stem-based taxon containing the node-based taxon Gekkota, the group that includes the last common ancestor of all living geckos and its descendants. The extent of Gekkonomorpha beyond gekkotans differs between studies. For example, Lee (1998) defined Gekkonomorpha in such a way that it included not only Gekkota but the legless amphisbaenian and dibamid lizards as well. The phylogenetic analysis of Conrad (2008), which did not support a close relationship between geckos and legless lizards, used Gekkonomorpha in a much more restrictive sense so that it included only Gekkota and a few extinct lizards more closely related to Gekkota than to any other living group of lizards. Some of the most recent phylogenetic analyses suggest that the extinct lizards Gobekko and Parviraptor may be stem gekkotans, although other analyses find that Gobekko may instead be within Gekkota and Parviraptor outside Gekkonomorpha.
Isla San Jerónimo, is an island in the Pacific Ocean on the west side of the Baja California Peninsula. The island is part of the large Ensenada Municipality and accessed from Punta Baja near the community of El Rosario, Baja California.
Isla San Martín is an island in the Pacific Ocean west of the Baja California Peninsula. The island is uninhabited and is part of the Ensenada Municipality.
Anniella stebbinsi, the Southern California legless lizard, is a small, slender lizard, and, as the name suggests, is legless. Not much is known about the Southern California legless lizard as a separate species, with most observations conducted while it was not recognised as separate from Anniella pulchra.
Anniella campi, also known as the Southern Sierra legless lizard is a species of legless lizard found in California, specifically in the Sierra Nevada It was previously known as Anniella pulchra. It has double dark lateral stripes.
Anniella geronimensis, also known as the Baja California legless lizard, is a species of legless lizard found in Mexico.
Anniella grinnelli, also known as the Bakersfield legless lizard, is a species of legless lizard found in California,
