Amphisbaenia is a group of typically legless lizards, comprising over 200 extant species. Amphisbaenians are characterized by their long bodies, the reduction or loss of the limbs, and rudimentary eyes. As many species have a pink body and scales arranged in rings, they have a superficial resemblance to earthworms. While the genus Bipes retains forelimbs, all other genera are limbless. Phylogenetic studies suggest that they are nested within Lacertoidea, closely related to the lizard family Lacertidae. Amphisbaenians are widely distributed, occurring in North America, Europe, Africa, South America, Western Asia and the Caribbean. Most species are less than 6 inches (15 cm) long.
The Aniliidae are a monotypic family created for the monotypic genus Anilius that contains the single species Anilius scytale. Common names include the American pipe snake and false coral snake. It is found in South America. This snake possesses a vestigial pelvic girdle that is visible as a pair of cloacal spurs. It is ovoviviparous. It is non-venomous, and its diet consists mainly of amphibians and other reptiles. Two subspecies are recognized, including the nominate subspecies described here.
Robert Friedrich Wilhelm Mertens was a German herpetologist. Several taxa of reptiles are named after him. He postulated Mertensian mimicry.
Amphisbaena caeca, commonly known as the Puerto Rican worm lizard or blind worm lizard, is a species of worm lizard endemic to Puerto Rico. These animals are vermicular reptiles that live under logs, rocks, and dirt. Other species of Amphisbaenids in the Caribbean include Amphisbaena bakeri, Amphisbaena fenestrata, Amphisbaena schmidti, Amphisbaena xera, and Cadea blanoides.
The Iberian worm lizard, Mediterranean worm lizard, or European worm lizard is a species of reptile in the family Blanidae of the clade Amphisbaenia. The Iberian worm lizard is locally known as cobra-cega (Portuguese), culebrilla ciega (Spanish), and colobreta cega (Catalan), all meaning "blind snake". Recent studies into the mitochondrial and nuclear genomic data of 47 isolated B. cinereus populations show rather large sequence divergence between two apparent clades, leading some researchers to call for a division of the Iberian worm lizard into two species. While little is known of B. cinereus in comparison with some other reptile species, new insight is growing about this primitive, ancestral reptile.
Amphisbaena is a genus in the family Amphisbaenidae, commonly known as worm lizards. Over 100 species are placed in this diverse genus.
Amphisbaena alba, also known as the red worm lizard or less commonly as the white or white-bellied worm lizard, is a species of amphisbaenian in the reptilian order Squamata. Despite the large geographic range that this species covers, little is known about its ecology due to its secretive habits. A. alba has a diverse diet ranging from plant material to small vertebrates. Numerically, beetles, ants, and spiders compose the majority of their diet; however, ants, insect larvae, beetles, cockroaches, hemipterans, mole crickets, crickets, grasshoppers, termites, spiders, scorpions, pseudoscorpions, and annelids are ingested to satisfy a larger volume. The females are somewhat larger than the males, and can reach over 80 cm, which is quite large for an amphisbaenian. They are known to bury themselves in leafcutter ant nests and hide in the ants' garbage dump areas to avoid irritating the ants into attacking, and to bury themselves to avoid predation in general.
Darwin's ringed worm lizard is a species of amphisbaenian in the family Amphisbaenidae. It is endemic to South America.
The Carvalho worm lizard, also known commonly as Carvalho's worm lizard, is a species of worm lizard in the family Amphisbaenidae. The species is endemic to Brazil.
Amphisbaena ridleyi, known by the common names Ridley's worm lizard or the Noronha worm lizard, is a species of amphisbaenian in the family Amphisbaenidae. The species is endemic to the island of Fernando de Noronha off the coast of Brazil. It is one of two indigenous reptiles on the island.
Amphisbaena mertensii, also known as the Mertens' worm lizard or Mertens's worm lizard, is a species of worm lizard in the family Amphisbaenidae. The species is endemic to South America.
Amphisbaena xera, known commonly as the dry worm lizard, Puerto Rican dryland worm lizard, or the North American worm lizard, is a worm lizard species. It is endemic to Puerto Rico.
Loveridgea is a genus of amphisbaenians in the family Amphisbaenidae. Species in the genus are commonly known as worm lizards, even though they are not lizards. Two species are placed in this genus.
The Cuban worm lizard is a worm lizard species in the family Amphisbaenidae. It is endemic to Cuba.
