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 .
Amphisbaenids are legless, worm-like reptiles with elongated bodies nearly uniform in diameter. They are covered with ring-like scales similar in appearance to earthworms. They are underground animals, hence the eyes have degenerated to tiny indistinct spots under the rings.
Amphisbaena caeca is pinkish-brown on the head and tail with many dark spots on the annuli (body rings) of which there are between 214 and 237 in this species. It measures 10 inches (260 millimeters) in snout to vent length (SVL). Because it is somewhat difficult to distinguish its head from its tail, it is sometimes referred to as a "two-headed snake" (in Puerto Rico culebra de dos cabezas) by local people. According to folklore, wearing a live Amphisbaena on the body "helps safeguard pregnancy" while wearing a dead snake "helps rheumatism".
They can be found burrowing in the ground under logs, rocks, old tree stumps, and under termite and ant nests.
They are found in Puerto Rico, Isla Vieques, Isla Culebra, and the Virgin Islands. [2]
Amphisbaenia is a group of usually legless squamates, comprising over 180 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. Although superficially similar to the snakes and blind lizards, recent phylogenetic studies suggest that they are most closely related to the true lizards. Amphisbaenians are widely distributed, occurring in North America, Europe, Africa, South America, Western Asia and the Caribbean. They are not found east of the Caspian Sea. Most species are less than 6 inches (150 mm) long.
The Amphisbaenidae, common name worm lizards, are a family of amphisbaenians, a group of limbless vertebrates.
Anolis roosevelti, also known commonly as Roosevelt's giant anole or the Culebra Island giant anole, is an extremely rare or possibly extinct species of lizard of the genus Anolis in the family Dactyloidae. The species is native to the Antilles.
The Iberian worm lizard, Mediterranean worm lizard, or European worm lizard is a species of reptile in the family Blanidae of the clade Amphisbaenia. There are 130 species of amphisbaenians, most found in Spain, Africa, South Africa, and the Caribbean islands. 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.
Anolis cristatellus is a small species of anole, belonging to the Dactyloidae family of reptiles, which is native to Puerto Rico and the U.S. and British Virgin Islands, with introduced populations in locations around the Caribbean. The males of A. cristatellus are easily recognizable by the fin running down the top of the tail, which is known as a "caudal crest". The females also have these crests, but these are smaller than those of the males. It is often quite common in many areas on Puerto Rico, where it can be seen during the day passing the time on the lower parts of tree trunks, or on fences and the walls of buildings in urban areas, sometimes venturing down onto the ground in order to lay eggs, have a snack, or do other cursorial activities. Like many anoles, this species displays the characteristic behaviour of doing push-ups as well as inflating a pizza-like flap of coloured skin on their throat, known as a dewlap, in order to show others how hip they are, and thus attract mates or intimidate rivals. The species is known locally as the lagartijo común, and in English it is sometimes called either the common anole, the crested anole, the common Puerto Rican anole, or the Puerto Rican crested anole. There are two allopatric subspecies found in different geographical areas, with slightly different coloured dewlaps and crests.
