The Mediterranean house gecko (Hemidactylus turcicus) is a species of house gecko native to the Mediterranean region, from which it has spread to many parts of the world including parts of East Africa, South America, the Caribbean, and the Southern and Southeastern United States. It is commonly referred to as the Turkish gecko[1] as represented in its Latin name and also as the moon lizard because it tends to emerge in the evening.[citation needed]
A study in Portugal found H. turcicus to be totally nocturnal, with its highest activity around 02:00.[2] It is insectivorous, rarely exceeds 15cm (5.9in) in length, has large, lidless eyes with elliptical pupils, and purple or tan-colored skin with black spots, often with stripes on the tail. Its belly or undersides are somewhat translucent. What impact this gecko has on native wildlife in the regions to which it has been introduced is unknown.[3]
In many parts of the world, the range of H. turcicus is increasing,[1] and unlike many other reptiles, it appears to be highly resistant to pesticides. The increase may be explained as a consequence of having few predators in places where it has been introduced, and also of its tendency to take shelter in the cracks and unseen areas of human homes, for example inside walls. Reliance on human habitation has thus contributed to the species' proliferation, similar to rodents. In some Eastern Mediterranean countries such as Turkey and Cyprus, harming H. turcicus is taboo due to its benign nature, and it is often kept as a house pet.
The Mediterranean gecko is a very small lizard generally measuring 10–13cm (4–5 inches) in length, with sticky toe pads, vertical pupils, and large eyes that lack eyelids.[4] Its snout is rounded, about as long as the distance between the eye and the ear opening, 1.25 to 1.3 times the diameter of the orbit; the forehead is slightly concave; the ear opening is oval, oblique, and nearly half the diameter of the eye. Body and limb sizes are moderate. The digits are variable in length, with the inner always well developed; 6 to 8 lamellae are under the inner digits, 8 to 10 are under the fourth finger, and 9 to 11 are under the fourth toe. The head has large granules anteriorly, but posteriorly has minute granules intermixed with round tubercles. The rostrum is four-sided, not twice as broad as deep, with amedial cleft above; the nostril is pierced between the rostrum, the first labial, and three nasals; it has 7 to 10 upper and 6 to 8 lower labials; the mental is large, triangular, and at least twice as long as the adjacent labials; its point is between two large chin-shields, which may be in contact behind it; a smaller chin shield on each side of the larger pair. Upper surface of body covered with minute granules intermixed with large tubercles, which are generally larger than the spaces between them, suboval and trihedral in shape, and arranged in 14 or 16 pretty, regular, longitudinal series. Abdominal scales are small, smooth, roundish-hexagonal, and imbricate. Males have a short angular series of four to 10 (exceptionally two) preanal pores. The tail is cylindrical, slightly depressed, tapering, and covered above with minute scales and a transverse series of large, keeled tubercles, and covered beneath with a series of large, transversely dilated plates. Its color is light brown or grayish above, with darker spots; many of the tubercles and the lower surfaces are white.[5] They may be completely translucent except for the spotting. Some are darker.
They often seek darkness when fleeing. They may be seen alone or in a group up to five together.
Mediterranean house geckos inhabit a wide range of habitats, in areas near human presence such as university campuses, cemeteries, coastal regions, and shrublands. In these urban or suburban areas, they are typically seen in the cracks of old brick buildings. They can also be found in other areas such as mountain cliffs and caves. Their nests can be found in trash piles, attics, or under the baseboards of buildings.[20]
Mediterranean house geckos are nocturnal.[20] They emit a distinctive, high-pitched call somewhat like a squeak or the chirp of a bird, possibly expressing a territorial message. Because of this aggressive behavior, juveniles avoid most interaction with adult geckos. They are voracious predators of moths and small roaches, and are attracted to outdoor lights in search of these prey. They are also attracted by the call of a male decorated cricket (Gryllodes supplicans); although the males are usually safely out of reach in a burrow, female crickets attracted to the male's call can be intercepted and eaten.[21]
Reproduction
Mediterranean house geckos reach sexual maturity within four months to a year. Male house geckos produce clicking sounds to attract a mate, with the females responding in their own squeaks. They also display copulatory biting, with stronger bites resulting in higher fertilization success. Fertilization is internal. The breeding season is typically from April to August each year and eggs are laid mid-May to August in an average clutch size of two. Female house geckos experience delayed fertilization and can store sperm in a funnel-shaped organ called the infundibulum for up to five months. Because of this, exact gestation time is unknown, but is estimated to be around 40 days. Neither males nor females have been observed providing any parental care, with males going as far as to bite the juveniles. [22]
Prey
Primary prey of Mediterranean house geckos has been noted to include crickets, grasshoppers, cockroaches, spiders, beetles, moths, butterflies, ants, isopods, and snails. These geckos are visual hunters; prey selection depends on whether it is alive or dead. Mediterranean house geckos are more likely to choose living prey over dead.[22]
Gekkonidae is the largest family of geckos, containing over 950 described species in 64 genera. The Gekkonidae contain many of the most widespread gecko species, including house geckos (Hemidactylus), the tokay gecko (Gekko), day geckos (Phelsuma), the mourning gecko (Lepidodactylus), and dtellas (Gehyra). Gekkonid geckos occur globally and are particularly diverse in tropical areas.
The greater earless lizard is the only species in the monotypic genus Cophosaurus. It is closely related to the smaller, lesser earless lizards and other species in the genus Holbrookia, and in fact was placed in that genus and referred to Holbrookia texana from 1852 into the 1970s. Earless lizards lack external ear openings, an adaptation to burrowing in the sand, as are the recessed lower jaw and flared upper labial scales. Greater earless lizards are sexually dimorphic, males grow larger and are more colorful than females, exhibiting pink and green colors that are particularly bright in the breeding season. Two bold black bars mark the lateral region of males but are greatly reduced and vague, or occasionally entirely absent in females.
The Mexican blind lizard is a species of legless lizard in the family Dibamidae, and the only species in the genus Anelytropsis. It is endemic to Mexico. They look like Amphisbaenia, but are in fact, only distantly related.

The Indo-Pacific gecko, also known commonly as Garnot's house gecko, the fox gecko, and the Assam greyish brown gecko, is a species of lizard in the family Gekkonidae. The species is found in India, across Southeast Asia, Australia, and throughout Polynesia. Adults are about 4 to 5 in in total length. They are seen as dark gray or brown with light markings in daylight and a pale, translucent colour at night. The belly is orange or yellow. The head has a long, narrow snout, hence the name fox gecko. The flattened tail has a row of spiny scales on the lateral edges. The species is parthenogenic – all individuals are female and lay eggs that hatch without requiring male fertilisation.

Ctenosaura acanthura, is a species of iguanid lizard found in eastern Mexico and extreme western Guatemala. The standardized English name is the Mexican spiny-tailed iguana. Confusingly however, an earlier edition of standardized names for Mexican herpetofauna called Ctenosaura acanthura the northeastern spinytailed iguana and applied the name Mexican spinytailed iguana to Ctenosaura pectinata, which was called the western spiny-tailed iguana in the second edition. It has also been referred to as the Veracruz spiny-tailed iguana and Gulf Coast spiny-tailed iguana. It is an egg laying species that is mostly herbivorous and a moderately large lizard commonly growing over one meter in total length.
