The hemipenis is the intromittent organ of Squamata, [4] which is the second largest order of vertebrates with over 9,000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate.

The common house gecko is a tropical species, and thrives in warm, humid areas where it can crawl around on rotting wood in search of the insects it eats, as well as within urban landscapes in warm climates. The animal is very adaptable and may prey on insects and spiders, displacing other gecko species which are less robust or behaviourally ...
Like most lizards, geckos can lose their tails in defence, a process called autotomy; the predator may attack the wriggling tail, allowing the gecko to escape. [ 8 ] The largest species, Gigarcanum delcourti , is only known from a single, stuffed specimen probably collected in the 19th century found in the basement of the Natural History Museum ...
Parthenogenesis is a mode of asexual reproduction in which offspring are produced by females without the genetic contribution of a male. Among all the sexual vertebrates, the only examples of true parthenogenesis, in which all-female populations reproduce without the involvement of males, are found in squamate reptiles (snakes and lizards).

The diet of H. mabouia is varied, and includes animals such as isopods, centipedes, [6] spiders, scorpions, cockroaches, beetles, [6] moths, flies, mosquitoes, [7] snails, slugs, frogs, anoles, other geckos and blind snakes, with the most important element being Orthoptera species.

Crested geckos mating. Little is known about the wild reproductive behavior of the crested gecko. Available information has been obtained from captive animals. Females generally lay two eggs per clutch, which hatch 60–150 days after they are laid. A female crested gecko only has to mate with a male once in order to lay 2 eggs every 4–6 ...
The big-scaled dwarf gecko is extremely small in size, measuring only 0.285g as its mean mass. [3] The lizard also maintains a snout vent length, which fluctuates from 1.7-2.7 cm with an average hitting around 2.4 cm. [9] The largest of the big-scaled dwarf geckos are found in Puerto Rico, and those found in the Virgin Islands are smaller. [10]
Like many other geckos, G. mutilata is very adaptable to its surroundings, although it usually prefers woodlands, rocky areas, and human dwellings, at altitudes from sea level to 1,400 m (4,600 ft). [1] It is also very common on sand beaches in Hawaii, where it is considered an invasive species. It makes itself at home in people's houses, and ...
