Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (Gekko gecko) are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened ...
Lizard scales may differ strongly in form on different parts of the lizard and are often of use in taxonomy to differentiate species (or higher taxa, such as families). For instance, members of the family Lacertidae have large head plates (Figure 2) while geckos have no such "plates" but only very small head scales.
A Mediterranean house gecko in ambush on a nest of a sphecid wasp Sceliphron spirifex. Mediterranean house geckos are nocturnal. [21] 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 ...
The majority of lizard species are active during the day, [28] though some are active at night, notably geckos. As ectotherms , lizards have a limited ability to regulate their body temperature, and must seek out and bask in sunlight to gain enough heat to become fully active. [ 29 ]
The common house gecko (Hemidactylus frenatus) is a gecko native to South and Southeast Asia as well as Near Oceania. It is also known as the Asian house gecko, Pacific house gecko, wall gecko, house lizard, tiktiki, chipkali [3] or moon lizard. These geckos are nocturnal; hiding during the day and foraging for insects at night.
Gekkonidae (the common geckos) is the largest family of geckos, containing over 950 described species in 62 genera. [1] [2] ...
Currently there are about 40 extant families of Lacertilia.These vary considerably, e.g. in shades, colours, and sizes. For example, the largest representative among Geckos, the New Caledonian giant gecko (Rhacodactylus leachianus), has a length of up to 36 cm (14 in), while the largest species in the family Varanidae, Komodo dragon (Varanus komodoensis), has a length up to 3 metres (10 ft ...
Many lizards exhibit an ability to alter the hue and/or intensity of skin color (chameleons are the extreme example), and New Caledonian Geckos are no exception. This phenomenon is facilitated by pigment-containing cells called chromatophores. This is a form of camouflage and can help the gecko blend into their environments.
