age variability and sexual dimorphism
sexual dimorphism in squeaky gecko is shown in larger size of females compared with males.In females anal pores are less developed and can almost completely with age abyss.Some of the proportions of the body are also subject to age variability.Juveniles of this species over short-tailed.In young animals the eye diameter greater than the length of the body.The values of these indices of mature individuals become more homogeneous.
squeaky gecko is common in Kazakhstan and Central Asia.Outside of our country - in southern Mongolia, northern Afghanistan, northeastern Iran and further to Northern China.
Habitat
squeaky gecko (photo of this lizard may be possible to consider carefully in the article) - a typical inhabitant of semi-desert, sometimes penetrating deep into the wilderness, where adheres to all parts of the semi-desert type.Mostly found along the slopes of a small hill, which are covered with fine and macrofragmental soil, and sometimes - in the gravelly-clay plains.
known cases of penetration of the animal on the outskirts of the sand.For all its habitats characterized by sparse vegetation, which consists of tasbiyurguna, boyalycha, wormwood, Eurotia, low-growing grasses and thistles.It settled under the slabs of limestone cliffs on for almost bare gravelly-clay plains, as well as on the outskirts of the thickets of saxaul.
Behavior
gecko shelters are burrowing animal holes, cracks and crevices in the ground, the space under the rocks, hollows and cavities in the root of the saxaul.By nightfall animal out of hiding, but in cloudy weather it can be seen during the day.It may make the metal a prolonged squeak that day is easy to confuse with the voice of a bird.Hibernation in October.He spends the night in search of food near his refuge.
interesting feature of these lizards is their very loud "singing", as well as a huge range of different sounds that accompany them at all times of life: croak, chirp, clicks, squeaks.
squeaky gecko (interesting facts about his life are shown in this article) moves during the activity short dashes, bending and lifting high the trunk.Can easily move on vertical surfaces, but they are, however, avoided.It does not go far from their hiding places.They hunt at the entrance holes and crevices for insects under rocks and run one after the other.In the summer the animals are havens space under the slabs and stones of emptiness haloxylon, cracks in the soil, cracks stone artificial structures, vertebrate burrows.They hibernate in crevices, holes.
Activity
squeaky gecko, a photo which shows it in all its glory, is active at temperatures up to 25 ° C.During the day they hide in a safe haven.It is noted in cloudy weather on the surface.
squeaky gecko feeds primarily on insects, among them is dominated by butterfly caterpillars, small beetles, orthoptera, bugs, Diptera, leafhoppers, spiders, ants, and scorpions phalanx.In the stomachs of animals dominated by the frequency of occurrence of beetles, spiders, caterpillars and butterflies, bugs and ants.
Reproduction
gecko reach sexual maturity at a total body length up to 28 millimeters.In collections of the sex ratio approximated by 1/1.Mating takes place in late April.In late May, egg laying begins and lasts until the end of June.During this period the female lays several times by one, sometimes two eggs with an average size 6 X 9 mm.Since July, juveniles begin to appear.In dvadtsatimesyachnom age comes sexual maturity, in other words, the second spring after the birth.
Growth rates
Cubs, newly hatched from eggs, have a length of the body about 18 mm.By the end of the season they are active (no tail) reach a size of 24 mm, which means that the first generation individuals can take part in an active breeding the next year.This species is characterized by a population of 4 age groups, the eldest of them at the same time includes representatives of three years and older.
reasons for downsizing
squeaky gecko has a few enemies.Among them are the magpie.Also, the reason for reducing the number of lizards is the shrinking of the Aral Sea, which led to a retreat from the shoreline rocks for several kilometers.This, in turn, has caused a sharp reduction in the number of invertebrates.In addition, it should be noted that the gecko habitats are displaced from their land during plowing.
Similar species
squeaky gecko from Brigandine characterized in that on the surface of the body bumps do not create longitudinal rows, and the presence of tubercles - from smooth.
protection and practical significance
animal is very useful views.Typically, it takes lots that are not used by man.But there are exceptions: for example, The Big Bogdo animal habitats are destroyed by generating bedrock, which is used to produce gravel.
should be noted that in this area needs protection measures squeaky gecko.The Red Book has included it in its list.This need is due to a decrease in their numbers here and the uniqueness of this type of herpetofauna for our country.
