Description
The adults catch up dimensions from the 15 to the 30cm. Like nella greater part goddesses straight them, they are the females to catch up greater dimensions, while the males very rarely exceed the 18cm. Carapace and the piastrone, much sturdy, they are joined along the margins and they do not introduce hinges. Carapace smooth and a po' convex, while the piastrone, smooth (he is in the females that in the males). From small the carapace green clearly and, as they become adult, stretches scurir until becoming in some cases also dark brown. Piastrone yellow with one the every black spot scuto. The cute for devout the green, with strisce yellow and, to sides of the head, the two characteristics strisce of yellow color are present orange, but to times also. The Trachemys scripta troostii much similar one to the Trachemys Scripta elegans and for which easy to confuse it, the differences they are devout that other limiting to the color of the strip to sides of the head that in the red Elegans while in the yellow Troostii devout orange or, and the strisce yellow on the front limbs they are devout wide.
Behavior in the natural atmosphere
Trachemys scripta troostii one original sweet water turtle of the south of the United States. Adapted to multiple variet of habitat, but prefers rich atmospheres of vegetation with a muddy bottom and waters tinning calm and. Great part of the time passes on "the crogiolandosi" rivers or supported to log semisubmergeeed to the sun. This type of behavior, typical of the rectums them, which had to the fact that not having a system of regulations of the corporea temperature, has need of the heat in order to activate their metabolism and of the solar beams in order to synthetize the D3 vitamin, indispensable for the bony increase. Very rarely adventure on the firm earth if in order not to place eggs. Being an animal much timid, lessened noise is thrown in the water where, from skillful nuotatrice, dilegua fastly. To a smaller temperature of 10 C stops to feed itself and passes letargo sott' the water, hidden between the mud and sediments. In the beautiful days, less rigid, not rare to see them to exit for esporsi to the weak people beams of the sun.
Feeding in nature
The Trachemys scripta troostii is onnivore and in nature amphibious small, died fish, crickets, snails, worms, animals, aquatic plants etc are fed of. From small they are mostly carnivorous, in fact they remain in the less deep waters where the bugs abound. From devout adults they preprefer a rich diet of vegetables and stretch to occupy deep devout waters. They are fed in deep waters until 3 meters and remain calmly in apnea also for 5minuti.
REPRODUCTION
Like for the greater part of the rectums them, for the attainment of the maturit sexual, the dimensions are devout important that the years. Indicatively for, the males become mature around to the 3-4 years, caught up i 15-19 cm, while the females towards the 5 years, caught up the 15-20cm of carapace. The riproduttiva season orientativamente, to second of the localit geographic, varies from March to July. The male corteggia the female putting themselves and making to vibrate the water ritmicamente. The copula true and own hard approximately 15 minuteren. After approximately 4-6 weeks the ready female in order to place eggs, cos he tries a soft and humid land in the pressed ones of the water in order to place. To the term the female covers the nest. The eggs are ovoidali and flexible. During the incubation they absorb water becoming devout large and devout rigid. The female, to second of the dimensions, in a year pu to place until three times from 5 to 20 eggs, that they will employ 2 or 3 months for schiudersi. The baby hardly been born they are many defenseless small and (2-3 cm) and often they end in order to become prede.
Sexual Dimorfismo and determination of the sex
The sex pu to settle down itself once that the turtles catch up 6-7cm of carapace. The females are of greater dimensions and have one small and stocky tail. The devout males instead have one long and wide tail the many and nails of long legs front until 3 cm. The piastrone it does not introduce concavit n in the males and n in the females. Like for many families of resisted them the determination of the sex tied to the temperature of incubation of eggs. If the eggs are incubated under 27C avr a prevalence of males and the times of incubation that vary from the 100 to the 120 days. While, to an incubation over the 30C, they will be born mostly females and the times will vary from the 60 to the 70 days. To intermediate temperatures variable proportions of births will be had, between males and females. In commerce devout easy to find exemplary females in how much the breeders accelerate the schiuse increasing the temperatures.
Breeding in cattivit
The "turtles from the red orecchie" have been imported from the United States to ten of migliaia every year, but the greater part still died before being sold, because of the inadatte conditions in which they were held and once sold very many they died before a ET year, for lack of cures adapted from part of the owners, often parents, that these animals to the own sons without an adapted information gave or unaware of of all of the complessit that represents the breeding of these rectums them. Very many, once grown, and become too much cumbersome they came freed in several smalls lake or Italian rivers damaging the ecosystem and the local fauna. Just for this from some time sale of the Trachemys scripta troostii be restricted from an appropriate law that of it prohibits the import in Italy (even if this prohibition be raggirato from the importers who hour import Trachemys scripta scripta, than to the end is adapted exactly to our climates like the Trachemys scripta troostii). They are turtles that, if attended to adequately, live calmly also 30anni. The ideal dwelling would be aghetto, deep at least a meter, encircled from a retrenchment in order not to make them to scappare, supplied of some log semisubmergeeed and one one dry zone for permettergli of crogiolarsi to the sun and placing. In alternative to the small lake, the represented better solution from a acquaterrario opportunely equipped. One brace on i 10 cm pu living calmly in an atmosphere of 80 x 30 x 30 cm. Devout obviously large they will be the turtles and devout large dovr to be the bathtub. The water must be of one profondit such to allow the turtles to swim. Pu easy to be based adding to us to the length of the carapace, 5 cm. We would have cos for one turtle of 10cm of carapace, one profondit of the water of 15cm. In the acquaterrario dovr to be present one dry zone easy raggiungibile from the turtles and heated from a faretto "spot" from 40 W or 60 W in such way to have the temperature of the air on the 30C. The temperature of the water must be of 24-26C. E' a lot important to use as furnishings "stable" woods or cliffs that do not risk to falling and catching the turtles sott' water drowning them. Like advisable bottom to not too much use some until in order not risking that it is swallowed, provoking to the turtles an internal block. Most important to equip the acquaterrario with one fluorescent lamp with emission of essential beams UVB-UVA for the synthesis of the D3 vitamin. This lamp does not have to be mail to a glass or to of the plastic in how much the beams they would be shielded and therefore its turns out useless uses. The lamp must remain second ignited for 12-14 hours to the day and replaced written how much regularly on the confection (in every kind 6-12 months). In the beautiful days always better to expose the turtles to the direct light of the sun, being well attention to avoid overheating problems, above all for the small devout exemplary, fornendogli the possibilit to repair itself to the shadow if the temperature increases too much. One of the main problems represented from the hygiene of the water, that it must be maintained devout cleaned up possible if health problems are wanted to be avoided, for this advisable one to install a filter from Aquarius (in order to agree), a filter are mechanic who biological; the better choice consists in a filter of external type, to whose inside we can then insert a first filtering to sponges according to wool stage many cannolicchi ceramic for last the biological filtering and in a sanitary napkin for ammoniacal substances). Also with the use of a good system of filtering, the water must in any case be periodically changed partially (a fifth of the water total to week). For the great slag production, the dimensioning of the filter must be 4-5 times greater of the volume total of the bathtub, as an example, with 50 l totals, would have to at least acquire a filter for Aquarius from 200 liters.
Feeding in cattivit
The small turtles must every day be fed; as they grow the frequency of the meal goes diminished, until arriving to 2-3 times to the week in the adult individuals. The ideal of feeding the turtles in a separate bathtub in order to maintain the main Aquarius clean, or to put the food in a dry zone, even if the Trachemys prefers to feed itself in water. The bathtub used for the feeding goes washed and disinfected after the use. If the possibilit is not had to feed them in a second bathtub not to insert much food to the time in order not to create remainders that decomposing itself would pollute the water. The feeding in cattivit must be devout varied possible and composed it is from alimony of animal origin that vegetable. Optimal they are sweet water fish, molluschi, lombrichi, snails, pellet integrated with vitamins, carrots, lattuga roman, string beans, tarassaco, spinaci, alfalfa etc. The magimi gi it manifactures you that they find in commerce must constitute to the maximum 25% of the diet while they are strongly advices against to you as food the simple ones gamberetti essicca you in how much is completely cants to you and lacking in indispensable vitamins. These must exclusively be somministrati irregularly being single and leccornia. Turtles fed for along single time with gamberetti, end unavoidablly in order to develop serious vitaminiche deficiencies that can carry also the dead women. Also the red meat not a balanced food in how much poor one of rich soccer but of fat people. E' good norm "to dust" once to the week of the bone of small cuttlefish over to foods and once every 2 weeks to integrate with a little vitamins, remembering itself that a soccer excess does not involve particular problems while an excess of vitamins pu to cause serious problems. Many turtles refuse to assume vegetables. A trick in order to accustom them that one to stir of the vegetables to a food to they a lot appreciate, like pu being of the milled meat. With passing of the time, the quantit is reduced of the food to devout they appreciate and the quantit is increased of the vegetables.
Letargo
For the health of the Trachemys scripta troostii the letargo not indispensable, even if strongly advised in order to respect their natural cycles, while a lot important if it is wanted to be made to reproduce. If they are found in a terrario to the inside, the temperature goes gradually lowered in the course of some weeks until catching up the 4C. During this period they do not have devout to be fed in order to premise to their intestine to empty itself completely. The letargo, to second of ET of the subjects, pu to vary from the 6 to the 12 weeks. Fundamental E' that the temperature during the letargo, is comprised between the 10 and the 4. A advanced temperature to i 10 C does not allow the metabolism to slow down in way consona, making to too much consume in a hurry corporee reservoirs that do not come newly stored in how much the turtles are not fed; while temperatures under the 4C could create damages from freezing. As far as the letargo to the open, it must follow little but fundamental rules. The small lake goes constructed of a profondit minimal of 1 meter, in as far as 4C (minimal temperature that concurs with the turtles to exceed the winter) the temperature of the water has its maximum specific weight and comes down consequently on the bottom. Here perch on the bottom there are 4 C, even if to the outside the temperature comes down a lot under - 0 C and the surface freeze. According to some experts the surface does not have to be left ghiacciata for devout of two weeks. Turtles many small, sick or however in not optimal physical conditions, do not have to be sent in letargo and must pass the winter in a terracquario heated to 24-26C, illuminated for 12-14 hours to the day with one lamp to solar phantom.
