Cordylus tropidosternum

Kruhochvosti byli jedním z prvních zvířat, které jsem si pořídil. Jedná se o krásný druh, který mě zaujal zejména svým vzhledem blízkým k vzhledu “draků”. Bohužel, jak už to tak v mém případě bývá, při svém výběru jsem nejprve narazil na druh Cordylus Giganteus a Cordylus Cataphractus, což jsou krásní, majestátní ještěři, kteří však patří mezi extrémně vzácné a extrémně drahé ještěry.

Abyste si udělali představu, o jaké zvíře se jedná, zde jsou nějaké fotky :-). Vlevo C. Giganteus, vpravo C. Cataphractus.

Bohužel, investovat 2-3 tis. € do takovéhoto zvířete, by při mých neprofesionálních znalostech znamenalo hazardovat jak s tímto krásným zvířetem, tak s investovanými penězi. Rozhodnul jsem se proto, že by bylo vhodnější začít s nějakým jedodušším chovem podobného druhu a volba padla právě na C. Tropidosternum.

Pro chov jsem po několika konzultacích pořídil trio, které se ihned po svém příjezdu chovalo velmi socializovaně, bez větších známek stresu. V teráriu se velmi rychle aklimatizovali a po pár týdnech se již takto bezstarostně slunili pod lampou.

C. Tropidosternum je oproti zmíněným “vzácnějším druhům” menší. Údaje o chovu zatím opětovně poskládané z různých zdrojů, časem upravím dle vlasních zkušeností.

Výskyt

Kruhochvost nížinný je pozemní ještěr, žijící zejména v kamených hromadách a křovinatých lokalitách v suchých lesích Jihovýchodní Afriky. Územně se K. nížinný vyskytuje od jižního pobřeží Keni až po výchovní Zimbabwe and centrální část Mozambiku.

Popis

Jedná se o denního ještěra. Zbarvení se pohybuje od hnědé, přes tmavě hnědou místy našedivělou barvu na zádech, břicho mají zbarvené světle hnědě až krémově. Ocas je velmi ostnatý. Dospělí jedinci dorůstají 160-190 mm na délku. Samci mají mírně širší hlavu, než samice (délka hlavy mužů, je asi 1,25 násobek šířky zatímco délka samice hlavy je asi 1,33 krát šířka). Samci bývají agresivní vůči ostatním samcům a je proto vhodné chovat ve skupince vždy jednoho samce.

 

Tropical Girdled Lizards are almost identical to the Limpopo Girdled Lizard (Cordylus jonesii) and the Ukinga Girdled Lizard (Cordylus ukingensis). Limpopo Girdled Lizards have smooth scales on the throat and belly (keeled scales in C. tropidosternum) and its nostril is in the center of the nasal scale (the nostril of C. tropidosternum is positioned in the lower posterior corner of the nasal scale). The Ukinga Girdled Lizard has distinctive white lips, a small ridge over each eye (supraocular ridge) and the loreal scale is fused with the preocular scale (separate in C. tropidosternum and C. jonesii).

The Tropical Girdled Lizard is exported from Tanzania and Mozambique for the pet trade where it is commonly referred to as the “Armadillo Lizard” or “Forest Armadillo Lizard or “Jone’s Armadillo Lizard.” Tropical Girdled Lizards are not flattened like the true Armadillo Lizard (Cordylus cataphractus) and do not grasp their tail and roll into a ball for defense. With gentle handling and plenty of hiding places, Tropical Girdled Lizards become excellent, long-lived pets and can be trained to accept food from their owner’s hand.

Habitat:

Ecologically, southern Africa is made of a complex of mosaic of different vegetation types. One of them is Mesic savannah, this covers the eastern regions of higher rainfall and warmer winters. As thee Indian Ocean belt, it extends as a narrow strip along the eaast coast as far south as Port Elizabeth. Here the warm Mozambique Current causes high moisture and warm weather; mean annual temperatures range from 26°C in the Zambezi Valley to 17°C at Port Elizabeth, and frost is absent. In the north, the belt, t extends 240 km inland across the sandy soil of the Mozambique Plain, and comprises rich Brachystegia woodland ( now replaced with secondary wooded grassland and cultivation ), with patches of mangrove and swamp forest along the coast. The vegetation is a mosaic of succulent and moist thicket, which may be dense and impenetrable. A secondary belt of more open Brachystegia woodland covers much of the Zimbabwe plateau.

Dry lowveld, particularly mopane savannah. The rain that falls in during the year, 90% is falling in october – march, and it falls more than 500mm pa.

Climate:

Southern Africa has a mainly temperate climate, with all season contrasts in rainfall and temperature. The rainfall is stronglly influenced by the cold Atlantic Ocean (Benguela) and warm Indian Ocean (Agulhas) current that sweep up and down the west and east coast respectively. The annual rainfall increases considerably in the north and east, whereas the west coast and adjacent regions are thr driest parts. Rainfall is largely dependent on the prevailing winds, which in summer sweep anticlockwise across the continent, carrying moist air in the form of thiúnderstorms from the Indian Ocean across the eastern regions. Because of the high altitude of the interior, little rain remains to fall in the west. In winter, the winds bring rain to the west coast, whereas the rest of the country is dry.

The temperature is affected by both the position (between 17° S and nearly 35°S) and the high altitude (1000 – 2000 m) of much of the interior. The cold Atlantic sea current sweeping up the west coast keeps the air temperatures cool, and causes local fogs that sweep across the Namib Desert, and on which many of the region’s reptiles depend for their water. Summer temperatures are highest in the Kalahari and surrounding regions, becoming less intense with altitude on the highveld of the Transvaal and Orange Free State and the Zimbabwean and Namibian plateaus. Coolest areas at this time are the high mountains of the eastern escarpment and the south-western Cape. Winters are mild along the east coast (the Mozambique Plain and adjacent lowveld of the eastern transvaal, and the Limpopo and Zambezi river valleys). The coldest winter regions are the highvelt and the mountains of the Great Escarpment, which regularly have night frosts and where (with the exception of the Namibian escarpment) heavy snowfalls are frequent. The rest of the region has warm, sometimes pleasantly sunny, winter days with cool, occasionally cold, nights.

Terrarium:

These lizard will climb if they can i wouldn’t say they were arboreal more semi however still give them space to climb i would say a 50x50x60 Exo terra would hold two however more space is always better only one male should be held per enclosure one male with multiple females can work however this is not guaranteed so be prepared to separate if you are going to add a new lizard to the cage it should be quarantined for at least 3 months so u can monitor it for any illness or parasites this is very important to do as illness may not show up straight away and may pass it on to other animals the animal should be held in a different cage/viv and preferably different room

In my terrarium I have fine sand and mopane roots to hide under, the temp is about 25 degrees Celsius in the tank and under the lamp it is 35 degrees Celsius, I have two 100 w halogen lamps. These lizards live in forests and they like to hide under wood and loose bark, in nature the live around treelogs and in arboreal areas.

Add damp vermiculite or other damp substrate to facilitate shedding.

Note:  If you provide too many hiding places, you may never see them again.  We made a clay warren of tunnels which delighted them, but also enabled them to disappear from view 99% of the time.  Face their hide boxes toward the front of their cage just in case.

Diet:

In the nature these lizards most of all love winged termites, but it is little bit difficult to get termites in captivity. They also feed on moths and spiders. Instead we can feed them with live crickets, grasshoppers and other insects that we find. In the summer we can caught insect from our own nature and feed them with, as long as we know that they are not toxic. Before feeding the lizards with the insects we have to powder them with some vita-mineralpowder, this you can buy in a petshop. They will also have UV-b light or D3 drops together with Ca in the drinking water. You will need to have a little waterbowl in their terrarium so they can drink and take a bath when they are changnin their skin.

It is not so much to say about their food, it is a little bit up to your self to see that they get the food they eat. I feed my with mainly waxmotts and crickets, but they eat all you give them, zoophobas, mealworms, spiders, catepillars beetles…….as long as it moves.

Supplements.

One weekly powdering of your crickets with a calcium/vitamin supplement usually suffices.  Don’t go overboard on this stuff.  The adults don’t need much.extra calcium because their bones are mostly alreasy grown.

Water.

Provide a water bowl that’s easy for your Armadillo Jines to get in and out of.  Put a rock in the middle for your crickets.  Change their water if your lizards use it for a latrine.

Sexing

Sexing is difficult with this species in particular most people sex by the shape of the body females are slim an have sweeping curves whereas males are more broad.

Do you know how to sex these lizards? You look at the shape of the body, the female have nice kurves and not as thick before the tail as the male…..the male look more robust in the body and is more broad between the rear legs.

Breeding

Breeding requires brumation/hibernation for 6-8weeks at 10-15c, ideály in March and April.

Before brumation is initiated food should be slowly cut down until you do no feed and lighting should be slowly shortened this will give them time to digest the food and then slow down their metabolism if they are feed while they are about to brumate or while they are brumating food will rot inside them.

Když se zvířata proberou, je potřeba je hodně krmit, zejména samice, aby nabraly hodně síly. They give birth to two to four live babies in the fall.  Remove the little guys.  Big lizards usually eat little lizards.

 

A year in my lizards life:

January and February: , We get much food, crickets, mealworms,zoophobas, we have to eat much to get ready for hibernate, in the middle of february we do not get any more food and we get a little bit less light and heat, only water, this last until the beginning of march.

March: We are put away into a dark cold place ( temp :10 – 15 degrees Celsius) and only a little light every day, we need a water bowl or something so we can drink, now we are staying here for about 6 – 8 weeks…..we have to be looked at some days a week so that we are ok, if we not you have to take us out from the cold place and let us wake up, but not to fast, take us out and let us be in the tank for two days, in the inhibitate tank I have sand and some stone to hide under.

April: Middle of april we come out again, little light and heat for some weeks, we usually mate now and the babies do not come until the autumm, I get mine around week 44. You see if the female get thicker and thicker and the time will never come until the birth….they are livebearer so the small ones will show up from nothing…

May-Sept: Full light and heat from now,If it is possible we want to be outside in the sun…….do not forget to give us a water bowl…we have a lot of crickets together with us in our outdoor tank…sĺ if we are hungry we just eat one.

Okt – Dec: We stay inside, this is our normally spring/summer and we just enjoy the “sun” and eat as much we want.
