Kodi kudziwa zaka kamba dziko? njira ziwiri zosavuta

eni akufunsa zaka zingati chiweto chawo, pa nthawi imene iwo ali m'manja a anthu mwachisawawa. Kudziwa mmene kudziwa zaka akamba za, m'pofunika kudziwa kapangidwe ka carapace awo.

Akamba mu chikhalidwe

Choyamba, tidziwe bwino za fulu, chifukwa pamaso panu zidzathera mu nyumba ndi chokwawa, muyenera osachepera amadziwa pang'ono za iye. Choncho, fulu, izo ndi za ku Central Asia, iye ali steppe. Ngakhale iye adayitana steppe, koma malo mbadwa ya mitundu ali m'chipululu cha Asia Central.

Kamba chakudya chomera chakudya. Zima zimabisala. pamsinkhu wobereka limapezeka pafupifupi zaka khumi. Akazi kutchera mazira angapo, koma osati zonse mwakamodzi, ndipo ndi imeneyi ya masiku awiri. nsikidzi akhanda ndi kutalika kwa 30 mm. N'zochititsa chidwi wangobadwa, nthawi yomweyo burrow mu nthaka, kumene iwo m'nyengo yozizira, ndi kuphuka pa chifuniro.

Kapangidwe ka kamba ndi

chokwawa uyu ali miyendo inayi, kutsogolo kwa iwo - tetradigitate. Carapace anamaliza ndi waufupi, mtundu angakhale osiyana mithunzi ya mawanga achikasu-bulauni kapena chikasu wobiriwira, wakuda kapena zofiirira pa chilichonse mbale. mtundu Zimenezi zimathandiza chigoba wangwiro mwa mchenga ndi udzu wouma.

Kodi kudziwa m'badwo wa dziko kamba? Njira imodzi - pa kutseka kuti uchiwo usatuluke wa chigoba chake. Amakhala wa carapace (dorsal) ndi plastron (ventral). Mu akhanda akamba chipolopolo ndi yofewa, pang'onopang'ono ikamauma. Plastron ogaŵikana kutseka kuti uchiwo usatuluke 16. Carapace ali 13 kutseka kuti uchiwo usatuluke chapakati, laterally oyenerera zina 25, ang'onoang'ono kukula.

Pa chishango carapace ali grooves tofanana mabwalo pa gawo la mtengo. Tsopano, kodi inu mumadziwa kudziwa zaka kamba dziko? Inde, chimodzimodzi monga m'badwo wa mtengo - mphete.

Kuona zaka kamba m'njira ziwiri

Choncho, njira yoyamba ya mmene kudziwa zaka kamba dziko - concentric mphete. Iwo anawonekera lakutsogolo la akamba kakang'ono mu chaka choyamba cha moyo. Ndipo mu zaka ziwiri zoyambirira za kukula ndi kwambiri, ndi poyambira pa chipolopolo pamaoneka pambuyo 3-6 miyezi, ndiyeno - 1 kapena 2 mphete pa chaka. Ali ndi zaka zingati wakale oimira mitundu zovuta kuphunzira, chifukwa carapace amakhala osalala, ndi grooves pafupifupi zosaoneka.

Yankho kukhala zolondola, inu mukhoza kuwerenga mphete pamatabwa 3-5, ndiyeno kuwerengetsa pafupifupi. Njira sapereka chifukwa wangwiro, chifukwa akamba zoweta si njira ya moyo, onse mu chilengedwe.

A zimakhudza kwambiri pa chitukuko ndi zinthu m'ndende ndipo ngati iwo kugona m'nyengo yozizira. Kusisita akamba yaitali asanafike msinkhu kuposa achibale awo okhala mu chilengedwe, ndipo amakhala moyo wautali (mpaka 20, ndi m'mikhalidwe yabwino, ndi zaka 30).

Pali njira ina mmene kudziwa zaka kamba dziko. Kuti tichite zimenezi, kuyeza mzere kutalika carapace lapansi. Amadziwika kuti mpaka zaka khumi, zokwawa amenewa akukula kudya mokwanira. Akafike kutalika za 18-20 masentimita kukula kubweza pansi ndi kukhala pafupifupi sichinasinthe. Ngakhale chikhalidwe pali toyesa kuyeza za 30 cm.

nsikidzi akhanda ndi kutalika 3 cm kwa chaka cha kukula ukuwonjezeka awo pafupifupi kawiri (5 cm) ndipo chaka wotsatira wa moyo akuwonjezera za 2 cm. Akazi kukula kwambiri lalikulu kuposa amuna. Tikuyandikira ena kuwerengetsera yosavuta kuphunzira mmene kudziwa zaka akamba dzikolo; ngati, mwachitsanzo, carapace kutalika kwa masentimita 14 chinyama, iye ali pafupi 6 zaka.

Kumene, njira izi kudziwa m'badwo wa pafupifupi kwambiri, koma ntchito onse, mukhoza osachepera ziri kudziwa yaitali bwanji ankakhala dziko Pet.
