Izimangaliso zomhlaba wesilwane azipheli. Lapho le ndawo ifinyeleleka kalula, abahlali abahlala kuyo baqabuka ngokwengeziwe. Ngaphezulu, okujwayelekile, nangaphansi okusobala, okufana nengilazi, i-amphibian engenamsila, ihlala ezindaweni ezishisayo zaseNingizimu Melika.
Izici nendawo okuhlala kuyo ixoxo lengilazi
Ezixhaphozini ezingangeneki eningizimu yeMexico, enyakatho yeParaguay, e-Argentina, lapho kungekho muntu ongafinyelela khona, ingajulile ingilazi yesele (Centrolenidae) uzizwa ekhululekile. Amabhange emifula nemifudlana egeleza phakathi kwamahlathi aswakeme kakhulu yindawo eyintandokazi ezindaweni zakhe zokuhlala. Isidalwa uqobo lwaso, sengathi senziwe ngengilazi, esikhumbeni singabonakala ngaphakathi, amaqanda.
Iningi lama-amphibians linesisu "sengilazi", kepha sitholakala sinesikhumba esibonakalayo emhlane noma emilenzeni eguquguqukayo ngokuphelele. Kwesinye isikhathi izitho zihlotshiswa ngohlobo lwomphetho. Incane, ingabi ngaphezu kwamasentimitha amathathu ubude, iluhlaza okotshani, umbala oluhlaza okwesibhakabhaka onamabala anemibala ehlukahlukene, ngamehlo angajwayelekile, anjalo incazelo kanye ingilazi yeselesele isithombe.
Esithombeni kuneselesele lengilazi
Ngokungafani nesihlahla sasemanzini, amehlo aso awabheki ezinhlangothini, kepha aya phambili, ngakho-ke ukubuka kubhekiswe engxenyeni engu-45 °, ekuvumela ukuthi ulandele ngokunembile inyamazane encane. Kukhona uqwanga oluthile esithendeni.
Ama-subspecies ase-Ecuadorian ama-amphibians (i-Centrolene) anemingcele emikhulu efinyelela ku-7 cm. Inepuleti lesisu esimhlophe namathambo aluhlaza. I-humerus iqukethe ukuphuma okuxhunyiwe. Inhloso ehlosiwe ye-spike injengethuluzi lapho kudonswa insimu noma abobulili obuhlukile.
Isimo nendlela yokuphila yexoxo lengilazi
Kwakuse-Ecuador ekupheleni kwekhulu le-19 lapho kutholakala khona izibonelo zokuqala, futhi kuze kube sekupheleni kwekhulu lama-20, labo bantu basemanzini bahlukaniswa baba yizizukulwane ezimbili. Uhlobo lokugcina olukhethiwe 3 i-mesh glass frog (I-Hyalinobatrachium) ibonakala ngokutholakala kwethambo elimhlophe, ukungabikho kwephedi elikhanyayo, okuthi kuzo zonke ezinye "izihlobo" kumboze umbono wenhliziyo, amathumbu, nesibindi.
Lezi zitho zangaphakathi zibonakala ngokusobala. Isikhathi esiningi sempilo yawo wonke amaxoxo senzeka emhlabeni. Abanye abantu bakhetha ukuhlala ezihlahleni, bakhethe indawo enezintaba. Kepha ukuqhubeka kohlobo kungenzeka kuphela eduze kwemifudlana.
Njengoba zihola impilo yasebusuku, ziphumula kumata omanzi emini. Ama-Amphibians Hyalinobatrachium akhetha ukuzingela emini. Amaqiniso athakazelisayo ngexoxo lengilazi yizici zokuziphatha phakathi kwabobulili obuhlukile, ukwabiwa kwezindima lapho kubekwa amaqanda.
Abesilisa bagada amahora abo okuqala okuphila, bese bevakasha ngezikhathi ezithile. "Obaba abakhulu" bavikela i-clutch ekungabikho kwamanzi noma izinambuzane isikhathi eside (usuku lonke). Kunombono wokuthi ngokuzayo banakekela nentsha ekhulayo. Ngemuva kokuzala, abesifazane bazo zonke izinhlobo bayanyamalala ngendlela engaziwa.
Ukudla kwexoxo lengilazi
Phakathi kwamagama eziphila ezweni nasemanzini Ixoxo lesingilazi laseVenezuela, anikezwe yena ngokwendawo. Njengawo wonke ama-amphibians "asobala", akaneliseki, uthanda ukuzitika ngama-arthropod amancane, izimpukane, omiyane.
Ngokubona kwesisulu esingahle sibe khona, uvula umlomo wakhe, amhlabe ibanga ngamasentimitha ambalwa. Isimo sezulu esinesiphepho sikuvumela ukuthi uthole ukudla hhayi kusihlwa kuphela, kodwa futhi nangesikhathi sasemini. Ngaphansi kwezimo zokuphila ezingezona ezemvelo, izimpukane zeDrosophila zikulungele ukondla.
Thenga ixoxo lengilazi Kunzima kakhulu, yize kunezikhungo zesayensi zokutadisha lezi zilwane ezingavamile, bambalwa abathandi bama-amphibian abazigcinayo. Izidingo zokuzalisa abathunjwa ziyinkimbinkimbi, zidinga ama-aquaterrarium akhethekile amade ane-ecosystem elinganiselayo.
Ukuzaliswa kanye nempilo yexoxo lengilazi
Isikhathi sokukhiqiza siqala kuphela ngenkathi yemvula. Eyesilisa, isusa izimbangi zayo ngokukhwishiza noma ngokuhlasela, iqala ukushela insikazi. Imiphi imithwalo ayikhiphi, bese ithi ngempempe, bese iba mfushane ngokungazelelwe.
Esithombeni kuneselesele lesilazi eline-caviar yalo
Kwesinye isikhathi hlangana isithombe sengxoxo yengilazi, lapho abantu babonakala begibela ngaphezulu. Ukukhwelana okunjalo kubizwa ngokuthi yi-amplexus, lapho umlingani ebamba khona owesifazane ngezidladla zakhe, engayikhiphi imizuzwana noma amahora.
Amaqanda abekwa ngokucabangisisa epuletini elingaphakathi leqabunga lezitshalo ezikhula ngaphezu kwamanzi. Izinyoni azikwazi ukuzibona, izakhamuzi zasemanzini azikwazi ukufinyelela kuzo. Ngemuva kokuvuthwa kwamaqanda, kuvela onoshobishobi, abawela masinyane entweni yamanzi, lapho kulindwe khona ingozi.
Isikhathi sokuphila nokufa kwama-amphibian akuqondakali ngokuphelele. Ayikho indlela eqondile yokunquma ubudala bezilwane ezihlala endaweni yazo yemvelo. Kepha ososayensi bathi ngokwemvelo, impilo yabo imfushane kakhulu. Imininingwane egciniwe yokuhlala lapho ubhukha khona:
- isigaxa esimpunga - sineminyaka engama-36;
- ixoxo lomuthi - uneminyaka engama-22;
- Ixoxo lotshani - 18.
Akunakwenzeka ukuthi noma ngubani ovela ezinhlotsheni zamaxoxo eCentrolenidae abe nesikhathi eside kangako. Ngaphezu kwezinkinga zemvelo kanye nezinsongo zokuqedwa kwamahlathi, kunamathuba amaningi okungena kwezibulala-zinambuzane endaweni yasemanzini lapho kuhlala khona amawundlu onoshobishobi. Ziyikudla kwezinhlanzi nabanye abameleli bezilwane, ngakho-ke izilwane zasolwandle "ezisobala" zinganyamalala emhlabeni wezilwane.
