Isingeniso: I-Crocodile Monitors kanye ne-Dimorphism Yabo Yocansi

I-Crocodile Monitors (Varanus salvadorii) yizilwane ezihuquzelayo ezinkulu ezihlala emahlathini aseNew Guinea naseziqhingini ezizungezile. Lezi zidalwa ezihlaba umxhwele zaziwa ngobukhulu bazo obumangalisayo, zifinyelela ubude obufika kumamitha angu-10 futhi zinesisindo esingaphezu kwamakhilogremu angu-70. Isici esisodwa esithakazelisayo se-Crocodile Monitors i-dimorphism yabo yobulili, ebhekisela emehlukweni ongokwenyama phakathi kwabesilisa nabesifazane bohlobo olufanayo. Ukuqonda lo mehluko kubalulekile kubacwaningi, abalondolozi bemvelo, kanye nabathandi bezilwane ezihuquzelayo ngokufanayo.

Usayizi Nesakhiwo Somzimba: Umehluko Oyinhloko Phakathi Kweziqaphi Zengwenya Yeduna Neyesifazane

Uma kukhulunywa ngosayizi nesakhiwo somzimba, ama-Crocodile Monitor angamaduna anesandla esiphezulu. Ngokuvamile makhulu kunabesifazane, kokubili ngokobude nesisindo. Abesilisa bangakhula bafinyelele ku-10 ubude ubude, kanti abesifazane ngokuvamile bafinyelela kumamitha angu-8. Ngaphezu kwalokho, abesilisa banokwakheka okuqinile futhi okunemisipha uma kuqhathaniswa nozakwabo besifazane. Lo mehluko ongokomzimba kucatshangwa ukuthi uhlobene nezingcindezi zokukhetha zemvelo ezibekwa ukuncintisana kwabashadile.

Ukhakhayi Nohlaka Lomhlathi: Ukuhlonza Iziqaphi Zengwenya Yeduna Nensikazi

Esinye isici esihlukanisayo phakathi kwe-Crocodile Monitors yesilisa nensikazi ilele kugebhezi lwazo kanye nesakhiwo somhlathi. Abesilisa banogebhezi lwekhanda olukhudlwana noluqine ngokwengeziwe, olubasiza ukuba basebenzise amandla amakhulu okuluma. Lokhu kuzijwayeza kubalulekile kwabesilisa ngesikhathi sezingxabano zendawo kanye nokuvikela indawo yabo ngesikhathi sokuhlangana. Ngakolunye uhlangothi, ama-Crocodile Monitors wesifazane, anogebhezi lwekhanda kanye nomhlathi omncane uma kuqhathaniswa, okubonisa izindima nokuziphatha kwazo okuhlukene.

Ubude Nomumo Womsila: Umkhondo Wokuhlukanisa Iziqaphi Zengwenya Yeduna Nensikazi

Ubude bomsila kanye nokuma kwe-Crocodile Monitors nakho kunganikeza izinkomba zokuhlukanisa abesilisa kwabesifazane. Abesilisa bavame ukuba nemisila emide futhi eminyene, esetshenziselwa ukulinganisa ngesikhathi sempilo yabo ye-arboreal. Ngokuphambene, abesifazane ngokuvamile banemisila emifushane futhi emincane. Lo mehluko ngobude nokwakheka komsila kungenzeka ungenxa yezidingo ezihlukene ezibekwe kwabesilisa nabesifazane mayelana nokuhamba nokuziphatha kokuzala.

Umbala namaphethini: Izimpawu Ezibonakalayo Zokuhlukanisa Iziqaphi Zengwenya Yeduna Neyesifazane

Umbala namaphethini kungaba yizinkomba eziwusizo zokuhlukanisa phakathi kwama-Crocodile Monitors abesilisa nabesifazane. Abesilisa bavame ukubonisa amaphethini ombala agqamile futhi ahluke kakhulu, okuhlanganisa imigqa emnyama nephuzi ngokugqamile emizimbeni yawo. Abesifazane, ngakolunye uhlangothi, bavame ukuba nombala othobile, kanye nemithunzi ekhanyayo ensundu noma eluhlaza. Lo mehluko wemibala cishe usebenza njengezimpawu ezibonakalayo zokuqomisana nokukhetha komngane womshado.

I-Hemipenes: Isici Sowesilisa Esikhethekile Seziqaphi Zengwenya

Isici esisodwa esikhethekile sabesilisa se-Crocodile Monitors ubukhona be-hemipenes. I-Hemipenes izitho zokuzala ezibhanqiwe ezitholakala ngaphakathi kwe-cloaca, okuyindawo evamile yokuvula umchamo, ukuzala, nezinhlelo zokugaya ukudla. Lesi sici esiyingqayizivele sivumela abesilisa ukuthi badlulise isidoda ngesikhathi sokukhwelana. Ngokuphambene, abesifazane abanalo ngokuphelele lesi sitho, okuqhubeka nokugqamisa i-dimorphism yobulili phakathi kwabesilisa nabesifazane.

Izimbotshana Zezinsikazi: Inkomba Ethembekile Yeziqaphi Zengwenya Yendoda

Izimbotshana zesifazane zingenye inkomba ethembekile yokuhlukanisa ama-Crocodile Monitors abesilisa nabesifazane. Lezi zimbotshana ziyizakhiwo eziyizindlala ezitholakala ngaphansi kwezitho zangemuva. Abesilisa banezimbotshana zesifazane ezinkulu neziningi uma kuqhathaniswa nabesifazane. Lezi zindlala zikhiqiza into enengcina okukholakala ukuthi idlala indima ekuphawuleni indawo kanye nokuxhumana phakathi kwabantu. Ukuba khona kwezimbotshana zesifazane kuyinkomba enokwethenjelwa yobulili besilisa kuma-Crocodile Monitors.

Ukuziphatha Okumaka Iphunga: Indlela Eyingqayizivele Yabesilisa Yokuxhumana

Ukuziphatha kokumaka iphunga kuyisici esiyingqayizivele esivezwa ama-Crocodile Monitors wesilisa. Abesilisa banezindlala ezikhethekile ezitholakala eduze kwe-cloaca yazo ezikhiqiza iphunga elimnandi. Asebenzisa leli phunga ukumaka indawo yawo futhi axhumane nokuba khona kwawo kwabanye abesilisa nabesifazane abamukelayo. Lokhu kuziphatha kuyisici esibalulekile samasu okuzala abesilisa futhi kudlala indima ebalulekile ekusebenzelaneni komphakathi phakathi kwezinhlobo zezilwane.

Ukuziphatha Nolaka: Izimpawu Ezihlobene Nobulili kuma-Crocodile Monitors

Mayelana nokuziphatha nobudlova, ama-Crocodile Monitors abesilisa nabesifazane abonisa izici ezihlukile. Abesilisa bavamise ukuba nezindawo futhi banolaka, balwa nabesilisa abayizimbangi ukuze bathole ukubusa kanye namathuba avikelekile okukhwelana. Abesifazane, ngakolunye uhlangothi, babonisa ukuziphatha okuthambile nokungenzi lutho, okugxile ekuzaleni nasekukhuliseni inzalo yabo. Lokhu kwehluka kokuziphatha okuhlobene nobulili kuqhutshwa yizingcindezi ezikhethiwe zokuphumelela kokuzala.

Izitho Zokuzala: Izimpawu Zangaphakathi Nezangaphandle Kwabesilisa Nabesifazane

Izitho zokuzala ze-Crocodile Monitors zesilisa nezesifazane nazo zihluke kakhulu. Abesilisa banamasende angaphakathi, akhiqiza isidoda, nezitho zangaphandle zokuhlanganisa (ama-hemipenes) zokukhwelana. Ezinsikazi zinezindlala ezikhiqiza amaqanda zangaphakathi, ezikhiqiza amaqanda, kanye ne-cloaca yokubeka amaqanda. Lo mehluko ezithweni zokuzala ukhombisa izindima ezihlukene zabesilisa nabesifazane enqubweni yokuzala.

Ukuvuthwa Kwezocansi: Iminyaka Efika Ngayo Iziqaphi Zengwenya Owesilisa Nowesifazane

Iminyaka yobudala lapho i-Crocodile Monitors yesilisa nensikazi ifinyelela ukuvuthwa ngokocansi ingahluka. Ngokuvamile, abesifazane bafinyelela ekuvuthweni ngokobulili cishe eminyakeni emine kuya kwemihlanu ubudala, kanti abesilisa bangathatha isikhathi eside, ngokuvamile bafinyelele ukuvuthwa phakathi kweminyaka emihlanu neyisithupha ubudala. Lokhu kwehluka ekukhuleni kocansi kubonisa amasu ahlukene okuzala kanye nomlando wempilo yama-Crocodile Monitors abesilisa nabesifazane.

Isiphetho: Ukuqonda i-Sexual Dimorphism ye-Crocodile Monitors

Kafushane, i-dimorphism yezocansi ekhonjiswa yi-Crocodile Monitors inikeza imininingwane ebalulekile kubhayoloji nokuziphatha kwabo. Ngokukhomba umehluko oyinhloko phakathi kwabesilisa nabesifazane ngokosayizi, ukwakheka komzimba, ugebhezi nokwakheka komhlathi, ubude nokwakheka komsila, imibala namaphethini, izitho zokuzala, ukuziphatha kokumaka iphunga, kanye nolaka, singathola ukuqonda okujulile kwemvelo yazo. umlando. Lolu lwazi lubalulekile emizamweni yokongiwa kwemvelo kanye nokwazisa ukwehluka okumangalisayo okukhona endalweni.
