Uyini umehluko phakathi kukagundane nengwenya?
Izingwenya nezingwenya zinokufana okuningi, kuhlanganise nokuba nemilenze emifushane, imisila enamandla, nezimpondo ezinde, kodwa futhi kunezindlela eziningi zokuzihlukanisa. Okokuqala, ngokuvamile zitholakala ezindaweni ezihlukahlukene, njengoba izingwenya zithanda izindawo ezinamanzi amnandi kanti izingwenya zitholakala ezindaweni ezinamanzi anosawoti. Okwesibili, izindebe zazo zinemilo ehlukile, ngoba ama-alligator anemilomo ebanzi, emise okuka-U, kuyilapho imilomo yezingwenya imincane futhi imise okuka-V. Ngokuvamile ungakwazi ukubona amanye amazinyo aphansi engwenya, ngisho nalapho umlomo wayo uvaliwe, kodwa hhayi ku-alligator. Okokugcina, ama-alligator avame ukubonakala emnyama noma enombala ompunga omnyama, kanti izingwenya zibonakala zinombala onsundu noma omnqumo.
