Ziphephile kubantu, kodwa akukhuthazwa ukubazithinte, njengoba zizozivikela ngokuluma okubuhlungu. Izimbungulu zidla ezinambuzane ezincane, kanti abantu abaningi bakondla izinhlanzi, ezinye ze-subspecies zingahamba. Nokho, benza lokhu kuphela ngenxa yokushintsha indawo yabo.
Isigciwane samanzi
Umndeni wezinambuzane zamanzi uhlanganisa izinhlobo eziyisithupha, hhayi okufanayo. Unayo usayizi womzimba kusuka ku-2 mm kuya ku-12 cm. Zihamba ngokuphila kwamanzi kuphela, futhi zonke ziyizilwane. Amanzi amanambuzane adumile kunawo wonke angumqhubi wamanzi futhi ashelelekile.

Kukhona izinhlobo ezingaba ngu-700 zezimbangi zamanzi, okuyinto ehlukile komunye nomunye ngombala nangokwesayizi. Lesi sinambuzane sinomzimba omude, ohlangene, ongaba kusuka ku-1 mm kuya ku-3 cm. Izimbatho ezintathu zemilenze ziphuma kuwo. Ngaphambili - mfushane, kudingeka ukuthi ithathe ukukhiqizwa nokulawula ijubane lokunyakaza. Imilenze yangaphakathi neyindilinga isetshenziselwa ukunyakaza futhi ube nobude bama-1.5-2 izikhathi ezinkulukunomqhubi wamanzi omzimba.
Kungani abashayi bamanzi bengagcini izimbungulu, kodwa bagijima emanzini? Izinambuzane zigcinwa ebusweni bamanzi ngenxa yamandla okuphikisana kwawo. Ekhanda le-bug kunezintuthwane ezikhethekile ezikwazi ukubamba ngisho nokudumala okubuthakathaka kwamanzi. Izixhobo zomlomo zibhoboza-ziphuza, futhi zisetshenziselwa ukuncelisa okuqukethwe kwesisulu.
Amakhadi amanzi abeka amaqanda emaqabunga neziqu zezitshalo zamanzi. Ngezinye izikhathi abashadile, kodwa ngokuvamile amaqembu ezinhlamvu ezingu-40-50. Isibungu sibukeka njengomuntu omdala, kodwa sihlukile emzimbeni omncane owenziwe ngomgqomo kanye nosayizi omncane.
Umshayeli wamanzi uhlala emagodini ngamanzi aphansi noma imifula enemanto amancane kakhulu.
Ubani odla izimbungulu zomgogodla wamanzi nalokho okudlayo? Ungalimaza emaphethelweni emanzini. Idla ama-invertebrates, izinambuzane, i-fish fry. Ngenxa yamehlo amakhulu, umshayeli wamanzi uyakwazi ukubona inyamazane esivela kude futhi ayihlasele nge-proboscis yakhe. Bona ngokwabo baba ukudla kwezinhlanzi ezinkulu.
Umshayeli wamanzi wezithombe
Okulandelayo, uzobona izithombe zamagciwane okugeleza amanzi:
Ibhulogi yokulala
Isibungu sinomzimba omuhle kakhulu, ngenxa yokuthi le nambuzane ithole igama layo. Imilenze yangemuva ngezindlela eziningi idlula ubukhulu bezinye, futhi isetshenziselwa ngokuthi "i-paddles" lapho ihamba emanzini.
UGladysh uthanda amachibi amile, kodwa ngokuvamile uhlala kunoma iyiphi i-puddle noma ngisho nomgqomo ngamanzi. Angenza izindiza eside kuphela ebusuku ukuze athole indawo entsha ngokudla. Njengazo zonke ezinye izimbungulu, lobushelelezi unomshini wokubhoboza umlomo, owuhlaba umzimba wesisulu bese uphuza izakhi.
Iyiphi inkinga ye-sleek kanye nokuphefumula kwesitho sokuphefumula? Emanzini, lesi sinambuzane siguqulela isisu sayo phansi, siyihamba phezu kwegobolondo elibushelelezi. Kulesi sikhundla, isikhumba esibucayi siphefumula umoya olula womoya, othola ngokuvuleka okukhethekile ngemuva kwesisu. Ngesikhathi sokudonsa, inambuzane iqoqa umoya odingekayo, emva kwalokho ivalwe ngamacwecwe akhethekile.
Smooth inyamazane ngezinambuzane noma izinhlanzi ezincane. Ngesikhathi esifanayo, kungase kube yinto edla inyama yezinhlanzi noma izinyoni. Kodwa-ke, imvelo inikeze isivikelo kulezi zilwane - imhlane yakhe ilula futhi isisu sakhe simnyama.
Umbhede ubeka amaqanda phansi noma ngaphansi kwamanzi ingxenye yezitshalo. Ngemva kwamasonto amabili, izibungu zivela kubo, zifana nabantu abadala, kodwa zikhanya.
U-Gladysh akahlaseli muntu, futhi ngokuvamile emhlanganweni naye uzenza sengathi ufile noma uphonsa uketshezi oluvuthayo oluvikelayo. Kodwa-ke, uma uzama ukuthatha lokhu, ungathola ukulunywa okubuhlungu okuzolimaza isikhathi eside kakhulu, futhi ngezinye izikhathi kufinyelela.
Izimbungulu zamanzi ziwumndeni wonke ohlala kuphela emzimbeni wamanzi noma emifuleni enezintambo ezibuthakathaka. Ziyizilwane ezidliwayo, zinamadivaysi aphuza-okuncelisayo, ngosizo lwaluthola amajusi avela kumuntu ohlukumezekile. Ezinye izinhlobo zinamaphiko azokwazi ukuwahamba ukuze zithole indawo entsha yokuhlala. Izimbungulu zamanzi azihlaseli abantu kodwa angalwela ukuvikelwa ngokuletha ukukhala okubuhlungu. Okudumile kunayo yonke umqhubi futhi ubushelelezi.
