Nomnikelo Fish okanye akunjalo? Yintoni yenzululwazi ithi?

Emva kokuhlolisisa bonke imiba ingxaki, abaphengululi baye bafumanisa ukuba isiselo intlanzi akufani. Ngakumbi ukuba uthi - musa ukusela, kwaye bafumane amanzi emzimbeni wakho. Ngapha koko, ulwelo ngenela kuzo zonke iinkqubo metabolic. Ngaphandle kwalo, umsebenzi ubomi bekuya kuba nzima. Nantso into abayenza.

abahlali amanzi

Ezi ubuhle emzimbeni yabo ityuwa kakhulu bawazondayo amanzi ukutya oko ingafuneki. Kubonakala ukuba intlanzi asele umzimba, kungekhona emlonyeni. Ngokwalo, inkqubo angamelwa ngolu hlobo. Ukuba ufake ulwelo ezimbini ezilandelayo ezahlukeneyo lamanani neetyuwa ichithwe kuzo, vula vana, apho kumda wesangqa ye kwe- ziya kuthunyelwa? Injalo loo nto, kwicala kolwelo ifumile. Uphakamile xi ityuwa, kokukhona 'unxano "kubuhlungu. Amanzi iqala ukuba aye ifumile amanzi acocekileyo iqulethe imali encinci kwezithako, zaphembelela osmotic phantse zero. Intlanzi - phezu koko. neetyuwa zomzimba kakhulu. Kubonakala ukuba kusoloko kwanya bume. Kwaye main umsebenzi wabo Asinto le ukufunxeka kunye zinomgutyulo. Le nkqubo ayilungiswanga, kungenjalo abemi amatsha ukuze kudumba uqhume, umpompozo kangaka ngaphakathi emzimbeni. Kubonakala ukuba le ntlanzi abasela ngendlela original kakhulu. Anciphisa ulwelo iimfuno zakhe, kwaye ulungise uxinzelelo yawo ngaphakathi.

abemi marine

Ezi abemi amanzi amtyuba nkqubo zitshintshile. Elwandle, xi ityuwa iphezulu. Isalathisi xi osmotic ilingana ezingamashumi amabini umoya. fish Marine amanzi ngamaxesha onke. Bathi nje ukuba azondle rhoqo koovimba ayo, ngokuba kokusingqongileyo usoloko 'owomileyo "zabo, amanzi Amagqabi iphumela emzimbeni wonke. Inyaniso kakhulu ohlekisayo. Xa zeentlanzi zaselwandle othululwayo amanzi - basahleli kakuhle. Misa - ungakwazi "koma 'kufa ngenxa yokulahlekelwa kolwelo. Kwaye oku, ukuba rhoqo emanzini! Kodwa ke imithetho kwe-. Uxinzelelo osmotic ngaphakathi imizimba iintlanzi ezilishumi kuphela umoya elinesihlanu. Ngaphandle - ngaphezu kabini nje phezulu. Oluya kubalelwa ama neentlanzi amahlwempu asele ngokuqhubekekayo ukuze sisinde kwaye hayi ukuba "koma". Okubangel 'umdla kukuba bafuna amanzi amatsha ngenxa yobomi. Bona yayo "ecociweyo 'ngokususa iityuwa yi iintsalela dj. Kunjalo kunokwenziwa, ezifana iingwenya. Ezi iityuwa zisuswa nge namadlala lacrimal. Xa ingwenya imnandi ukuba adle, ekhala. Le ityuwa engaphezulu ephuma emzimbeni.

Sharks ray

Ezi abahlala hlabathi-ulwandle ezichongiweyo kwiklasi ekhethekileyo. Izizathu zoku sengqondo "nomkhethe 'ukuba iindlela ulwalamano lwabo bume eyahlukileyo kakhulu kwabanye abemi yolwandle. intlanzi ekuthiwa musa ukusela njengokuba abanye. Bona "safunda" ukujongana ngenye kwizisombululo umahluko xi osmotic. Baya kuhlala urea zabo egazini, nangona luyingozi kakhulu. Ezi zidalwa nayo imvulophu okhethekileyo iigilizi - ukukhuselwa iityuwa kwemfuneko. Ngaloo ndlela, imitha nookrebe okuzixhasa kwiinzame xi ityuwa ngaphezulu kwisithuba ezingqongileyo. Izazinzulu zikholelwa ukuba oku sisalathisi abemi bamandulo kweelwandle. Bona, ezifana amatsha, wanye ulwelo kulo lonke.

Kutheni iintlanzi abakwazi ukuhlala kuyo nayiphi na indawo

Umahluko phakathi indlela yentsebenziswano neencindi ayikuvumeli ukuba bagqwese zonke isithuba Ocean jikelele. Abo benza kakuhle emanzini aphilileyo, uya kufa elwandle. Vice versa. Lo mgaqo kukho ukuxolelwa. Ngokomzekelo, wonke umntu uyazi ukuba ezinye intlanzi ubomi ngokugqibeleleyo ngamanzi netyuwa, Awandise emilanjeni. Oko kukuthi, ukuba diadromous - aphile ngayo nayiphi na bume. nokuba okusela intlanzi amanzi kule meko ixhomekeke kwi imeko ulwelo ezingqongileyo. Bavakalelwa umzimba, yintoni ulwalathiso wafudukela inkqubo, yaye kwimeko abasweleyo, baqale asele amanzi. zangaphakathi ngokukhawuleza wakhiwe yi ngoLwesithathu.

Le nkqubo reverse na emzimbeni Qhotsa xa zehlela endaweni yawo yemvelo - ulwandle.

ukuba umdla

Izazinzulu ziye zafumanisa omnye mmi, nako ukulawula imali kwamanzi ngendlela original. Frog cynomolgus - lwafunyanwa kutshanje zamasele - yindlela engaqhelekanga yobomi. Uhlala elwandle, kodwa zizala kwiindawo amanzi. Njani kunokwenzeka oku? Ukuze benze oku, indalo wasungula indlela ekhethekileyo. Ukuze kufa, oko uyakwazi ukunyenyisa inqanaba urea egazini. Xa diving elwandle - it oluhlala. Buthani ukuba ujungujungu - inqamla balahle urea. A amasele ezincinane, xa bekhula, kakhulu, ufunde ukusebenzisa le ndlela ukuhamba phakathi amachibi.
