Ngaba uyazi ukuba ulale njani kit? Phi kwaye njani belele unjengengwenya emanzini?

Mhlawumbi abantu abaninzi esazibuza ebuthongweni ngayo whales. Kubonakala ukuba le esinomdla isihloko kakhulu anakanyisisa. Ngapha koko, ukuba ubukhulu umzimba enkulu, inxalenye enkulu ubunzima oko izihlunu adipose, iminenga emikhulu kufuneka ukubagcina encinane. Oku kuthetha ukuba isilwanyana akukho intshukumo umsila wayo kancinci uza ajule.

ingafumaneka kweli nqaku, njengoko umnenga yokulala. kutshanje Izazinzulu ziye zafumanisa impendulo yalo mbuzo kakhulu umdla.

Olunye ulwazi ngokubanzi malunga iminenga

Iminenga - ezanyisayo apha naphaya ngokupheleleyo kubomi emanzini besive umyalelo Cetacea. Njengoko porpoises kunye dolphins, ezi ezincancisayo zasemanzini yenzekile, kukholelwa ukuba uvela izilwanyana ilizwe babuyileyo amanzi malunga nezigidi ezingama-50 kwiminyaka eyadlulayo, emva kokuphila emhlabeni kwizigidi zeminyaka eyadlulayo.

Nje bemiyo phezu komhlaba 2 suborder of iminenga: ikhamisile kunye sengathi. Kuba sengathi ziquka iminenga amadlozi, iminenga umbulali kunye ukutya. Uzingela emanzini olunzulu sentlanzi enkulu. Iminenga ikhamisile (zeBRT lokucoca): blue mnenga. Badla eziphilayo ezincinane, ezifana kwizidalwa, krill njalo njalo. Xa emlonyeni, banalo isixa esikhulu Amanzi olwandle ngokusebenzisa uhlobo esiqwini ikama-like ebizwa ikhamisile.

Phambi kokuba uyazi phi kwaye njani lo mnenga zokulala emanzini, chitha ukhenketho encinane ngemihla yamandulo.

Malunga iminyanya kweminenga

Ukuba elide ukuba zidade phezu kwamanzi, ukudinwa, nakweyiphi imeko uthathe indawo yawo, ngoko nayiphi na into ephilileyo ukuphumla kunye nokulala. Ngokupheleleyo zonke izilwanyana ezanyisayo kufuneka ubuthongo, kakhulu, kubandakanywa nabo bahlala emanzini: Iminenga kunye namahlengesi. Iintlanzi amaxesha zethu, oko kuvela ukuhlangabezana nale ngxaki "esithubeni." Kodwa ookhokho babo, njengokuba sisazi, izigidi ezininzi kwiminyaka eyadlulayo kwakukho izilwanyana ezisentlabathini.

kitokopytnye yaMandulo (pakicetus), eshiya umhlaba, baya kanye olwandle. Oku kungenxa phambi ezinzulwini ukutya kwayo ezahlukahlukeneyo, luninzi kwaye ifikeleleke ngakumbi.

Ixesha pakicetus yokuqala zandizingela ifu intlanzi, waza wabuyela koko ukuyekelela elunxwemeni. Ke akhoyo ngelo xesha olu khuphiswano iye kunyanzeleka ezi zilwanyana abalithimbayo ukukhukulisekela udeske ezinzulwini amandulo Tethys Ocean. Kwaye ngoko ke shwaka ngokupheleleyo ukuba babuyele kulo ilizwe, kwaye ngoko ke kukho imfuneko yokuba bafunde balala ngamanzi. Pakicetus bakwazi ukuziqhelanisa kule kwizigidi zeminyaka. Eli binzana ayimangalisi, kuba isilwanyana ofuna ukuba uma- ubusuku emanzini, kufuneka boyise imiqobo emininzi ebulalayo.

Ngokubanzi, iminenga badla ukulala, kodwa hayi ixesha elide. Xa ezi ngxilimbela antywiliselwa ngayo emanzini, balala nje imizuzu embalwa. Xa iyonke, iminenga kufuneka ixesha lokulala malunga imizuzu eli-15 ukuya kwiiyure ezimbalwa losuka.

Ubhaptizo esi sidalwa elikhulu ulwandle kuthatha indawo ubunzulu encinane, apho ikhithi reflex intshukumo komsila kwakhona liphuma ku wobuso esinye isithuba zezulu ukurhogele. Lo mjikelo kuphindwa kwakhona kwaye kwakhona. Oku kuyafana imeko ndoda yokozela "oludlekayo impumlo." Le indlela oominenga mikhulu, kwaye uyakwazi ukufumana emashumini embalwa imizuzu ukulala iiyure ezimbalwa.

Izazinzulu ngaphambili ayikwazanga ukuqonda indlela whale yokulala osoloko baqubha yaye sihamba rhoqo. ngoku Kuye kwacaca. Ngoko ke oosonzululwazi baye ngawo omane imfundiso yokuba kweminenga ukulala inkqubo efanayo kwinkqubo olukhoyo dolphins.

Yaye njani dolphins ukulala? A kancinane ngaphambili, oko kwazeka ukuba dolphins zinendlela olunzima kakhulu eziphilayo. Baye zifaka ezimbini ubuthongo ingqondo ngexesha, ngokunxulumene apho eku xhulumaneni, ngokungafaniyo China, uyakwazi rhoqo ukuhlala siphaphile.

ngeengozi

Kanye ulele unjengengwenya emanzini? Kunzima ukucinga, ekubeni umsebenzi wabo zintsonkothe kakhulu. Kutheni?

1) Ukuwa ubuthongo emanzini, ezanyisayo basengozini yokubulawa kukugodola, kuba ubushushu eyenziwe umzimba, ngokukhawuleza uyakhululeka kokusingqongileyo. Kwaye ngenxa yokuba amanzi a conductivity ephakamileyo oshushu komoya, oko lupholisiwe kwizilwanyana ngokukhawuleza.

2) Ngokungafaniyo iintlanzi, iminenga kufuneka popups periodic ukufumana inxalenye ethile zezulu. Ngoko ke, kufuneka athathe omninzi umgudu, ukuze umzimba abazange bavumele nzulu kakhulu. Kungenjalo, kukho amathuba ukumka namanzi.

3) eziphilayo ezincinane iintlanzi (dolphins kunye pinnipeds) ephupheni ingaba ixhoba ezidla, ngokuba kungekho manzi kwiindawo lukhuselwe ku yokuhlala ingowokulala, uze kumphezulu rhoqo ukuba ukuba umoya. Kwaye apho rhoqo kwaye ukuhlasela ezidla.

Kubonakala ukuba ukulala na ukuba iintlobo iintlanzi, ingakumbi ngenxa ookhokho babo - uvavanyo lokwenene.

A kancinci malunga neempawu

Into ephambili umdla - le yindlela umnenga yokulala. Kodwa kukho ezinye iingongoma ezinomdla kwezi ezanyisayo.

1. Ngokutsho etymologists ezininzi, igama elithi "mnenga 'sisuka hwal yaseJamani. Kodwa kukho uluvo lokuba isuka ilizwi IsiNgesi endala elithetha 'ivili', njengoko ngasemva sisilwanyana esincancisayo, esebenza phezu kwamanzi, ifuze ngohlangothi kwevili enkulu.

2. Iminenga Uphawu kunye nezinye iintlanzi ezinkulu kukuba ahamba emanzini ngenxa yezo intshukumo nkqo phezulu phantsi. Oku kwahlukile ukusuka intlanzi, imisila ogama xa kuntywilwa emke ngapha nangapha.

isiphelo

Kanye phezu ixesha umbuzo indlela umnenga ukulala, iingqikelelo kuphela impendulo. Phambi kokuba ukudalwa inkwili yokuqala kwakunzima ukwenza nayiphi na izifundo ubomi ezinzulwini zolwandle kunye neelwandle.

Kangangexesha elide iphupha, kunye neminenga kunye namahlengesi eenzululwazi bekusoloko mfihlakalo. Enyanisweni, yonke into kakhulu ezinomdla kakhulu kwaye umngeni.
