Zinhlobo Umkhomo: uhlu izithombe. imikhomo Toothed: Izinhlobo

Imikhomo - esincelisayo amazing kakhulu abahlala expanses amanzi kule planethi yethu. Lezi zilwane m esikhulu ukuzedlula zoke abawaziyo namuhla. Ngaphezu kwalokho, ulwandle ingakamiswa kwehlwaywe, yingakho ososayensi ngezikhathi ukunikela izinhlobo ezintsha imikhomo toothed ngokuvamile ezincane, kodwa namanje. Whaling namuhla uye waholela yokuthi zinhlobo whale ngokuqhubekayo kokuba encishisiwe, kanye labantu babo, okuyinto udabuka kakhulu.

ngezigaba

Zonke imikhomo zihlukaniswe amaqembu amabili, lo okuthiwa suborders. Nakuba-ke Kuyaphawuleka ukuthi izazi ziye zakhomba ezintathu we suborder. Omunye wabo - the imikhomo lasendulo. Zonke amalungu aleli qembu sezishabalele, futhi uchaze kubo ayikho injongo ekhethekile. Sizokhuluma ngezilwane ukuthi basaqhubeka sintanta izilwandle nezilwandle, ngisho noma kukhona usongo zinyamalala.

Enye yalezi suborders - baleen imikhomo. Ngaphezu kwalokho, ngokuvamile abizwa ngokuthi "imikhomo zingokoqobo." Eyesibili suborder - imikhomo toothed. abameleli ezincane, ezihlanganisa amahlengethwa futhi porpoises, kodwa kamuva kule. Kufanele kuqashelwe ukuthi izinhlobo ezahlukene imikhomo angaphansi ekubhujisweni. Kahle kahle, lokhu kusebenza futhi nakulabo babe obuyigugu kakhulu kule mboni. Lokhu Umkhomo oluhlaza, umkhomo fin, Gorbach mina T. P.

zinhlobo Umkhomo: ohlwini, incazelo emfushane

Siqala ne imikhomo baleen nge kokubili kunawo futhi iningi lasendulo. Lokhu kuhlanganisa ezihlukahlukene zezinhlanzi whale ezikufanelekelayo ukunakwa kwakho. Akunzima ukuqagela ukuthi leso silwane ingatholakala kwi amadevu emlonyeni. By the way, whalebone futhi wayezazisa, ngakho lezi zilwane zivame yizisulu abazingela ngokungemthetho. Omele elikhulu le suborder - blue whale. ngabanye bhalisiwe Iningi ifinyelela ubude ngamamitha angaba ngu-30 futhi isisindo amathani 150. Futhi izilwane ngempela obunokuthula, elidla ukudla ugxile plankton futhi mollusk.

Umkhomo Bowhead kuyinto omele abavelele babengasiqondi baleen imikhomo. ngezinye izikhathi Ubude lokhu giant ifinyelela 20 metres, isiqu isilwane abamnyama, streak-DRM. Kuyaphawuleka ukuthi inhloko u-30% we Ubude imikhomo. Uhlala kuphela ezilwandle Arctic. Namuhla-ke cishe izinto eziphilayo, okuyinto evamile. Isizathu salokhu kwaba Whaling.

imikhomo yemifino kanye kwesokudla

Umkhomo Wik ilungelo kuthi akufane nokwenzeka ihabhu efana ababukeka ngosayizi. Ngakho-ke, ngomuntu ongenakho okuhlangenwe nakho kungaba ukudida kubo. Nakuba kulula ukuqagela ukuthi indawo yemvelo izilwane ihlukile kakhulu. imikhomo Wik kwesokudla engatholakali kwezilwandle Arctic, kanye Greenland wangabona ezonini esipholile zasePacific izilwandle Atlantic. Kusukela mayelana 10 leminyaka BC Whaling ku imikhomo kuphela wandisa. Namuhla lezi zilwane wokuvikela ngokugcwele, ngokuvumelana yakamuva idatha ukukhiqizwa kabusha Amathrendi kukhona uhlobo omuhle.

Zonke izinhlobo imikhomo, uhlu ongawabona kulesi sihloko kungabesifazane amangalisayo futhi eyingqayizivele. Ngokwesibonelo, cabangela izinkondlo, umkhoma yemifino. Lakhe okuthiwa ngenxa yobukhulu bawo amancane. abantu ngokuvamile ayibi ubude ezingaphezu kuka-6 wamamitha ubude. Kodwa uma singadli lokhu ipharamitha ku-akhawunti, bese Okusele akuhlukile izihlobo zabo.

imikhomo ezisengcupheni

Umndeni imikhomo grey ingenye kakhulu ngizoqothulwa ngesikhathi samanje. Kuyinto enkulu ngokwanele ngabameli 15 metres ubude, kungekho fin amaphiko. Ngekhulu le-18 sabantu olunezinombolo abantu kungathi izinkulungwane 30. Ngenxa yalokho, inani imikhomo asebenzayo grey Whaling kuya ku-1947 lasha abantu 250. Ngemva kwalokho, umkhaya wakubo imikhomo grey bekulokhu wokuvikela unomphela, namuhla lezi zilwane, kunezinguqulo ezingaba ngu-6000.

Ingasaphathwa umndeni rorqual. Lezi zinto zihlanganisa imikhomo yohlobo lwe-humpback futhi minke imikhomo samanje. Njengoba labo nezinye - whale izilwane ezisengozini yokuqothulwa. Uma ku 30s Ngasekuqaleni kwaleli khulu leminyaka, iya e-Antarctic, kwakukhona cishe 250,000 imikhomo fin, namuhla leli nani lingaphansi izikhathi eziyisihlanu. 100 000 imikhomo blue oke wahlala e-Antarctica, esikhathini esiyiminyaka engu-30 kuya ku-1962-i-mu kwasala abantu 1 000-3 000 kuphela. Cishe isimo okufanayo sei imikhomo humpbacks, okuyizinto eqashelwe njalo. Umhlangano omkhulu kunayo yonke imikhomo ezimthende omele - blue. Yena - kuphela zama-whale eholela yokuphila ayimizulane.

imikhomo Toothed: izinhlobo nezincazelo

Suborder kwemikhomo toothed has inqwaba imikhaya. Ayavumelana khona amazinyo, nakuba ubukhulu kanye nenani kungahluka ezibonakalayo. Cishe wonke amalungu kufanele usayizi umzimba ezincane. Okuwukuphela-sperm whale. Yiqiniso, amahlengethwa wasolwandle kanye porpoises kukhona edume kunayo suborder kwemikhomo toothed. Lezi yizilwane ikakhulukazi ezincane.

Indlela elula ukunquma ukubukeka whale white. Lokhu kungenziwa ngokukhumula ibala lesikhumba sakhe. Osayizi imikhoma ezincane ezimhlophe, ngokuvamile kuze 5 amamitha. Bathola cishe kuyo yonke indawo. Ngezinye izikhathi idatha imikhomo ukubhukuda lapho, lapho abakwazi ukuphila. Kuyinto engenakwenzeka hhayi ukwaba omele yedwa Narwhal uhlobo lwe - Narwhal. Ziyakwazi kuthi akufane nokwenzeka umkhomo emhlophe. Nokho, narwhals abe inzavula imitha-2-2.5 ekhanda lakhe, okungokukaNkulunkulu kuphela abesilisa. Ngakho ubude isilwane imayelana 5 amamitha.

Porpoises namahlengethwa

Lapha-ke sifika amahlengethwa subfamily. Kufanele kuqashelwe ukuthi sifaka inqwaba zinhlobo futhi zenyathi nakakhulu. Kuphela cishe isigamu sabantu namuhla eyaziwa imikhomo. Ngokwesibonelo, i-abavamile brown ihlengethwa vaquita noma umane ubude ngokuvamile bengekho ngaphezu kwama-2 amamitha. Ngemuva isilwane omnyama, futhi sesisu awube mhlophe. Amahlengethwa awazona esikhathini esiningi uthanda amanzi ukufudumala futhi ezindaweni ezinezinga lokushisa elithokomele. Ngokuvamile ukubhukuda kude futhi ngenyusa nemifula. Kazi ekhethekile uhlanga porpoises abahlala oLwandle Olumnyama.

Lezi zinhlobo ezilandelayo porpoises bahlala ezingxenyeni ezihlukahlukene ezilwandle nakuzo izilwandle:

• California;

• izibuko;

• omnyama;

• bespernaya Black et al.

Ukubukeka of zonke izinhlobo ezahlukene ebalulekile, kanye nosayizi. Nokho, Ngokuvamile, izilwane ezizingelayo, kodwa esinokuthula kakhulu. Ucwaningo luye lwabonisa ukuthi izinhlobo ezithile imikhomo namahlengethwa ubuchopho athuthukile kakhulu. Yini eyenza amahlengethwa eyisimanga kuyinto ikhono layo lokukhulumisana - amaza omsindo. Lolu hlobo ulimi, iningi nemisindo engaqondakali abantu namuhla.

Rod isidoda

Njengoba kuphawuliwe lisetudlwana imikhomo isidoda - kukhona imidondoshiya wangempela wawo wonke imikhomo toothed. Izilwane singafinyelela ubude cishe 20 amamitha. Lokhu whale abathanda abantu, okuyinto ingatholakala zonke izilwandle Zomhlaba. Okukhishiwe nabesifazane nemikhomo abasha ukuthi uthanda ukuba amanzi afudumele. Namuhla, it is hhayi wafunda ngokugcwele zilwane. Ikakhulu, akwaziwa ukuthi abesilisa ayobuya elide Ukuthuthwa yabo. Ososayensi namanje abazange esiphethweni kungani bebhukuda kuze kube manje, nakuba imfundiso yokuziphendukela kungenzeka kakhulu yangempela yokuthi bafuna ukudla. Ngokuya ukudoba isidoda whale ibaluleke kakhulu. Lokhu kwaba kwaphawuleka ngokukhethekile ngemva kwempi yezwe yesibili eminyakeni. Ngasogwini Chile nasePeru, lezi zilwane, ikakhulukazi abesifazane, abangu cishe yesulwe, okuyinto sina eyasongela labantu. Ngisho nanamuhla, kuzo zonke izilwandle zomhlaba ezingelwa futhi aqothulwe imikhomo toothed. Lesitshalo nge ukubaluleka ngokukhethekile muntu akanayo.

isiphetho

Lapha, siye sahlola izinhlobo ezinkulu imikhomo. Amagama la izilwane babelwa ukuba isizwe esisodwa emhlabeni hhayi kuphela ekhulwini lama-21. Ngeshwa, yokudoba esebenzayo ngisho nanamuhla. Bangaki zama-imikhomo ahlale namuhla? Mayelana 40, naphezu kweqiniso lokuthi kukhona esetshenziswa ukuba abangaphezu kwekhulu. Kungenye into lapho le nqubo ilawulwa, kuhlukile uma kukhona ukudoba engalawuliwe nasekubhujisweni.

Yiqiniso, ungakwazi bangaphezi ukhuluma ngalokho ikhiqizwa insulini kanye nezinye amahomoni, kwesibindi umkhomo ubuchopho ubuchopho - uvithamini A. Ngaphezu kwalokho, inyama isetshenziswa ukwenza ayi ezibizayo. Kodwa konke lokhu kungatholakala imvelo, ngaphandle kokubhubhisa izinhlobo ezahlukene imikhomo kanye nokunciphisa inani lazo. Nokho, yilokho kuphela ongasitshela mayelana imikhomo ngokwehlukahlukana kwabo kwezinhlobo. Iningi lawo abantu izilwane ezinokuthula ukuthi thukela ukuhlasela umuntu.
