A whale huru kubva kumhuri yehawende

Smooth (chaiyo) nyangadzi dzakawanda zvikuru, dzinokambaira uye dzine mhuka dzakakura-dzichi, dzichirima makungwa epasi redu. Zita remhuri yavo ndeyekusavapo pamutsipa uye mudumbu zvemarudzi ose emapoka nemigero, izvo zvinoita kuti muviri usanyatsonaka. Parizvino, mhuri yei giants iri ine marudzi maviri nemarudzi mana. IWhale yakawanda kubva kumhuri yefigiro yakanyatsonaka yeGetlandic. Funga nezvemhuka idzi dzegungwa nemashoko akawanda.

Kugadziriswa kwemapapiro akanyatsonaka

Usati watanga nhoroondo yacho, zvinonzwisisika kunyora vose vamiri vemhuri. Uyezve, hakuna zvakawanda zvezvo. Vadzidzi veZoologist vanoparadzanisa mhuka idzi dzegungwa mumatare maviri chete. Mhando yekutanga-mutsvuku-inomiririra-inomiririrwa nemhando imwechete chete ine zita rimwe chete. Yechipiri - nyangadzi dzemaodzanyemba - dzinomiririrwa nemarudzi matatu: kuchamhembe, kumaodzanyemba uye kuJapan. Zvinoshuva kuti maitiro eGreenlandic polar whales pamugumo weMiocene uye kutanga kwePleistocene yaimiririrwa nemarudzi mashanu akasiyana siyana. Zvinyorwa zvavo zvakawanikwa muNorth America uye muEurope.

Mhuri Tsanangudzo

Sezvatotaurwa pamusoro apa, vamiririri vemhuri iyi vane makuru uye makuru makuru ane musoro mukuru. Murefu, mhuka idzi dzinogona kusvika kusvika 18, uye dzimwe nguva kusvika mamita 22. Kurema kwavo kunopararira kubva pamakumi matatu kusvika zana. Kazhinji ikoko kune vanhu 15 mamita refu. Muviri weiyi minyunguduka yakaoma uye inonatsika pasi. Havana chero mapepa ekureba uye mihoronga, iyo yavakaparadzaniswa nayo mumhuri inofanana. Mhemberero dzemhuka idzi dzakapfupika, asi dzakadzika, uye muromo wemuromo unopfupika, asi wakakwirira.

Vanogara kupi?

Vamiririri vemhuri yefafete huru vanogara zvikuru mumvura yegungwa, vanogara muPacific, Atlantic neActic Ocean. Semuenzaniso, kuchamhembe kwebusina whale kunogara mumvura yeAtlantic. Shamwari yake yeJapan inogona kuwanikwa kumativi ose ekumusoro kwePacific Ocean. Mhuka dzekumaodzanyemba dzeva cetacean idzi dzinoparadzirwa mumvura inotonhorera uye ine mvura yakadzika yeSouth Africa yenyika . Imwe whale huru kubva kumhuri yemapapiro akanyorova, Greenlandic polar, inofarira mvura inotonhora yeNorthern Hemisphere. Nzvimbo yayo inobatanidzwa zvakananga nechando chinopenya ipapo.

Mararamiro ehupenyu anotenderera

Kwete kare kare, vazivi vezvinyorwa vakazoziva kuti vamiri vemhuri iyi vanosarudza kugara vari voga. Kazhinji vanopinda mumapoka ane 4-5 vanhu, asi kwete kupfuura izvozvo. Mapoka ezvinyorwa izvi anowanikwa munzvimbo dzakanyanya kugadzirwa kwezvokudya. Zvikepe zvikuru zvinoputika zviri pedyo nepamusoro pemvura.

Masayendisiti anotsanangura nzira yekudyisa nyuchi dzisina kufara sechinhu chinonakidza uye chisingajaiwi: panguva yekudya kwavo vanoshambira rwonzi nemiromo yakazaruka uye, sevanomesa vacuum, vanomwa mumarudzi ose emagustaceans, plankton nezvimwe zvisikwa zvipenyu. Iko yakasvibira yakawanda ye-subcutaneous mafuta inonyanya kunetsa kupisa kunopisa mumuviri wezvisikwa izvi, saka havasati vashambira mumvura inopisa.

Smooth whales, kufanana nedzimwe mimwe cetaceans, ndeye viviparous zvipfuwo. Mune mamwe mazwi, havangobereki kubereka vana, asiwo vadye nemukaka! Ndosaka zvakakanganisika kutenda kuti mahave ndehove. Nenzira, mukaka whale wechipfumbamwe unowedzera katatu kune mukaka wemhou. Ndosaka zvidiki zviduku zvakakura nokukurumidza.

Mambo wemhuri

Greenlandic polar whale ndiyo yakawanda yezvipfuwo zvose mumhuri inomiririrwa. Sezvataurwa pamusoro apa, uyu ndiye chete anomiririra zita rimwe chete. Ndivo vemuganhu wehaw baleha. Parizvino, ndeyechokwadi unozivikanwa kuti urefu hurefu hwemuviri weyi giant unokwanisa kusvika mamita 22. Muchiitiko ichi, vakadzi vanowanzokwirira kupfuura varume. Kurema kwezvipembenene izvi zvinosvika pamasendi makumi mapfumbamwe nemakumi mashanu. Greenland whales ndiyo dzakasiyana siyana. Vanogona kutama nyore nyore kusvika pakadzika mamita 200 uye vanogara imomo kwemaminitsi makumi mana. Mavhareji ekufambisa kwekufamba kwemakumbo emakungwa makumi maviri nemashanu.

A whale guru kubva kumhuri yeferefere - rekodzero yekutarisira hupenyu pakati pemakumbo. Irojireji yemakore makumi mana, asi izvi hazvirevi. Masayendisiti anotaura kuti mumwe munhu anoponesa kusvika makore 211! Izvi chaizvoizvo zvakanyorwa!

Nzira uye chii icho mhou dzomukati dzinodya?

Nheyo yezvokudya zvei giants ndiyo plankton - zvokudya zvavanoda. IGreenlandic polar whale inofarira kudya zviduku zvishoma (semuenzaniso, mhanje) uye fodder mollusks. Mhuka dzomunhu mukuru dzinopedza kusvika pamatani maviri epa plankton pazuva! Kudyarwa kwemhuka idzi hakusiyana neyevamwe vamiririri ve-suborder ye baleha whales. Izvi zvinobatsirwa neainzi inonzi whale inobata mumasaya ezvimwe zvipfeko zvakanamatira. Mumwe munhu anogona kuva nezvikamu zvitatu kusvika ku 370. Kureba kweplate rimwe nerimwe kusvika kusvika mamita mana.

Kufanana nehama dzayo dzose, whale huru kubva kumhuri yakasvibiswa mukugadzirisa kudya inofamba nemuromo wakazaruka mumutsetsi wemvura, ichicheka nemasimba ayo ane simba uye guru. Iye, se giant vacuum cleaner, anozvibatanidza pachake zvose zvinopinda mumugwagwa wake. Apa ndipo paanoita firimu yake chaiyo, whalebone, inoshanda. Crustaceans vanogara pamahombekiti makuru eamacheta aya, mushure mekunge zvisingatauri kubudisa rurimi uye kumedza. Chimiro chakaisvonaka cheplateti dzakadaro chinobvumira kuti nyama yakasvibiswa ichinyungudze kunze kwema crustaceans, iyo nekuda kwehukuru hwavo inogona kusakwanika kune dzimwe nyundo.

Pamugumo wekupera

Vamiriri vemhuri yeva cetaceans vakanga vakanyanya kuparadzwa nevanhu kare kare kusati kwavandudzwa kwehutachiona. Uye zvose nokuti maruva akanyorova akaoma kubata: vanogara mumvura yepamusoro-soro, gara pedyo negungwa. Mukuwedzera, ivo vanonoka uye vane usimbe. Zvinosuruvarisa, panguva ino nhamba yezvipfu izvi zvinodzinga zvakawanda zvingadiwa. Somuenzaniso, kumaodzanyemba whale inomiririrwa nevanhu 7000, uye kuchamhembe whale kunomiririrwa nevanhu 300. Mahombekombe echiJapane kazhinji akanga asina vanhu vanopfuura 200.

Nzvimbo dzemuNorth uye dzeJapan dzakanyorwa muRubhuku Rurefu semhando dzengozi. Vagari vehama dzavo dzekumaodzanyemba, nerufaro, zvishoma nezvishoma vanodzoka. Kuda kwakadaro kwakanyanya kune mahombekombe aya kunokonzerwa nekukwanisa kwekutakura kwavo. Ichokwadi ndechokuti huwandu hwakawanda hwehutsetse hwemafuta hahubvumiri mhuka kuti iurawe neawulers kuti idire mumvura - iyo nyamusi inoramba ichitsvaira pamusoro pemvura.
