Whale yakawanda inoda kuchengetedzwa

Chero ani zvake ari kunyanya kufarira biology anoziva kuti blue whale ndiyo whale huru munyika yose. Mifananidzo nemavhidhiyo iyo iyi nyamadzi yemvura yakanyorwa, nguva dzose inokwezva vataridzi. Mushure mezvose, bhuruu harisi chete guru guru whale. Iye ndiye mhuka huru pane yose iripo pasi pano nhasi. Uye dzimwe paleontologists vanoti ichokwadi chiri mhuka huru pane dzose dzakambovapo panyika yedu. Uye kunyange munguva yemahombekombe makuru, pakanga pasina chimiro chakakura kupfuura hukuru hwayo uye hukuru.

Iyo huru whale, yega, inongomanikidzwa kuva muridzi wezvinyorwa zve chikamu che "most-most". Uye haana kuodza mwoyo. Saka, urongwa hwezvinyorwa zvebhuruu whale: mutauro unonyanya kukosha munyika yose (kusvika kune maita mana), iyo yakawanda yemapapu (zvinopfuura matatu mamita). Uye, maererano nezvimwe zvinofungidzira (zvisinei, zvinonzwisisika zvinoratidzirwa), huwandu hwemapapu hunosvika zviuru gumi nezvitanhatu ... Ngatitii tichienderera mberi: iyo yakawanda yeropa - kusvika pamasere masere elitha, mwoyo wakakura - anenge tani mumakona makuru. Huru hwema whale mumamiriro akadzikama hutanhatu kusvika kune husiku hunomwe paminiti, uye chete mushure mokunge uchishambadza unowedzera kusvika gumi nemaviri.

Mune miniti bluu whale haitore zvinopfuura mana kufema. Anei yakakura zvikuru yemidziyo yeropa: chikamu chedoroal aorta chinosvika pakureba masentimita makumi mana. Wedzera kune iyi mafuta akawanda (blubber), iyo yakawanda mashoma ayo ari chikamu chemazana ose emhuka (uye kunyange zvishoma). Maererano nemishumo yewhalers, vakasangana nemapapiro ane mashekeri zana nemakumi mapfumbamwe nemaviri. Asi kune zvimwe zvishomanana, mhuka dzakawanda hadzikure kusvika pakukura kukuru. Uye kunyange mushure mokunge vasvika pakanyorwa nhamba shomanana yebhuruu whales (zvuru zvishanu) pakati pemakore makumi matanhatu ezana remakore rapfuura, nyaya yacho, nekuda kwekuchengetedzwa kwezvakachengetedzwa, yakapindirana, simba rayo ikozvino rinenge zviuru zvine gumi, iro rinowanzopfuura makore zana nemakumi mashanu Kudzoka. A whale yakakura achiri kudiwa zvakawanda. Uye izvi hazvikwanisi kuregererwa.

Panguva imwecheteyo, whale huru haisi kurega kushamisa nezvimwe zvikamu zvemuviri wemuviri izvo zvisiko kwete kune guru, asi kune mhuka yepakati kana kunyange shoma duku. Semuenzaniso, pharynx ye blue whale ine uwandu hwe ... chete masentimita gumi! Saka, haigoni kumedza kudya kukuru. Whale yakawanda ine zvokudya zvinosanganisira vagari vaduku vegungwa, kunyanya kubva plankton. Mukupfuura, anokwanisa kumedza uye zvimwe zvinhu zviduku zvakaitika zviri pedyo. Mumimba yebhuruu whales, duku squid nehove zvakawanikwa. Kuti kudzivirira mhuka huru dzisapinde mu pharynx, whale inodharira mvura yegungwa nemvura "whalebone" - mitsara yakawanda yemapuleti ehomiti.

Mabhawuru yebhuruu anounza zvishoma nezvishoma. Mukadzi wacho anobereka vana gumi nemwedzi uye anogona kuuya nemwana kana maviri. Iroji yekuberekwa iviri - kwete kupfuura imwe chete. Ukuru hwekondo yakangoberekwa mamita manomwe kusvika masere, uye uwandu hunoita matani maviri kusvika matatu. Mukadzi anodyisa whale nemukaka kusvikira pazera remwedzi minomwe, uye zuva nezuva unogamuchira makumi mapfumbamwe emakiri emuviri wemvura. Imwe nhoroondo!

Kubva muna 1966, mafiroti makuru ezvo akadziviswa kubva kune hove pasi rose. Asi mombe dzavo dziri kukura zvishoma nezvishoma. Uye hazvisi zvokuvhima ivo. Ikoko kukanganisa kwakanyanya kunokonzerwa nokusvibiswa kwezvakatipoteredza. Kuwira mumakwenzi emafuta egungwa kunowedzera mumuviri webhuruu whale whale, ndokuzotamira kune mwana, izvo zvinokanganisa utano hwavo. Pasinei nekukura kwehuwandu hwezvisikwa izvi zvemvura, kuvapo kwemarudzi kuchiri kutyisidzirwa.
