Keith - hove kana mhuka? mubvunzo uyu kutambudzika masayendisiti asati veMubatanidzwa nesayenzi yemazuva ano. Zvikurukuru, dambudziko iri aiedza kusarudza zvakadaro shasha pfungwa imwe, sezvo Aristotle. Uye saka akasvika chete mhedziso kuti venguva yedu. Asi ngatirege zvose kuitira.

Keith - ichi ndicho chinonyanya noumambo vagari mvura chokudenga. With ukuru hwaro uye nyasha unmatched nokuda chisikwa chipenyu chipi, tisingatauri mano ake zvinoshamisa kuti nziyo. Asi chii chimwezve Tinoziva pamusoro zvisikwa izvi incredible?

Ndiani shato huru?

Saka chii zvinoreva shato huru? Maererano duramazwi, huru mhuka kuti anogara mugungwa. Ndiko kuti, mukusiyana zvakapfuura, kuwana mhinduro yakadaro tangled nyaya nyore. Asi sei zvichaitika kuti muzukuru ane shato huru yekare vaida kuchinjana nyika mugungwa?

Zvakanaka, chokwadi chose, masayendisiti achiri handizivi. Zvisinei, zvinozivikanwa kuti makore mamiriyoni 60 akapfuura madzitateguru cetaceans zvose, kutanga akaenda kunotsvaka kwavo zvokudya shure mumvura. Zvichida ichi kwakaita kuti kwenguva refu kwemvura, izvo akaparadza chikamu zvinomera panyika, kana yakawanda makwikwi nevamwe mhuka. Asi chokwadi chinoramba - madzitateguru hove huru ndisisadi kudzokera kunyika.

Sei mhuka Nyika dzakashandisa upenyu mumvura?

Zvinofanira kunzwisiswa kuti yakadaro metamorphosis hariwaniki imwe kana maviri. Shanduka - ari ngetani kuchinja duku kuti kwezviuru zvemakore muviri mhenyu iri kuramba kusachinja. Izvi pakupedzisira anobereka hutsva rose, Evhangeri yemvura noMweya ndiyo madzitateguru ayo.

Asi pashure pemakore mamiriyoni 60, vatsvakurudzi achiri kuwanikwa shato huru marangwanda mamiriro Zvisaririra ivavo vekare, wakati akafamba pamusoro ayo mana netsoka dzakapfava panyika. Somuenzaniso, iye ane hudyu pfupa, riri kurutivi rwemberi chikamu muviri. Uyewo, ayo zvimbi pamberi zvakafanana mapfupa mamiriro noruzhinji mhuka zvinetsoka hoofed.

Apedza nhamba yezvidzidzo, masayendisiti kusvika kuziva mhedziso. Zvakaratidza kuti dzepedyo nehama cetaceans vari mvuu. Uye kana iwe kunyatsotarisa, zvimwe zvakafanana maitiro avo vanogona kuonekwa kunyange nhasi. Akanyanya kwavo kukuru chido mvura.

Mhuri Cetaceans

Zvinofanira kucherechedzwa kuti shato huru - hakusi mumiririri chete nemhuri yake. Dolphins uye porpoises zvinosanganisirwawo muchikwata che zvomumvura mhuka. Sei vakasiyana nevamwe vagari mvura yakadzika?

• Chekutanga, zvose hove huru dziri ushamwari-ropa rechiJudha chairo, kusiyana hove. Ndokusaka zviri zvikuru vanoda munhu mafuta muviri wakanaka kuti anogona kuvadzivirira kubva chando pamusoro pemvura umambo.
• Chechipiri, mhuri iyi haisi kukwanisa dzokubvisa okisijeni kubva mvura. Saka, vanofanira nguva dzose kuuya pamusoro, kuti muzadze zvitengeswa rake mhepo mumapapu.
• Chechitatu, ivo zvokudya vana vavo mukaka. Kunyange kwemakore shanduka uyu muitiro chinguva ichigadziriswa, cetaceans zvichiri mhuka.

Mhuri yose rakakamurwa mapoka makuru matatu:

• Baleen hove huru (Mysticeti) - chikuru yokuzviparadzanisa mhuri. Its runoratidza chinokosha Sefa muviri "whalebone", riri pamusoro yokumusoro rushaya hwemhuka. Its chikuru basa - inonzwika apo plankton pakusachena ndisingadiwi.
• Toothed hove huru (Odontoceti) - uye zvikara makuru, preying pamusoro Squid uye nehove diki. Miti iyi anokwanisa kufamba mumvura uchishandisa echolocation.
• Ancient hove huru (Archaeoceti) - zvinosuruvarisa hapana mumiririri kuroorwa muchikwata ichi, vasingagoni kurarama mazuva edu.

Hove huru: mukuru ruzivo

Pakati vose vagere kweNyika shato huru - chikuru mhuka. Paavhareji mukuru wacho anogona kusvika 25 metres kureba. Enzanisa nehasha chete kutora mabhazi makuru 4, kana vakaisa pamusara. Hazvishamisi kuti chinhu chikuru chakadai hunorema anenge 90-110 matani, uye vamwe kunyange zvakawanda.

Hofori idzi kurarama anenge ose nyanza yose nyika. Chokwadi, vanogona tama panzvimbo imwe neimwe zvichienderana nemwaka. maitiro Izvi imhaka yokuti hove huru dziri nehanya mvura tembiricha, uye saka muchando vanopedza pedyo dzinopisa.

Yose zvayo, pakati vose vemhuri iyi zvinogona kupatsanurwa maviri akasiyana subspecies: zvitema uye vachena hove huru. Kazhinji, kupesana uku imhaka noruvara ganda mhuka idzi, asi pane dzimwe, kusawirirana hakukoshi.

Mashoko anoratidza kare

Gray Whale - ndiye mumiririri mukuru wemhuri. Masayendisiti akawana zvisaririra emhuka idzi ine pachisara aiva nemakore anenge mamiriyoni 30. Kare, Hofori izvi vaigara zvinenge pamakona ose apasi, asi zvino vanogona kuwanikwa chete kuchamhembe chikamu Pacific Ocean.

zvisikwa izvi inoshandiswa kurarama mumapoka maduku kweinenge 2-3 vanhu neimwe. Kunyange zvazvo iwe unogona kazhinji kusangana, uye oga shato huru muchizvikudza achirima mvura dzezvimwe. Asi vakawanda Hofori vanosarudza kurarama boka. Kazhinji ichi ndicho nokuti kuti vachena shato huru iri chaizvo yakatanga zvakasimba ukama hwemhuri.

Zvimwe zviri kushamwaridzana ichi rakavabatsira vapone nguva ngozi. Pashure pezvose, vari pakati XX remakore Vakaparadza anenge zvachose whalers, vachivhima dzavo mafuta. Saka, maererano masayendisiti, muna 1946 nhamba mhuka idzi wacho wakaderedzwa kusvika vanhu 250. Bedzi chishamiso, uye nokuedza kodzero mhuka kurovedzera akakwanisa kunzvenga njodzi. Zvino uwandu mhuka idzi yawedzera 30 zviuru., Kuti akavapa tariro itsva ramangwana riri nani.

Blue Whale - chikuru chisikwa panyika

Kana rwebhuruu hove huru, ivo vaiona kuti zvisikwa pakukura ino. Kunyange mhuka yakakura kudaro sezvinoita nzou, asingakwanisi kukwikwidzana navo. hukuru izvi vanoyeuchidzwa kuti kana zvakada nehofori akafamba pepasi Pasi. Zvino, blue whale - mumiriri chete vekare mhuka hofori.

Mhuka iyi haisi kunyanya kukuchidzira vanhu, uye saka kashoma anosvika pamhenderekedzo. kufarira svikiro rake penyanza rakavhurika, apo anonzwa zvechokwadi akasununguka. Anobvisa zvisanduke, chete chete kumhanya 10-12 km / h, asi pakaita zvinogona kuwedzera matanhatu navatatu.

Kufanana nhengo zvose zvipenyu ake, blue whale unodya plankton. Uye kunyange mhuka iyi kare kwakatsiva nyika pamusoro pemvura, kuti mairi, unogona zvakadaro kwete. Ndokusaka hove huru kazhinji kuyangarara pamusoro pemvura, nokudaro kusunungura mvura kubva zvitubu hwomukova chaiyo iri yokumusoro muviri.

kubereka hove huru

Hove huru - mhuka gungwa, vane nhamba kazhinji airarama nemafashamo nhanho. Izvi kunobva kuvanhu vachivhima nyama yavo uye mafuta. Zviri ivo vari honzeri ava matambudziko makuru, asi kwete chete.

Chimwe kukanganisa vanhu chero rudzi, kukwanisa kwayo zvichiberekana. Saka dambudziko iri chokwadi kuti zvisikwa izvi vanotungamira mwana akaberekwa asina kupfuura kamwe mumwe kana vaviri makore. Uye apo nehadzi anobereka shoma shato huru imwe chete, dzinenge - maviri. Panguva iyoyowo, zvichienderana subspecies hove huru nhumbu anogona kugara pakati 9 uye 18 mwedzi.

Pleasant ndechokuti amai nguva dzose hanya vayo. Avo, akavapindurawo, kukura nokukurumidza uye kuwedzera uremu. Saka, paavhareji, pazuva shorthead angawana vanenge 50 makirogiramu ose mhenyu uremu. Saka usashamisika kuti vamwe mwedzi minomwe, anogona vymahal kusvika 14 metres urefu uye vanoyera 20-25 matani apo.
