Mhuka huru yegungwa pasi rose Inogona kuyera kusvika ku 30 metres kureba uye kurema pamusoro pematani mazana maviri. Izvi zvinoita kuti mhuka iyi isangova hombe chete asiwo inorema zvikuru mugungwa.
Kana iwe uchida kuziva kuti mhuka iyi chii, usapotsa chinyorwa chatakagadzirira nezvazvo, uye kupi, kuwedzera, Tichataura pamusoro pekuti ndedzipi mhuka huru panyika.
Mhuka huru yegungwa pasi rose
Vazhinji vangasashamiswa kuziva kuti mhuka hurusa yomugungwa munyika iwhale. Zvikurukuru ndizvo bhuruu whale (Balaenoptera musculus). Tinogona kutaura pamusoro payo kuti imhuka hurusa, kwete bedzi mugungwa asi papasi rose. Hurefu hwayo huri pakati pe 24 ne 27 metres asi zvienzaniso zvakawanikwa zvasvika 30 metres. Kuti uwane pfungwa yehukuru hweblue whales, Hukuru hwayo hwakakura kupfuura hwendege inotengeswa uye rurimi rwayo runogona kurema zvakafanana nenzou, iyo iri imwe yemhuka hurusa munyika.
Pasinei nehukuru hwakadaro, blue whales ane hushamwari uye hunhu hune rugare. Vanogona kuonekwa vachituhwina mumapoka emhuri kana dzimwe nguva vari voga vachitsvaka zvokudya. Rwiyo rwavo, pasina kupokana, humwe hwemhando yemakungwa, ine mafambiro anogona kunzwika kubva kumazana emakiromita kure.
The blue whale uye nhoroondo yayo panyika
Blue whales dzave dzichigara mumakungwa ePasi kwemamiriyoni emakore, apo madzitateguru avo akashanduka kubva kumhuka dzepanyika kuenda kumhuka dzemvura. Zvinotendwa kuti ndiko kwakabva blue whale, mhuka yakashanduka kuti ienderane nehupenyu mugungwa, kuva, zvose nokuda kwekukura kwayo uye ruvara, imwe yemhuka dzinoshamisa zvikuru mumakungwa.
Blue whale yakaita sei?
Blue whale imhuka yemugungwa inoyamwisa inowanikwa mumakungwa ose epasi uye inodya ma<em>crustaceans madiki nehove. Yakanga ichimbove munjodzi huru yekutsakatika nekuda kwekuvhima kusingasaruri kwekutengesa kwezvigadzirwa zvakatorwa kubva kwavari. The Whale Izvo zvakakosha pakuchengetedza kuenzana kweiyo marine ecosystem. Unogona kuverenga zvakawanda nezve njodzi dzinotarisana nemawhale Parizvino.
Zvokudya
Mukati memakore anoda kusvika mamiriyoni makumi maviri ayo mawhale anofamba mumakungwa, akazvipira kuvhima zvokudya. Yake kudya kunobva pane diki crustacean inonzi krill, kunyange zvazvo vachidyawo hove duku uye squid. Kuti vabate mhuka idzi vanoita izvo zvinozivikanwa se "sefa yekudyisa", Hove dzeblue whale dzinonyura mumvura yakadzika uye dzinoshambira dzakashama miromo, dzichiunganidza mvura yakawanda pane mhuka idzi. Inobva yavhara muromo wayo yoburitsa mvura nemubhareen yayo kuti ichengetedze chikafu. Nemhando iyi yekuvhima, vanodya zvinosvika matani mana echikafu pazuva. Kunyange zvazvo iri mhuka huru uye inorema kudarika dzose, inotuhwina ichimhanya zvikuru, izvo zvinoita kuti ibate zvokudya zvose izvi. Kana iwe uchida kudzidza zvakawanda nezvekudya kwehofori idzi, tarisa chinyorwa pa zvinodyiwa nemawhale.
Kuvhima
Munhau yose, blue whale yave ichivhimwa zvikuru nevanhu. Muzana remakore rechi19 ne20, Vakatambudzwa zvakanyanya kuti vawane nyama, mafuta uye zvimwe zvigadzirwa. Nekuda kweizvozvo, huwandu hwemienzaniso hwakaderedzwa zvakanyanya. Kuti izvi zvisanyanya kuipa, muna 1960 kuvhimwa kwemhuka idzi kwakarambidzwa. Chii chimwe, nhasi, Blue whales inodzivirirwa nemitemo uye zvibvumirano zvepasi rose, saka nhamba yezvienzaniso yakawedzera zvakanyanya mune dzimwe nzvimbo.
Ichokwadi zvakare kuti blue whales Havasati vabuda zvachose munjodzi, sezvo pachine tyisidziro kuupenyu hwavo, zvakadai sokusvibiswa kwegungwa, kuchinja kwemamiriro okunze, uye kunyange ngarava dziri kubonderana nazvo. Mukuwedzera, nzvimbo dzakachengetedzwa dzegungwa dzakatangwa kuti dzipe mhuka idzi nzvimbo yakachengeteka mugungwa. Matura emvura aya ane mabasa mashoma evanhu kuitira kuchengetedza whale nedzimwe mhuka dzinenge dzava mungozi. Kuti uwane rumwe ruzivo nezve mitemo inochengetedza zvisikwa izvi, unogona kushanyira webhusaiti mhando dzewhale izvo zviripo.
Kukosha kwaro kunyika yegungwa
Nyeredzi dzakakosha pakuchengetedza marine ecosystem nekuda kwezvikonzero zvakasiyana. Kutanga, ivo ndivo vanotonga kana kudzora huwandu hwekrill (chikafu chavo chikuru). Kana vakanyangarika, huwandu hwekrill hwaizove husingadzoreki uye hwaizokanganisa ecosystem. Kune rumwe rutivi, kushandiswa kwekrill kunoita kuti vasunungure zvakawanda zvakakosha zvekudya kuburikidza netsvina yavo kuitira kuti nhamba huru yemiti yegungwa uye phytoplankton inogona kukura. Zvose izvi zvinozviita mhuka yakakosha yecheni yekudya mumakungwa.
Sokunge zviri pamusoro apa hazvina kukwana, kubatsira kutenderera kwekabhoni sezvo vachitora carbon dioxide yakawanda kubva mumhepo uye vachiichengeta munyama yavo. Patinofa, kabhoni iyoyo inoenda pasi pegungwa. Izvo zvakakosha kuti tinzwisise kubatana kwezvipuka izvi nezvisikwa zvemugungwa kuti titende basa razvo munharaunda, musoro unotariswa zvakadzama muchinyorwa che. mhuka dzemugungwa.
Mhuka gumi dzakakura kwazvo munyika
