Iyisilwane esisengozini: ihlengethwa emfuleni IsiShayina (baijiu)

Ngo-1918, into ezithakazelisayo itholiwe kwelinye amachibi angenasawoti kwezindaba zesifunda Chinese Hunan. I Dongting Lake waphawula esincelisayo zasemanzini kungokwalabo suborder kwemikhomo toothed. Baqamba igama lakhe ngokuthi lesi silwane "Chinese emfuleni ihlengethwa."

Ngobani emfuleni amahlengethwa

Abantu zisetshenziselwa yokuthi amahlengethwa - izakhamuzi ulwandle futhi ulwandle amanzi anosawoti. Kodwa kukhona umndeni encane osesikhundleni River amahlengethwa. Namuhla kukhona 4 zezilwane ezincelisayo Cetacean. Ezintathu kuzo bahlala amanzi ahlanzekile, kanti owesine bangaphila emifuleni nasemachibini amaningi futhi olwandle. Ngeshwa, le ezisengozini zilwane. They jeza ngenxa ukusondela nabantu. Ezingasekho ngenxa ukungcoliswa yemifula nokuzingela engalawuliwe.

Yini exhumene igama

abantu bendawo basibiza ngokuthi emfuleni esincelisayo "baijiu". IsiShayina emfuleni ihlengethwa has a ehlukile kakhulu amaphiko fin, efana ebhokisini isheke. Yilokhu awunika igama eyayivame ukusetshenziswa kwezinhlobo. Igama yezesayensi kwezinhlobo - Lipotes vexillifer. Luhilela imiqondo emibili. Leipo isho "ukhohlwe" futhi vexillifer - «abathwele ifulege". Njengoba ubona, abacwaningi futhi wasebenzisa Association zangaphandle lapho ngiphakamisa igama kwezinhlobo ngamanani amancane esincelisayo.

Incazelo zezinto eziphilayo

Amachibi kuvakashe ummeleli wendlunkulu imikhomo toothed, amaShayina emfuleni ihlengethwa - impela isilwane esikhulu. Ubuningi eqoshiwe mammalian obuphelele ndikimba 2.5 m kanye nobude ubuncane omdala - .. 1.5 m Isisindo omdala isilwane zingaba phakathi 100 kuya 160 kg. Incazelo ihlengethwa akuyona imininingwane kakhulu. Kuyaziwa ukuthi izinsikazi kwalesi silwane zinkulu futhi idlule usayizi kwabesilisa. NgoLwesine kutholakale isidumbu sendoda ihlengethwa aminyene futhi esiyisigqigqi. Intamo kuyinto ngempela ephathekayo. Amaphiko pectoral abe base ebanzi, kodwa ku-edge sengathi sinqunyiwe ngembazo. Amaphiko fin usayizi ibhokisi-Ngokwesilinganiso, nge front ngokushelela watsheka futhi imiphetho labaqaphi elingemuva. Itholakala hhayi phakathi emuva, futhi eduze esigabeni umsila.

Esisogwini umqhele esincelisayo okusaqanda blowhole. It is kancane saya ngakwesokhohlo kusukela maphakathi. IsiShayina emfuleni ihlengethwa kabi ubona. Amehlo akhe kungukuthi athuthukiswe kahle futhi kunalokho kahle elise. Ziyakwazi okusezingeni eliphezulu ekhanda, esehlisa engela wokubuka.

Ngaphambili ingxenye Nogebhezi lwawo - okubizwa ngokuthi ngisesiteji, ke lincane side. It is kancane ibheke phezulu, futhi ungathi Uqhwaku lwenhlanzi okuthiwa i crane. I ongenhla sinamazinyo abangaphansi kuka-phansi. Max phezulu - 68 namazinyo, futhi phansi - 72 namazinyo.

Akunakwenzeka ukubhala incazelo dolphin, hhayi ecacisa umbala isilwane. Baijiu ukukhanya blue noma bluish-grey tint. Sisu izilwane emhlophe. Nakuba abanye ofakazi bathi umbala ulula kakhulu kunezinye incazelo esemthethweni. Bathi emfuleni Chinese Dolphin cishe emhlophe.

Ukusatshalaliswa zinhlobo

Ngokuvamile lolu hlobo emfuleni amahlengethwa wahlangana eMfuleni umfula iYangtze. Uma uke wazibona, kubukeka sengathi eMfuleni umfula iYangtze kumephu, bese ubona ngeso lengqondo ukuthi kwenzeke kanjani ukuba ejulile Umthambo omude kunayo yonke. ubude bayo idlula 6300 km, kodwa akazange ugcine Chinese emfuleni ihlengethwa ekuqothulweni usongo. Ngezikhathi ezithile lezi ezincelisayo elalihlangana Tsyantane (River) kanye namachibi of Dongting futhi Poyang. Omunye umuntu livele endaweni Shanghai.

Kanjani ukuphila futhi yini uhlobo izifunzo

Tadisha ukuphila yalolu hlobo kunzima kakhulu. Ngenxa izinombolo ezincane, kukhona cishe awekho ulwazi. Esikwaziyo ukuthi umfula amahlengethwa agcinwa ngazimbili kanye uthanda zemifula kanye emanzini angajulile angasogwini. Cishe, lokhu imbangela ukuthuthukiswa abampofu kwezitho kwezinhlobo. Amanzi uhlale ezinodaka, ngakho iso empeleni engenamsebenzi ancike amaza omsindo.

IsiShayina emfuleni ihlengethwa kuyindlela yokuphila yansuku zonke. Ebusuku ezikhoselweni ezindaweni nge flow kancane, ukuze uphumule.

Ekudleni esincelisayo encane inhlanzi, eels, eyikati futhi clams. Ukuze nokuzingela isilwane isebenzisa uqhwaku eside. Ngalo Ukuvubukula ihlengethwa zokukhiqiza kodaka. Ngenxa yokuchoboza komuntu amagobolondo kanzima usebenzisa amazinyo ngokukhethekile bazivumelanisa ngalezi zinhloso.

Ngezikhathi ezithile emfuleni amahlengethwa ubuthe amaqembu. iqembu okunjalo kungase kuhilele 3 ngabanye, futhi kungaba Inani 15 izilwane. Kodwa lezi zakhiwo akuzona ezimi njalo.

ukukhiqizwa kabusha

Mayelana ukukhiqizwa kabusha Chinese emfuleni amahlengethwa ukwaziswa okuncane kakhulu. Ososayensi baye wasikisela, ngokusekelwe idatha kusuka okusanhlamvu atholakale nabo izingalo zabo. Abesifazane akuzona uvundile impela. Baletha kwenye cub, futhi akukho kanengi ukudlula kanye njalo eminyakeni emi-2. Cishe, inkathi sokukhulelwa izinyanga 11. Cubs bazalwa ayinamandla. Isikhathi sokuqala umama anayo ukuzigcina uqinile nge amaphiko abo.

Isikhathi ngqo zokuthomba alwaziwa. Ngokusho ezicatshangwayo, kungaba phakathi iminyaka emithathu eziyisishiyagalombili.

Imizamo ukulondoloza zilwane

Yiqiniso, ososayensi bazama ukulondoloza ezisengozini yokuqothulwa kwezilwane, kodwa kwaba njalo endabeni ka China ayikwazanga ukufinyelelwa ngasemfuleni ihlengethwa impumelelo. Naphezu kweqiniso lokuthi lezi zinhlobo ivikelwe futhi ohlwini ezisengozini, izilwane nemvelo empeleni kwesokunxele. ubufakazi Yamuva kulo mhlangano abadobi ihlengethwa ukubukwa eyatholakala ngo-2004 Ngo-2007, lowo mkhankaso wathunyelwa ukuqoqa inani elithile okuphambene-ubulili abantu (mayelana 25 amakhanda). Lokhu kungase kuvumele uhlelo ukubukwa okusakazwa ekuthunjweni futhi ngokwengxenye ukubuyisela labantu. Kodwa lo mkhankaso babuya lutho. imishini yanamuhla iye akubhalwa baijiu. Lokhu kuholela esiphethweni sad: labantu emfuleni amahlengethwa wafa futhi ulibuyise ngeke zisebenze. Ngokudabukisayo ungaqondi, kodwa amaShayina emfuleni ihlengethwa is yaqashelwa ngokomthetho njengezwe yokuqothulwa kusukela ngo-2007.
