chitarisiko

Hove huru - the mhuka huru vari kupararira munyika yose. Hofori idzi dzinowanikwa mumakungwa zvose, zvose ushamwari uye kuchitonhora. Chichiitwa chitarisiko chavo rakakura saizi. Saka, blue whale ndiyo mhando kupfuura cetaceans. Inogona kusvika kureba pamusoro 30 metres uye vanoyera sezvamakaropafadzwa matani 150. Asi panova rudzi, kukura izvo haapfuuri 2 mamita.

The dzinonakidza ndechokuti musoro shato huru ndiyo huru uye kunosvika 1/3 pakati Kureba muviri. Mutsipa ipfupi chaizvo uye haisi kuonekwa nevamwe. Izvi zvinomutsa mubvunzo: chii chiri kufema shato huru, kana akanga ane mhino yakaita mhuka dzose? Zvakaratidza ndipo. Mumusoro, kana panzvimbo yacho zvakakwirira chikamu, yaiva imwe kufema buri. Ndinofanira kutaura kuti toothed hove huru mumusoro chete pamhino rimwe, ukuwo baleen hove huru - maviri. Tose rangarirai mufananidzo, iro rinotsanangura shato huru ine chitubu pamusoro musoro wako. Saka Tsime iri inoumbwa shato huru nedzinovengwa nyoro mhepo, uye chimiro reTsime anogona muwanikwe cetaceans mhando.

Chimwe kunopindirana Whale - ndiyo kuvapo flippers simba. Uye siyana kwemarudzi dzinosiyana kukura. Nyaya iyi dzinovabvumira kukudziridza wandei nokukurumidza uye anopa kwazvo maneuverability. Chii kunakidza ndechokuti humpback hove huru dzine kupfuura pectoral zvimbi akafanana hofori mapapiro. A nokurohwa yebhuruu shato huru muswe anogona kunyura chikepe nyore.

STRUCTURAL zvinhu

Chimwe runoratidza ndechokuti shato huru - mhuka ushamwari-ropa rechiJudha chairo, mukusiyana vose vamwe vagere mumakungwa. Izvi anotsanangura chokwadi kuti anogona kurarama mumakungwa zvose, zvisinei ambient tembiricha. Huge nuna rukoko kuti vamwe shato huru inosvika 1 meter, inodzivirirawo mhuka kubva hypothermia. Sezvineiwo, zviri muswe kuti mafuta haisi, uye ichi anotsanangura chokwadi chokuti shato huru haasi overheat, apo ari kudziya dzinopisa mvura.

Uyewo akasiyana uye uropi nemhuka. The Ungangove mune cetaceans kunzwa. Munhu wose ajaira chokuti nziyo shato huru inogona kunzwika kure vemakumi makiromita. Vanewo yakanaka echolocation, uhwo Hofori mukuru kutaura, uye kuvhima uye kufamba mumvura. Vision ivowo dzakabudirira kwazvo. With unodzivirira chinowanika zvinoberekwa mamwe omumuviri Kit kukwanisa kuona zvakajeka pasi mvura. All dzimwe pfungwa dzinokudziridzwa asi havaratidzi.

System respiratoria ine maitiro ayo: chiedza hove huru havana chokuita dokeriro. Saka, kana Kufema haana yakamedza mvura. The nasal mawindo vari pamusoro musoro, chokuita mumapapu. Asi shato huru iri kufema mumvura? Mhinduro iri nyore: akaita mhuka dzose, pasi pemvura, Muruvoko mweya wake. mumhino dzake akavhara kana kunyudzwa akafanana mavharuvhu. Uropi anoudza muviri kuti kutendeuka vorudzii upfumi muoti, apo okisijeni iri vaipa chete kune mwoyo uye pfungwa. Izvi zvinoita shato huru kuti svetuka kuti kudzika 2000 mamita.

Baleen hove huru Tidzidze plankton diki kana hove diki rinouya nzira yavo. An nzira dzinonakidza nokudya mhuka idzi. Keith anoratidza muromo huru uye Inomedza zvakadzama pamwe guru yakawanda mvura. Zvadaro, kurishandisa somunhu mutauro hofori pisitoni anomhanyira panze mvura akarova zvokudya anoramba mukati muromo, pasina unopfuura napo ndebvu. Nenzira iyi, shato huru unoparadza pazuva matani 6 plankton.

toothed hove huru

Sezvo munhu wose anonzwisisa yokuzviparadzanisa ichi ane unopinza mazino. In neimwe mhando, ivo vakasiyana pakukura namaumbirwo. chikamu ichi zvinosanganisira dzisingaoneki hove huru, muurayi hove huru uye Dolphins. Avo akasiyana kuravira zvavanosarudza. Dolphins Somuenzaniso, kuda kunovhima hove uye hove huru vanosarudza zvokudya zvisimbiso gungwa neshumba. Mbeu hove huru vakafanana mamwe yokuvhima Squid uye cuttlefish, uye ivo svetuka panguva kwazvo pakadzika.

All toothed hove huru dziri vavhimi zvakaisvonaka. muurayi hove huru kazhinji, rinonziwo muurayi hove huru inogona kurwisa guru baleen hove huru. kufarira delicacy vavo mitauro makuru, vose China, vane zvishoma kufarira. Sezvo baleen hove huru nokuda pamwero mukuru zvikuru imhuka oga uye toothed - aifarira kuva nevamwe, kazhinji kacho kurwiswa rini.

Kuberekwa kwemwana

Sezvo shato huru - inodziya-ropa rechiJudha chairo mhuka, uye vaduku vari vavakabereka vakanyatsosvika, wakafanana mhuka dzose. The shato huru iri kufema pakuzvarwa? The mbudzana ari dangwe muswe uye nemhaka amai vane anoita mweya wake wokutanga pavaizvarwa. The remadzimai kufurira kuti pemvura kuti kufema hurongwa basa zvakazara, uye akazarura mapapu, kungofanana muvanhu.

Zvinofadza kuti vaduku kityata zvokudya mukaka. Tine vaviri vakura mammary shwanu, asi shorthead hazvirevi muchayamwa mukaka, sezvinoita mhuka dzose, uye anowana nayo pamwe jekiseni. Pedyo munyatso ndiyo kwegadziriro tsandanyama kuti vaite basa iri. Uyezve, mukaka zvikuru mukobvu uye mafuta, saka kuti mwana ari kuwana uremu nokukurumidza - kusvika makirogiramu 100 pazuva. Amai vane mwana musi pemvura, sezvo mhuru asingagoni asi zvachose pasi mvura. With Kukura shorthead nani ari kushambira uye mitambo yomumvura.

Whale nziyo

Uyewo nzira yakasiyana dzokukurukurirana hove huru. zvisikwa izvi vanokwanisa kuita rokuimba. Kazhinji, avo kuimba ndiko saka zvinopindirana uye yakanaka kuti anogona kunyevenutsa uye kunyange takanga tisisanakidzwi munhu. Zvinofanira kucherechedzwa kuti havasi vose nziyo hofori. Kunyanya kuita izvi vane humpback hove huru, iyo kunyange kunzi nokuimba. Nei mitinhimira yakadaro, harusati kuzivikanwa. Anofungidzirwa muchato uyu nziyo, asi vanogona anosiyana kubva mwaka nemwaka.

Keith fema nyore. Izvi zvinoshamisa gungwa chisikwa, ine vakawanda kujeka zvakavanzika kwatiri. Kusvikira pakati pezana remakore rechi20, mukuru hove huru chete vaparadzwe zvinodiwa vanhu, uye nhasi vakawanda vari kudzivirirwa.
