Nhanganyaya: Mazino pamhuno
Kana tichifunga nezvemazino, tinowanzoafungidzira ari mukanwa memhuka. Zvisinei, dzimwe mhuka dzine mazino pamhino dzadzo, dzinoshanda zvakasiyana-siyana zvakadai sekudzivirira, kuvhima, uye kutaurirana. Mazino aya ishanduko yekushanduka-shanduka yakabatsira mhuka idzi kuti dzirarame munzvimbo dzadzo. Muchinyorwa chino, tichakurukura nezvemhuka nhatu dzine mazino pamhuno dzadzo: narwhal, saiga antelope, uye nyota-nosed mole.
Iyo Narwhal: Iyo yakasarudzika mazino whale
Narwhal ihove ine mazino ari pakati nepakati inogara mumvura dzeActic muCanada, Greenland, neRussia. Chimwe chezvinhu zvinonyanya kusiyanisa narwhal ibwe rakareba, rakatenderera rinobuda kubva pamuromo wayo wepamusoro. Ngono iyi inogona kukura kusvika mamita gumi pakureba uye rinotova zino rakagadziridzwa.
The Narwhal's tusk: Zino rakagadziridzwa
Nzou izino refu, rakati twasu, rineruvara rwenyanga dzenzou rinokura nemuromo wepamusoro wenarwhal. Iyo inoumbwa nepakati core ye dentin, yakakomberedzwa nedhiri ye enamel kunze. Kusiyana nemazino mazhinji, ayo anokura akananga kubva pashaya, narwhal tusk inokura mumhepo, senyanga yeunicorn.
Chinangwa cheNarwhal's tusk: Dziviriro, kuvhima, kutaurirana?
Chinangwa chenarwhal tusk hachisati chanyatsozivikanwa, asi masayendisiti akapa mazano akati wandei. Vamwe vanodavira kuti nhokwe iyi inoshandiswa kudzivirira zvikara, nepo vamwe vachiti inoshandiswa pakuvhima hove kana sechombo chokupaza aizi. Vamwe vaongorori vanotendawo kuti nyanga iyi inogona kushandiswa kutaurirana nemamwe ma narwhals.
Iyo Saiga Antelope: Iyo unicorn yenhambwe
Mhuka inonzi saiga antelope imhuka ine chitarisiko chakasiyana inogara mumafuro eEurasia. Dzinozivikanwa nemhuno yadzo yakasiyana, iyo yakareba uye yakarereka, ine mhino mbiri huru. Mhino yeshiri inonzi saiga antelope inogadzirika yekufema nekutonhodza munzvimbo yadzo inopisa uye yakaoma.
Saiga antelope nose: Kugadziridzwa kwekufema nekutonhodza
Mhuno dzeshiri inonzi saiga antelope dzakagadzirwa kuti dzisefe huruva uye kutonhodza mweya unopisa wadzinofema nadzo. Mhuno dzadzo huru dzinobatsirawo kuti dzinzwe munhuhwi wezvikara zviri kure, zvichiita kuti dzikwanise kuona njodzi dzotiza nekufamba kwenguva.
Saiga antelope mazino: Inoshandiswa kuchera nekudzivirira
Mazino e<em>saiga antelope ari kumberi kwemhino dzavo, pamusoro pemuromo wavo wepamusoro. Aya mazino anoshandiswa kuchera midzi uye machubhu, ayo anoumba chikamu chakakosha chekudya kwavo. Dzinoshandisawo mazino adzo kudzivirira zvikara zvakaita semhumhi nemakondo.
The Star-nosed Mole: Inyanzvi yekubata
Nyeredzi-nosed mole imhuka diki, yakaita semhashu inogara munzvimbo dzine mvura dziri kumabvazuva kweNorth America. Iyo inozivikanwa nemhino yayo yakasarudzika, iyo yakafukidzwa nediki, pink matende akafanana nenyeredzi. Aya matende ane hanya zvikuru kubata uye kubatsira mole kufamba uye kuwana mhuka mumvura ine rima uye yakasviba.
Nyeredzi-nosed mole nose: Inhengo inonzwiwa zvakanyanya
Nyeredzi-nosed mole mhuno inhengo inobata zvakanyanya iyo yakafukidzwa mune zvinopfuura 25,000 sensory receptors. Aya ma receptors anobvumira mole kuti ione kana kudiki-diki kufamba uye kuzununguka mumvura, ichibatsira kuti iwane mhuka dzakabatwa senge tumbuyu, makonye, uye hove diki.
Nyeredzi-nosed mole mazino: Inobatsira nekubata mhuka nekudzivirira
Nyeredzi-nosed mazino emole ari kumberi kwemhino dzayo, pazasi pematende. Mazino aya akapinza uye anonongedza, uye anobatsira mhute kubata nekuuraya mhuka yayo. Dzinoshandisawo mazino adzo kudzivirira zvikara zvakaita senyoka neshiri dzinodya nyama.
Dzimwe mhuka dzine mazino pamhuno
Kuwedzera kune narwhal, saiga antelope, uye star-nosed mole, kune dzimwe mhuka dzakawanda dzine mazino pamhuno dzadzo. Izvi zvinosanganisira shrew-nosed shrew, Hispaniolan solenodon, uye African elephant shrew.
Mhedziso: Mazino pamhino, mukana wekushanduka-shanduka
Mazino pamhino angaita seasinganzwisisike kuchinjika, asi aratidza kuve mukana wekushanduka-shanduka kune mhuka dzakawanda. Kubva panhongonya yemhungu kusvika kumazino emhembwe uye mhuno ine mhuno ine nyenyedzi, kuchinja uku kwakabatsira mhuka idzi kuti dzirarame uye dzibudirire munzvimbo dzadzo.
