Nhanganyaya: Mazino pamhuno
Kana tichifunga nezvemazino emhuka, tinowanzoafananidza mumuromo. Zvisinei, kune dzimwe mhuka dzine mazino pamhuno dzadzo, izvo zvingaita sezvisinganzwisisiki kwatiri. Aya magadzirirwo anonakidza uye akasiyana, uye anoshanda zvinangwa zvakakosha muumambo hwemhuka.
Iyo Narwhal: Iyo yakasarudzika mazino whale
Nhunyu zvichida ndiyo mhuka inonyanya kuzivikanwa ine mazino pamhuno dzayo. Iyi whale ine mazino inogara mumvura yeArctic yeCanada, Greenland, Norway, neRussia. Manurwhals echirume ane nyanga refu, yakatenderedzwa inogona kukura kusvika mafiti gumi kureba, ukuwo hadzi dzine nyanga pfupi, yakatwasuka. Asi zinzou rakagadzirwa nei, uye nei narwhals vanaro?
Narwhal's tusk: nzou kana zino?
Pasinei nezita rayo, nyanga yemhungu haisi nyanga, asi zino. Yakagadzirwa nenyanga dzenzou, inova rudzi rwezvinhu zvakaoma, zvakakora, uye zvichena zvinowanikwa mumazino nemazino edzimwe mhuka. Nhunga inokura kubva pashaya yepamusoro yenarwhal, uye rinotova zino rakagadziridzwa rinopinza rinogona kubuda nemuromo. Asi nei ma<em>narwhal aine zino iri rakasiyana nemamwe?
Narwhal's tusk: Inoshandiswa pakuvhima kana kutaurirana?
Kwenguva yakareba, vesainzi vaidavira kuti nyanga yenhokwe yainyanya kushandiswa pakuvhima, sezvo yaigona kushandiswa kurovesa hove kana kupaza aizi. Nekudaro, tsvakiridzo ichangoburwa inoratidza kuti tusk inogona zvakare kushandiswa kutaurirana uye magariro. Manurwhals echirume ane mazino marefu anotonga uye anogona kuashandisa kuratidza chimiro chayo kune mamwe marume kana kukwezva hadzi panguva yekubatana.
Nyoka yeNarwhal inogona kukura kwenguva yakareba sei?
Narwhal tusks inogona kukura kusvika 10 tsoka kureba, asi varume vazhinji vane mazino akareba 6-9 tsoka kureba. Madzimai ane mazino mapfupi anowanzoita mafiti matanhatu kureba. Nhunga inokura muhupenyu hwose hwenarwhal, uye inogona kuumba chimiro chakatenderera chakasiyana painokura.
Dzimwe mhuka dzine mazino kumeso
Kunyange zvazvo narwhal zvichida iri mhuka inonyanya kuzivikanwa ine mazino pamhino dzayo, kune dzimwe mhuka dzakawanda dzine izvi zvakasiyana-siyana. Ngatitarisei zvishoma zvacho.
Nyeredzi-Nosed Mole: Mhuno ine 22 matende
Nyeredzi-nosed mole imhuka diki inoyamwisa inogara munzvimbo dzine mvura nemachakwi kuNorth America. Mhino dzayo dzakafukidzwa nematemba ane nyama 22, rimwe nerimwe rine zviuru zvezvinogamuchirwa zvinonzwa zvinogona kuona kubata, tembiricha, uye makemikari. Nyeredzi-mhuno yemhuno inoshandisa mhino yaro kutsvaga nekuona mhuka mumvura ine rima, yakasviba kwainogara.
The Elephant Shrew: Mhuno refu, mazino akapinza
Nzou mhuka imhuka duku, inodya zvipembenene inogara muAfrica. Iine mhino refu, inopfakanyika iyo inoshandisa kuferefeta chikafu muvhu nemarara emashizha. Mhuno yenzou ine mazino akapinza akapinza ayo inoshandisa kubata nekuuraya mhuka yayo.
The Snipe Eel: Mhuno ine mazino ekuvhima kwakadzika-gungwa
Iyo snipe eel ihove yakadzika-mugungwa inogara munzvimbo ine gomba regungwa. Ine muviri murefu, mutete nemhino ine mazino akapinza. Snipe eel inoshandisa mhino yayo ine mazino kubata hove diki nemhuka dzisina mutsipa mumvura ine rima, inotonhora kwainogara.
The Saber-Toothed Deer: Mhuka yekare ine mazino emhino
Nondo ine mazino esaber imhando yakatsakatika yemhembwe yaigara panguva yePleistocene epoch. Yaiva nemazino emhungu marefu akakombama ayo aibuda mushaya yayo yepamusoro, zvichiita kuti itaridzike ine mazino akapfava. Zvakadaro, yaivewo nemazino madiki aive pamhino dzayo, anogona kunge akashandiswa kuratidza kana kurwa.
Sei dzimwe mhuka dziine mazino pamhuno?
Mazino pamhuno magadzirirwo akashanduka mumhuka dzakasiyana nekuda kwezvikonzero zvakasiyana. Mune zvimwe zviitiko, inogona kushandiswa kuvhima kana kudzivirira, nepo mune dzimwe inogona kushandiswa kutaurirana kana kushamwaridzana zvinangwa. Dzimwe mhuka, senge nyeredzi-nosed mole, dzinoshandisa mazino emhino yavo kutsvaga uye kuona mhuka, nepo vamwe, senge narwhal, vanozvishandisa kukwezva vakaroorana kana kuratidza hutongi hwavo.
Mhedziso: Kunakidza kuchinjika muumambo hwemhuka
Mazino pamhino angaratidzika kuva echienzi kwatiri, asi anongova muenzaniso mumwe wemichina yakawanda inofadza yakashanduka-shanduka mumhuka. Kubva panhovo yenzou kusvika kumazino akapinza enzou, kuchinja uku kunoita zvinangwa zvakakosha pakurarama nekubereka kwemhuka. Nekudzidza aya akasiyana maficha, tinogona kuwana kunzwisisa kuri nani kwekuti mhuka dzakajairana sei nemhoteredzo yadzo nekufamba kwenguva.
