Asalka dhammaan noolaha meeraha meeraha ka dhacay deegaanka biyaha. Intii lagu jiray taariikhda kobcinta, naasleyda ayaa is -beddelaysay oo la jaanqaadayay xaaladaha dhulka dushiisa ilaa, dhowr milyan oo sano ka hor, qaar ka mid ah ayaa ku soo noqday inay dhex galaan badaha iyo webiyada, iyagoo la qabsanayay nolosha xaaladahaas.
Maqaalkan PeritoAnimal, waan ka hadli doonaa naasleyda biyaha, oo si fiican loogu yaqaan naasleyda badda, maadaama ay ku jirto badaha ay ku noolyihiin tirada ugu badan ee nuucan ah. Ogow sifooyinka xayawaankan iyo tusaalooyinka qaarkood.
Astaamaha naasleyda biyaha
Nolosha naasleyda biyaha ku jirta aad bay uga duwan tahay tan naasleyda dhulka. Si ay ugu noolaadaan deegaankan, waa inay yeeshaan astaamo gaar ah inta ay ku guda jiraan horumarkooda.
Biyuhu waa dhexdhexaad aad uga cufan hawada, marka lagu daro, waxay bixisaa iska caabin weyn, taas oo ah sababta naasleyda biyuhu u leeyihiin jir aad u hydrodynamic, taas oo u saamaxaysa inay si fudud u dhaqaaqaan. horumarinta ee baalal Si la mid ah kuwa kalluunku waxay u taagan yihiin isbeddel weyn oo qaabdhismeed, kaas oo u oggolaaday inay kordhiyaan xawaaraha, toosiyaan dabaasha iyo isgaarsiinta.
Biyuhu waa dhexdhexaad oo nuugaya kuleyl aad uga badan hawada, sidaa darteed naasleyda biyaha ayaa leh lakab qaro weyn oo baruur ah hoosteeda maqaar adag oo adag, taas oo ka ilaalinaysa inay ka baxaan khasaarihii kulaylkaas. Intaas waxaa sii dheer, waxay u adeegtaa ilaalin marka ay ku nool yihiin aagagga qabow ee meeraha. Naasleyda badda qaarkood waxay leeyihiin dhogor sababta oo ah waxay qabtaan hawlo muhiim ah oo ka baxsan biyaha, sida taranka.
Naasleyda badda oo, xilliyada qaarkood ee noloshooda, ku nool qoto dheer, waxay soo saareen xubno kale si ay awood ugu yeeshaan inay ku noolaadaan mugdiga, sida sonar. Dareenka aragga ee hab -nololeedyadani waa mid aan waxtar lahayn, maadaama iftiinka qorraxdu uusan gaarin qoto dheerkan.
Sida naasleyda oo dhan, xayawaankan biyaha leh waxay leeyihiin qanjirro dhidid ah, qanjidhada naasaha, kuwaas oo caano u soo saara ubadkooda, oo uurjiifka ku haya jidhka gudihiisa.
Neefta naasleyda biyaha
naasleyda biyaha u baahan tahay hawo lagu neefsado. Sidaa darteed, waxay ku neefsadaan hawo aad u badan waxayna ku hayaan sanbabada muddo dheer. Markay quustaan neefsashada kadib, waxay awoodaan inay dhiigga u wareejiyaan maskaxda, wadnaha iyo muruqyada qalfoofka. Muruqyadaadu waxay leeyihiin tiro badan oo ah borotiin la yiraahdo myoglobin, oo awood u leh inay urursadaan xaddi badan oo oksijiin ah.
Habkan, xayawaanka biyuhu waxay awoodaan inay sii joogaan wakhti aad u badan iyagoo aan neefsan. Kutubta Dhallinyarada iyo Dhallaanka ma laha awooddan horumarsan, markaa waxay u baahan doonaan inay neefsadaan in ka badan kooxda inteeda kale.
Noocyada naasleyda biyaha
Inta badan noocyada naasleyda biyaha ku nool waxay ku nool yihiin deegaanka badda. Waxaa jira saddex amar oo naasleyda biyaha ah: cetacea, carnivora iyo serenia.
amarka cetacean
Sida ay u kala horeeyaan cetaceans, noocyada ugu badan ee matala waa nibiriyada, dolphins, nibiriyada shahwada, nibiriyada dilaaga ah iyo baafiyaha. Cetaceans -ku waxay ka soo baxeen nooc ka mid ah xakamaynta dhulalka carnivorous in ka badan 50 milyan oo sano ka hor. Amarka Cetacea wuxuu u qaybsan yahay saddex hoosaad (midkoodna baaba'ay):
- archaeoceti: xayawaanka dhulka afargeeslaha ah, awoowayaasha cetaceans -ka hadda jira (hore u baaba'ay).
- Dahsoon: nibiriyada fin. Waa xayawaanno hilib -laawe ah oo aan ilko lahayn oo qaata biyo aad u tiro badan kuna shaandheeya fin -ka, iyagoo ka soo qaada kalluun ku xaniban carrabkooda.
- odontoceti: Tan waxaa ku jira dolphins, nibiriyada dilaaga ah, xashiishyada iyo siibadaha. Waa koox aad u kala duwan, inkasta oo dabeecaddeeda ugu weyni ay tahay joogitaanka ilkaha. Kooxdan waxaan ka heli karnaa Dolphin casaan (Inia geoffrensis), nooc ka mid ah naasleyda biyaha biyaha macaan leh.
amarka hilibka
Amarka hilibka, ayaa lagu daray shaabadaha, libaaxyada badda iyo walxaha, inkasta oo otters -ka badda iyo orso -dabayshu ay sidoo kale ku jiri karaan. Kooxdan xayawaanka ah waxay soo ifbaxday qiyaastii 15 milyan oo sano ka hor, waxaana la rumeysan yahay inay si dhow ula xiriirto shaarubaha iyo orso (orso).
Siren siren
Amarka ugu dambeeya, seeriga, waxaa ku jira digongs iyo manatees. Xayawaankani waxay ka soo baxeen tetiterios, xayawaanno aad ugu eg maroodiyaal soo baxay qiyaastii 66 milyan oo sano ka hor. Dugongs waxay degan yihiin Australia waxayna maamulaan Afrika iyo Ameerika.
