Ho puruma ha tsona ho kang ha tau ho rehile litau tsa leoatle lebitso la tsona. Libatana tse matla li lula leoatleng 'me li ikamahanya hantle le bophelo ka metsing.
litsobotsi
Litau tsa leoatle li shebahala joang?
Litau tsa leoatleng ke tsa mofuta oa li-carnivores 'me moo ke tsa lelapa la liqibi tse nang le litsebe. Ba theha leloko-sehlopha sa Otariini ka mefuta e tsheletseng e fapaneng.
Mmele wa tsona o molelele mme maoto a ka pele le a ka morao a fetoha mapheo. Hlooho e nyane e nang le nko e kgutshwane e dula hodima molala o mokgutshwane, o matla.
Ho fapana le liqibi, litau tsa leoatleng li na le li-pinna tse nyenyane lihloohong tsa tsona 'me maoto le matsoho a tsona a ka morao a malelele haholo. U ka boela ua li mena ka pele tlas'a mpa ea hau. Li khona ho tsamaea ka potlako le ka boqhetseke ho feta naheng ho feta liqibi.
Tse tona tsa mefuta eohle ea li-sea lion li kholo haholo ho feta tse tšehali. Ha li ema holim'a mapheo a tsona a ka pele, li-specimens tse kholo ka ho fetisisa li feta limithara tse peli ka bolelele. Tse tona li na le moetse ’me ho puruma ha tsona ho utloahala eka ke ha tau ea sebele.
Boea ba litau tsa leoatleng bo sootho bo lefifi, bo teteane haholo, 'me bo leleka metsi, 'me bo na le moriri oa kutu le moriri o lebelang. Hobane undercoat e ntle e batla e le sieo ka ho feletseng, e lutse haufi le 'mele. Mafura a teteaneng, a bitsoang "blubber", a tloaelehile. O sireletsa liphoofolo metsing a batang.
Tau ea leoatleng e lula hokae?
Litau tsa leoatle li hlaha lebopong la Pacific la Amerika Leboea, maoatle a Pacific le Atlantic Amerika Boroa, ho potoloha Lihlekehleke tsa Galapagos, le mabopong a Australia le New Zealand. Litau tsa leoatle ke libōpuoa tsa leoatle 'me li lula haholo-holo mabōpong a majoe. Leha ho le joalo, li ea lebōpong ho ea nyallana, li tsoala le ho hōlisa malinyane.
Ho na le mefuta efe ea litau tsa leoatleng?
Mefuta e tsebahalang haholo ke litau tsa leoatleng tsa California (Zalophus californianus). Li phela lebōpong le ka bophirimela la Amerika Leboea ho tloha Canada ho ea Mexico, ke litau tse nyenyane le tse bobebe ho feta tsohle tsa leoatle 'me nko ea tsona e telele ebile e tšesaane ho feta mefuta e meng. Tse tona li hola ho fihla ho 220 centimeters, tse tšehali ho fihlela ho 170 cm ka bolelele.
Tse matla ka ho fetisisa ke litau tsa leoatleng tsa Steller ( Eumetopias jubatus ). Tse tona li bolelele ba limithara tse tharo le halofo 'me boima ba tsona bo feta tone, tse tšehali li lekanya lisenthimithara tse 240 feela le boima ba lik'hilograma tse 300. Ba lula haholo-holo mabopong a Pacific leboea ho Asia le Amerika Leboea.
Litau tsa leoatleng tsa New Zealand (Phocarctos hookeri) le tsona li batla li le nyane: tse tona li bolelele ba lisenthimithara tse 245, tse tšehali li fihla ho 200 centimeters. Ba lula lihleke-hlekeng tse ka boroa ho Antarctic ho potoloha New Zealand le mabōpong a Sehlekehlekeng se ka Boroa sa New Zealand.
Litau tsa leoatle tsa Australia (Neophoca cinerea) li lula haholo lihlekehlekeng tse haufi le mabopo a bophirima le boroa ho Australia. Tse tona li fihla ho 250 centimeters, tse tšehali ho fihlela ho 180 cm. Litau tsa leoatle tsa Amerika Boroa, tse tsejoang hape e le li-mane seal (Otaria flavescens), li lula lebopong la Pacific Amerika Boroa ho tloha Peru ho ea Tierra del Fuego le lebopong la Atlantic ho tloha ntlheng e ka boroa ho ea boroa ho Brazil. Tse tona li bolelele ba 250 centimeters, tse tšehali ke 200 centimeters.
Joalokaha lebitso la bona le bontša, litau tsa leoatle tsa Galápagos li lula Leoatleng la Pacific lebōpong la Lihlekehleke tsa Galapagos lik'hilomithara tse ka bang 1000 ka bophirimela ho Ecuador. Tse tona li hola ho fihla ho lisentimitara tse 270, tse tšehali li bolelele ba lisenthimithara tse 150 ho isa ho tse 170 feela.
Litau tsa leoatle li na le lilemo tse kae?
Ho itšetlehile ka hore na ke mofuta ofe, litau tsa leoatleng li phela lilemo tse 12 ho isa ho tse 14, empa liphoofolo tse ling li ka phela lilemo tse ka bang 20.
Itšoare hantle
Litau tsa leoatle li phela joang?
Litau tsa leoatleng li ikamahanya hantle le bophelo ba maoatleng a batang: Ka 'mele ea tsona e bonolo le maoto a fetotsoeng mapheo, li khona ho sesa ka bokhabane le ka bokhabane 'me li ka fihla lebelo la lik'hilomithara tse 40 ka hora metsing.
Mafura a teteaneng, e leng mafura, a sireletsa liphoofolo metsing a leoatle a batang. Haeba ho bata haholo, li-sea lion li ka boela tsa thefula phepelo ea mali likarolong tse ka ntle tsa 'mele e le hore li se ke tsa lahleheloa ke mocheso le ho fola.
Ho feta moo, ka lebaka la ho ikamahanya le maemo a fapaneng a 'mele ea bona, ba khona ho qoela ho fihlela metsotso e 15 le botebo ba limithara tse 170: Ba khona ho boloka moea o mongata, mali a bona a tlama oksijene e ngata, 'me ha ba qoela, ho otla hoa fokotseha. e le hore 'mele o sebelise oksijene e fokolang. Li ka boela tsa koala linko tsa tsona ka thata ha li qoela.
Ka mahlo a tsona a sa boneng khanya, li bona hantle metsing a lefifi le a lerethe. Li sebelisa kutlo ea tsona e ntle haholo ea ho fofonela ho fumana tsela ea tsona ea ho potoloha naheng. Moriri oa bona oa kutlo litelung le hloohong o sebetsa e le litho tsa ho ama. Ho feta moo, litau tsa leoatle li sebelisa mokhoa oa echo-sounding: li ntša melumo tlas'a metsi 'me li itšetlehile ka molumo oa tsona.
Le hoja li-sea litau li nkoa li le mabifi, li lihlong ha li le naheng ’me li atisa ho baleha ha li bona batho. Ha tse tšehali li e-na le malinyane, li a sireletsa ka matla haholo. Tabeng ea litau tsa leoatle, tse tona, ke hore, tse tona, li boloka liphatsa tsa lefutso tseo li li sireletsang ka matla khahlanong le liphoofolo tse tona.
