Maruarua ke liphoofolo tse anyesang tsa sehlopha sa li-cetacean, hammoho le li-dolphin, li-porpoise, maruarua a sperm le maruarua a melomo. Leha ho le joalo, ho fapana le tse ling, maruarua ke liphiri. Hona ho bolela hore ba se na meno, tšobotsi e amang haholo lijo tsa bona.
Joalokaha u tla bona, lijo tsa maruarua li ipapisitse le liphoofolo tse nyane haholo, ka hona li ja tse ngata haholo. Na u batla ho tseba hore na liphoofolo tsee tse thata ke bo mang? Kahoo tsoela pele ho bala! Sehloohong sena ke PeritoAnimal, re tla u joetsa seo leruarua le se jang.
mefuta ea maruarua
Ho biology, lentsoe whale le sebelisoa feela bakeng sa lelapa la balénidos. Leha ho le joalo, colloquially, tse ling tse ngata tsa cetacean li tsejoa e le maruarua:
- Balénidos: Ke liphiri (li-whale tse felletseng) 'me li fepa ka ho sefa. Sehlopha sena se kenyelletsa maruarua a nepahetseng le leruarua la Greenland.
- li-balenopterids kapa li-rorquais: le tsona ke li-whale. Har'a tsona ke phoofolo e kholo ka ho fetisisa lefatšeng, leruarua le putsoa le leruarua le tsebahalang haholo.
- Lingoliloeng kapa maruarua a maputsoa: ke li-odontocetes (maruarua a meno a maoto) joalo ka li-dolphin le tse ling tsa cetacean.
Sehloohong sena, re tla bua ka "maruarua a qetellang" ho kenyeletsoa le li-rorquais. Ho tseba phoofolo ena hantle, re khothaletsa hore o bale sengoloa ka mefuta ea leruarua.
ho fepa leruarua
Ho fepa ka leruarua ho ipapisitse le mokhoa oa ho sefa. Bakeng sa sena, li na le likarolo tse tsejoang e le mapheoana a tsoang mohlahareng o kaholimo (joalo ka meno a rona). Tsena ke letoto la likhoele tse ka bapisoang le bristles e brashi.
Ha li fumana lijo, liphoofolo tsena li bula mehlahare ea tsona e meholo 'me lijo le metsi li kena ka hanong. Hamorao, sutumelletsa maleme a bona marulelong a melomo ea bona, ho tloha mokokotlong ho ea molomong, ha ho boloka molomo o batla o koetsoe. Kahoo, ka lebaka la mapheoana a teng, li etsa hore metsi a tsoe, li siea lijo li qabeletsoe ka lehanong la molomo. Qetellong, li koenya lijo le lintho tse ling tse litšila tse ka bang teng ka leoatleng, tse kang lipolasetiki.
seo leruarua le se jang
Joale ha re se re tseba ho feta moo ka hore na liphoofolo tsena li fepa joang, ehlile o ntse o ipotsa hore na maruarua a ja eng. Le ha lijo li ipapisitse le libaka tseo ba leng ho tsona, re ka bua ka lijo tse tloaelehileng bakeng sa bona kaofela: the plankton. Hantle-ntle ke eng? Re tla bona!
Plankton ke eng?
Plankton ke pokello e nyane haholo ea lintho tse phelang tse emisitsoeng ka metsing. Tse ling tsa tsona ke:
- Baktheria.
- Basireletsi.
- Meroho (phytoplankton).
- Liphoofolo (zooplankton).
Ho fepa ka leruarua ho ipapisitse le karolo ea hoqetela, ke hore, ba joalo diphoofolo tse jang nama.
polokelo ea liphoofolo
The zooplankton kenyeletsa diphoofolo tse nyane haholo tse jang litho tse ling tsa plankton. Ke batho ba baholo ba li-crustaceans, joalo ka krill kapa copepods, le liboko tsa liphoofolo tseo, ha li phethela kholo ea tsona, li lulang botebong ba leoatle.
Krill - lijo tsa mantlha tsa maruarua
Re bitsa krill li-crustacean tse nyane tse atisang ho bonahala tse phelang maoatleng a lefatše. Liphoofolo tsena lia theha lihlopha tsa likete le likete tsa batho ka bomong eo e ka namela bakeng sa limaele. Ka lebaka lena, ke tsona motheo oa lijo tsa maruarua le liphoofolo tse ling tse ngata tse jang liphoofolo tsa leoatleng.
li-copepods tsa planktonic
Li-crustaceans tse ling tse phethang karolo ea bohlokoa ketaneng ea lijo tsa metsing ke li-ploptonic copepods. Bao li-crustaceans li ka metha ka tlase ho limilimithara hape ke lijo tsa mantlha bakeng sa maruarua le liphoofolo tse ling tse ngata tsa leoatleng.
liphoofolo tse ling tse nyane
Ntle le moo, re ka fumana ho zooplankton mekhahlelo ea bacha ea litlhapi le liboko tse ling ea liphoofolo tse kang liponche, likorale, echinoderms, li-molluscs ... Liphoofolo tsena kaofela li ba tse "ikemetseng" tsa plankton ha li se li le batho ba baholo.
Lijo Tse Ling Tsa Whale
Har'a lijo tsa maruarua a mang, joalo ka rorquais, ho na le tse ngata litlhapi tse shoal. Sena se lumella linatla tsa leoatle ho ja litlhapi tse makholo ka ho loma hanngoe.
Maruarua a ja litlhapi life?
Tse ling tsa litlhapi tseo e leng karolo ea lijo tsa leruarua ke:
- Capelin (malotusmamello).
- Khoutu ea Atlantic (gadusmorhua).
- Halibut (Reinhardtiussehlakoana).
- Herring (Sehlopha spp.).
Qetellong, squid le eona ke karolo ea lijo tsa maruarua a mang. Mohlala, phoofolo e kholo ka ho fetisisa lefatšeng, leruarua le leputsoa, hangata e theohela mokatong oa leoatle ho ea batla mahlako a squid.
ho shebella leruarua
Maruarua a falla haholo ho ea batla lijo. Hlabula li fallela metsing a batang moo lijo li leng ngata. Ha serame se fihla 'me palo ea lijo e fokotseha, li khutlela metsing a futhumetseng, moo li kopanang le ho ikatisa teng.
Tlhahisoleseling ena eu lumella ho tseba linako le libaka tse ntle bakeng sa ho shebella leruarua. Ha re boneng mehlala e meng:
- Hloahloa Valdes (Argentina): ke sebaka se hantle ho bona aleia-franca-austral (Eubalaenaaustralis).
- Bahia ballena (Costa Rica): leruarua le rata ho ea metsing ana ho ea kopana. Mona ho ka khonahala ho boloka li-dolphin, mantas le lishaka ...
- Baja California (Mexico): ke sebaka se setle ka ho fetisisa sa ho bona maruarua a maputsoa, leha ho tloaelehile ho bona leruarua le leputsoa.
- Lihlekehleke tsa Canary. Ho khonahala ho bona mefuta eohle ea li-rorquais hape le maruarua a melomo, maruarua a sperm le orcas.
- Kou ea Glacier (Canada): Ke sebaka se tsebahalang haholo bakeng sa ho shebella maruarua.
- Monterey Bay, California(U.S): Lehlabuleng le ka hoetla, leruarua le leputsoa le ka bonoa koung ena. Hape hoa khonahala ho shebella maruarua a maruarua, maruarua a nepahetseng, maruarua a minke ...
Ho na le libaka tse ling tse ngata moo u ka bonang bokhabane ba li-cetacean tsena. Leha ho le joalo, re u khothaletsa ho etsa joalo ka hloko, ntle le tšusumetso e nyane kamoo ho ka khonehang boits'oarong le libakeng tseo u lulang ho tsona.
Haeba u batla ho bala lingoliloeng tse ling tse tšoanang le Leruarua le ja eng?, Re khothaletsa hore o kenye karolo ea rona ea Lijo tse leka-lekaneng.
