Isilwane esisheshayo ingulule, inyoni eshesha kunazo zonke iyinkozi yokhokho, inhlanzi eshesha kakhulu - lowo ngumbuzo nombuzo. Ibizwa izinhlanzi zasolwandle, futhi kungaye okuzoxoxwa ngaye ngokuqhubekayo.
Isikebhe senhlanzi
Incazelo kanye nezici zesikebhe senhlanzi
Umgijimi oshesha kakhulu phakathi kwezinhlanzi ungowomndeni we-sailfish, ama-perchiformes. Ubude besilinganiso esilinganiselwe cishe siyi-3-3.5 m, isisindo singaphezu kuka-100 kg. Ngonyaka owodwa, izikebhe zesikebhe ziba nobude obungu-1.5-2 m.
Isidumbu senhlanzi sinesimo se-hydrodynamic futhi simbozwe yimifantu yamadlambi amancane anama-serrated, eduze kwawo amanzi amile. Lapho kuhamba, uhlobo oluthile lwefilimu lwamanzi luzungeza inhlanzi, futhi ukungqubuzana kwenziwa phakathi kwezendlalelo ezahlukahlukene zamanzi, kudlula isikhumba sesikebhe, kuyilapho inani laso lesilinganiso liphansi kakhulu.
Mayelana nombala, iyefana nezinhlanzi eziningi ze-pelagic esikebheni sokuhamba. Indawo engemuva imnyama ngombala oluhlaza okwesibhakabhaka, isisu sikhanya nge-metallic sheen. Izinhlangothi zinombala onsundu, nazo ziluhlaza okwesibhakabhaka.
Izikebhe zesikebhe zithanda ukugxumela emanzini
Kuyo yonke ingxenye eseceleni ukusuka ekhanda kuye emsileni, umzimba umbozwe amachashazi amancane aluhlaza okwesibhakabhaka, ahambisana nephethini eqinile yejometri ngendlela yemivimbo eguqukayo.
Ukubheka esithombeni senhlanzi yesikebhe, Akunzima ukuqagela ukuthi yiziphi izici lo mhlali wasolwandle abizwa ngegama lakhe. Isiphetho sayo esikhulu semhlane sangemuva sifana nokubanjwa kwemikhumbi yangenkathi ephakathi.
Ibaleka ngemuva kwekhanda emhlane wonke futhi ipendwe ngomthunzi we-ultramarine onamanzi, nawo onamabala amnyama amancane. Amanye amaphiko anombala onsundu.
Iseyili fin yenza imisebenzi eminingi ebalulekile. Nguye osiza izinhlanzi ukuthi zishintshe ngokuzumayo indlela yokuhamba lapho zibona ingozi noma esinye isithiyo. Ubukhulu bayo buphinda kabili ubukhulu bomzimba.
Umkhawulo ongaphezulu wenhlanzi yesikebhe
Ngokusho kwabanye ososayensi, ngesikhathi sokuhamba ngesivinini esikhulu useyili usebenza njengohlobo lokuzinza izinga lokushisa. Ngokusebenza ngamandla kwemisipha, igazi liyashisa, nephiko langemuva eliphakanyisiwe elinesimiso semithambo esithuthuke kahle kupholisa inhlanzi eshisayo, kuyivimbele ukuthi ingamane ibile.
Ngasikhathi sinye, izikebhe zesikebhe zinesitho esikhethekile sokufudumeza, ngosizo lwegazi elifudumele eligijimela ebuchosheni nasemehlweni ezinhlanzi, ngenxa yalokho isikebhe sibona ukunyakaza okuncane ukushesha kunanoma iyiphi enye inhlanzi.
Umkhawulo ongaba khona isivinini senhlanzi esikebheni semikhumbi ukusiza ukuthuthukisa izici ekwakhiweni komzimba. Kukhona inothi ekhethekile ngemuva kwezinhlanzi, lapho useyili uhlehliswa khona ngesivinini esikhulu. Izimpiko zangasese nezangasese nazo zifihliwe. Lapho igoqwe ngale ndlela, ukumelana kunciphisa kakhulu.
Imihlathi inokukhula okude, okuphezulu okufaka isandla ekuxakaneni. Ukuqina okungafanele ngenxa yokungabikho kwe-bubble yomoya nakho kuthinta isivinini.
Isikebhe senhlanzi sizingela izinhlanzi ezincane
Umsila onamandla wemisipha, ofana ne-boomerang, usiza inhlanzi ukuba iwele emanzini. Yize ukunyakaza kwayo okunganyakazi kungafani ngobubanzi obukhulu, kwenzeka ngemvamisa engakholeki. Amajika adonswe yizinhlanzi zesikebhe zifana nobuhle nobuchule obufana ne-aerodynamics yezindiza zesimanje.
Ngakho-ke bangasungula liphi ijubane izikebhe ezisheshayo zezinhlanzi? Kuyamangalisa - ngaphezu kwe-100 km / h. AbaseMelika benza ucwaningo olukhethekile ogwini lwaseFlorida futhi baqopha imininingwane yokuthi isikebhe sasibhukuda ibanga elingu-91 m ngemizuzwana emi-3, okulingana nejubane lika-109 km / h.
Ngendlela, umkhumbi-ngwenya oshesha kakhulu emlandweni, iSoviet K-162, awukwazanga ukuhamba kukholamu lamanzi ngokushesha kuno-80 km / h. Kwesinye isikhathi ungabona ukuthi inhlanzi yesikebhe ihamba kanjani kancane kancane ebusweni, ikhiphe isiphetho sayo esidumile ngaphezu kwamanzi.
Indlela yokuphila yezinhlanzi zasolwandle kanye nendawo yokuhlala
Izinhlanzi zesikebhe zihlala emanzini afudumele enkabazwe olwandle lwaseNdiya, lwe-Atlantic nolwePacific, atholakala oLwandle Olubomvu, iMedithera kanye nolwandle Olumnyama.
Lezi zinhlanzi zibonakaliswa ukufuduka ngezikhathi ezithile zonyaka, isikebhe senhlanzi yasebusika ikhetha ukusuka ezindaweni ezipholile ezisondele enkabazwe, futhi lapho kufika ukushisa kubuyela ezindaweni zayo zangaphambili. Ngokuya ngendawo, ababili babehlukaniswa phambilini izinhlobo zezinhlanzi zesikebhe:
- Istiophorus platypterus - ohlala e-Indian Ocean;
- Ama-albicans e-Istiophorus - ahlala engxenyeni esentshonalanga nasenkabeni yePacific.
Kodwa-ke, ezifundweni eziningi, ososayensi abakwazanga ukubona noma yikuphi ukwehluka kokuziphatha nofuzo phakathi kwabantu base-Atlantic nabasePacific. Ukuhlolwa kokulawulwa kwe-DNA ye-mitochondrial kuqinisekisile leli qiniso kuphela. Ngakho-ke, ochwepheshe bazihlanganise lezi zinhlobo ezimbili zaba munye.
Ukudla kwezinhlanzi zesikebhe
Ukudla kwezinhlanzi zasolwandle ngezinhlobo ze-pelagic zezinhlanzi ezincane zesikole. Ama-anchovies, ama-sardine, ama-mackerel, ama-mackerel, nezinye izinhlobo zama-crustaceans ziyingxenye ebalulekile yokudla kwakhe. Kuyathakazelisa ukuyibuka ukuthi inhlanzi yesikebhe ibukeka kanjani ngenkathi uzingela.
Ukuphishekela isikole sezinhlanzi, sifinyelela emashumini ezinkulungwane zabantu, sihamba njengesidalwa esisodwa, lesi sikebhe sihlasela ngejubane lombani, sishiya izinhlanzi ezincane zingenamathuba okuphila.
Inhlanzi yesikebhe ijaha inyamazane
Izikebhe ezisolwandle azizingeli zilandelana, kodwa ngemihlambi emincane, zishaya imihlathi yazo, ziyayithungatha inyamazane bese ziyishayela ziye ezingxenyeni ezingenhla, lapho ingekho indlela yokucasha. Ngezimpumulo zabo ezimise okomkhonto, balimaza izinhlanzi ezincane futhi babamba ngeshwa i-mackerel noma i-mackerel, esivele ikhathele amanxeba.
Kuvamile ukuthi isikebhe semikhumbi sihlabe izikebhe zokudoba zokhuni ngesiqu saso esibukhali futhi sidale umonakalo omkhulu nasezinsimbini zemikhumbi.
Ukuzaliswa kanye nempilo yezinhlanzi zesikebhe
Izikebhe zesikebhe zizala emanzini ashisayo nasenkabazwe ngasekupheleni kwehlobo - ekwindla yokuqala. Njengabanye abamele i-oda, lezi zinhlanzi zanda kakhulu. Ngenkathi eyodwa ephakathi nendawo, insikazi ingazalela amaqanda afinyelela ezigidini ezinhlanu ekuvakasheni okuningana.
I-Saviboat caviar incane futhi ayinamatheli. Iyazika emanzini angaphezulu futhi iyisibiliboco ezinhlotsheni eziningi zezinhlanzi, ukuze iningi lamaqanda nefusi elichanyuselwe linyamalale kungabikho noluncane emlonyeni wezilwane eziyingozi.
Isikhathi esinqunyiwe sempilo yesikebhe seminyaka engu-13 kuphela, inqobo nje uma singabi yizisulu zezilwane ezinkulu noma abantu. U-Ernest Hemingway, ezindabeni zakhe eziningi, unikeza imininingwane Incazelo yenhlanzi yesikebhe nezindlela zokubamba lesi sidlakela esinamandla.
Isikebhe sokudoba
Izincwadi zakhe, ezazisakazeke emhlabeni wonke ngezigidi zamakhophi, zenza ukukhangisa kwezinhlanzi "okuhle", abadobi bakhombisa intshisekelo emangalisayo yokubamba lolu hlobo.
Ngasogwini lwaseCuba, eHawaii, eFlorida, ePeru, e-Australia nakwezinye izifunda eziningi, ukudotshwa kwezikebhe ngukuzijabulisa okuthakazelisa kakhulu. EHavana, izwe lasekhaya lombhali oshiwo ngenhla, imincintiswano yama-anglers ibanjwa minyaka yonke.
ECosta Rica, imicimbi efanayo iphela ngokukhululwa kwezinhlobo ezibanjiwe olwandle, ngemuva kwesisindo nesithombe sememori. Ensimini yaleli zwe, izinhlanzi zesikebhe ziyavikelwa futhi ukudoba okungalawulwa akuvunyelwe. EPanama, lolu hlobo lubhalwe kuRed Book futhi ukubanjwa kwalo nakho akuvunyelwe.
Ukudoba isikebhe - umsebenzi othokozisayo ngitsho ne-angler ekhuthele. Izidlakela ezinamandla nezinobuhlakani zingadinisa noma ngubani. Babhala zonke izinhlobo zokuqubuka ngaphezulu kwamanzi, ngazo zonke izindlela ukumelana nesiphetho esingenakugwemeka.
Ukuthola ukuthi inhlanzi yesikebhe sesikebhe ithanda kanjani, akudingekile ukundiza uye kolunye uhlangothi lomhlaba. Ezindaweni eziningi zokudlela zamadolobha amakhulu unganambitha izitsha ezivela kule nhlanzi exotic, uma ufisa.
