Kukho izigidi zeentlobo de peces elwandle kunye neendlela ezininzi zokuqubha nganye nganye. Kukho abo bangakwaziyo ukudada kakuhle, abanye baqubha ngendlela engaqhelekanga nabanye abanesantya esimangalisayo. Namhlanje siza kuthetha ngentlanzi endlela yayo yokudada inomtsalane ngokwenene. Imalunga neseyelfish. Ngomphambili wayo oqhelekileyo onobukhulu obukhulu, le ntlanzi inokudada ngesantya esiphezulu xa ikhangela ixhoba layo okanye ibalekele iintshaba zayo.
Ukuba ufuna ukwazi yonke into enxulumene nale ntlanzi, qhubeka ufunde 🙂
Iimpawu zesailfish
I-sailfish, enegama lenzululwazi Istiophorus albicans, yafunyanwa okokuqala ngo-1792 kwaye ithathwa njengendidi evela kuLwandlekazi lweAtlantic. Kukwaziwa njengeentlanzi zasemarlin. Ngaba unolwazelelelo enye yeentlanzi ezintle kakhulu onokuyifumana kwiilwandlekazi nakwiilwandlekazi kwihlabathi liphela.
Kukho enye iindidi ezihlala kwiilwandle zaseIndiya nasePacific kwaye zibizwa I-Istiophorus platypterus. Zombini ezi ntsapho zinemibala eluhlaza okwesibhakabhaka okanye engwevu kunye nesisu esimhlophe. Iintlobo zeAtlantic zincinci.
Enye into ekhethekileyo yale ntlanzi ngumphunga wayo. Inobume obungaqhelekanga, obufikelela kwinqanaba. Ifana nesaber ebukhali. Xa le ntlanzi isebenza, iyachukumisa indlela edada ngayo ngesantya esiphezulu ikhangela ixhoba layo. Ngenxa ye-morphology yayo, inokucoca amanzi ngokulula okungaqhelekanga. Ke ngoko, inokufikelela kwisantya esikhulu.
I-dorsal fin yokuqala yinto ephambili eyenza ukuba yahluke kwezinye de peces, enemitha ephakathi kwama-37 nama-49. Iphiko lesibini lomqolo lincinci kwaye linemitha emithandathu okanye esibhozo kuphela. Umsila yinto esisiseko esetyenziswayo ukufikelela kwizantya eziphezulu kuba idityaniswe yi-caudal peduncle eyomeleleyo nenamandla.
Unokufumana iisampulu zentlanzi enobunzima obuziikhilogram ezili-100. Eyona nto iqhelekileyo kukuba zijikeleze i-50 kg.
Indawo yokuhlala
Le ntlanzi ihlala kulwandle oluphezulu. Abahlali bahlala ezinzulwini kwaye bahlala bekhetha amanzi ashushu afudumeleyo. Kwindawo apho zisasazwa khona, kulula kakhulu ukufumana ixhoba labo. Ngombulelo kwisantya abahamba ngaso, umsebenzi wabo wokufumana ukutya awukho nzima kakhulu.
I-Atlantic seilfish iyahluka ngokoluhlu lwazo ngokuxhomekeke kubushushu bamanzi kwaye kwezinye iimeko iimeko zendlela kunye namandla omoya. Kwindawo ezigabadeleyo zoluhlu lwayo (emantla nasemazantsi) kubonakala kuphela kwiinyanga ezifudumeleyo, kuba ikhetha amanzi ashushu. Utshintsho kwindawo ezihlala kuyo ikakhulu zibangelwa kukufudukela kwelinye ilizwe kwezinye iindawo. Ke ngoko, ukuze baqhubeke nokondla, kufuneka bahambe.
Zifumaneka ngokubanzi kwiindawo ezifudumeleyo neziphezulu ngaphezulu kwe-thermocline. Xa kufuneka ifuduke, yenjenjalo emanzini akufutshane nonxweme. Ubushushu obufanelekileyo buphakathi kwama-21 nama-29 degrees. Kwezinye iimeko, imizekelo yolutsha iye yafunyanwa de peces behamba ngesikhephe kuLwandle lweMeditera abaye balahleka ebudeni bohambo lwabo lokufuduka.
Kwelinye icala, i-Indian-Pacific seaffish ifumaneka ngokubanzi kumanzi ashushu kunye nakuma tropical olwandle lonke. Ukuhanjiswa kwayo kuyitropiki, kodwa inokufumaneka nakwindawo zeikhweyitha. Olu hlobo lufumaneka kuyo yonke imimandla eselunxwemeni yeendawo ezishushu eziphakathi, nangona zinokufumaneka nakwiindawo ezisembindini wolwandle. Ziintlobo zeepipelargic. Oku kuthetha ukuba bachitha uninzi lobomi babo babadala kwindawo ephezulu ye-thermocline.
Ukutya
Le ntlanzi itya kakhulu kwaye ithathwa njengenye yezona zilwanyana zinezilwanyana ezinobuchule elwandle. Alithandabuzeki elona libaleka kuwo onke amanzi ashushu afudumeleyo.
Idla ngokutya iskwidi, ingwane, ityhuna kunye neentlanzi ezibhabhayo. Inokusebenzisa umlomo wayo ukususa iiseli de peces zesikolo siphela kwaye ngale ndlela zibenza babe sesichengeni sokubanjwa. Ziyakwazi ukuntywila ukuya kuthi ga kwi-30 yeemitha ubunzulu, kodwa zikhetha ukwenza oko kufutshane nomphezulu ukuze zixhamle kukukhanya kwelanga. Ibekwe kufuphi nemiphetho ye-coral ukuze ibe nombono obanzi wendawo kwaye ikwazi ukufihla ixhoba layo.
Ukuziphatha
I-sailfish luhlobo oluhlala lodwa (yiyo loo nto kulula ukuba ufuduke ngokukhangela ixhoba). Kunqabile ukuzibona ngokwamaqela, nangona ngamanye amaxesha zinokubonakala ngokwamaqela amancinci ukulungiselela ukuzingela.
Luhlobo oluququzelela kwaye luvavanye umhlaba kuqala ngaphambi kokuqalisa ukuzingela ukunqanda imiqobo enokubakho.
Amadoda nabasetyhini banendlela efanayo yokuziphatha, ejikeleze ixhoba kunye nokunyanzela isikolo ukuba sivale iirenki. Ukugxotha kuyakhawuleza kwaye kuchanekile, nganye nganye yandulelwa kukumiswa okumangalisayo komqolo, okungaphezulu kokuphinda kabini iphrofayili yomzingeli.
Ukuveliswa kwakhona
Ukuveliswa kwakhona kweentlanzi zineempikiswano ezininzi. Imazi izala amatyeli aliqela kwakuloo nyaka. Indawo abakhetha ukuyizalela ihlala iyindawo apho ubushushu bujikeleze ama-26 degrees celcius. Bahlala bekwenza oko kunxweme. Ngalinye lokubeka elenziwa ngumfazi zibeka amaqanda angaphezu kwesigidi aphoswayo. Indoda, akuba amaqanda ekhululwe, kwangoko ifakela uninzi lwamaqanda.
Ukusuka kumaqanda akwaziyo ukuchumisa, kuphuma amantshontsho amancinci ahlala edada ngaphezulu, abe lixhoba elilula kumarhamncwa. Ke ngoko, kwizigidi zamaqanda ezikhutshwa ngumfazi, ambalwa kuphela akwazi ukuphila ukuze akhule abe ngabantu abadala.
Iifry ezisencinci zikhula ngokukhawuleza okukhulu, ukuba ziyakwazi ukusinda kwinqanaba lokuqala apho ziyinyama entsha kumarhamncwa, ziya kuba nakho ukufikelela kwinqanaba labo labantu abadala. Amaphiko azo iphuhliswe ngokupheleleyo xa zifikelela kwiisentimitha ezintlanu ubude.
Ezona nyanga zidala rhoqo ziphakathi kuka-Matshi no-Okthobha. Xa iintlanzi zingabantu abadala, ezona ntshaba zabo zixhaphakileyo ziintlanzi ezinkulu ezinje ngookrebe.
Ngolu lwazi ungafunda okuninzi malunga neyona ntlanzi intle kakhulu ezilwandle.
