Kunezigidi zezinhlobo de peces olwandle kanye nezindlela eziningi zokubhukuda ngayinye ngayinye. Kukhona abangazi kahle ukubhukuda, abanye ababhukuda ngendlela engavamile kanti abanye ijubane labo liyamangalisa. Namuhla sizokhuluma ngenhlanzi indlela yayo yokubhukuda imangalisa ngempela. Imayelana neseyili. Ngomphetho wayo ohlukile wesigaxa sangemuva ngobukhulu obukhulu, le nhlanzi ingabhukuda ngokushesha okukhulu ifuna inyamazane yayo noma ibalekele izilwane eziyizingelayo.
Uma ufuna ukwazi konke okuphathelene nale nhlanzi, qhubeka ufunde 🙂
Izici ze-Sailfish
I-seilfish, enegama lesayensi Ama-albicans e-Istiophorus, yatholwa okokuqala ngo-1792 futhi ithathwa njengenhlobo evela e-Atlantic Ocean. Kuyaziwa nangokuthi izinhlanzi zasolwandle. Uyacabangela enye yezinhlanzi ezinhle kakhulu esingakuthola ezilwandle nasolwandle emhlabeni jikelele.
Kukhona okunye okungaphansi okuhlala olwandle lwaseNdiya nasePacific futhi kubizwe I-Istiophorus platypterus. Yomibili le mindeni inemibala eluhlaza okwesibhakabhaka noma empunga nesisu esimhlophe. Izinhlobo ze-Atlantic zincane.
Enye into eyingqayizivele yale nhlanzi impumulo yayo. Inesimo esingajwayelekile, sifinyelela iphuzu. Ifana ne-saber ebukhali. Lapho le nhlanzi isebenza, kuyamangaza ukuthi ikwazi kanjani ukubhukuda ngejubane eliphezulu ifuna inyamazane yayo. Ngenxa ye-morphology yayo, inganqamula emanzini kalula okungavamile. Ngakho-ke, ingafinyelela ngesivinini esikhulu.
I-dorsal fin yokuqala iyingxenye eyinhloko eyenza ihluke kwezinye de peces, enemisebe ephakathi kuka-37 no-49. I-dorsal fin yesibili incane futhi inemisebe eyisithupha noma eyisishiyagalombili kuphela. Umsila uyisici esibalulekile owusebenzisayo ukuze ufinyelele isivinini esikhulu njengoba uhlanganiswe ne-caudal peduncle enamandla futhi enamandla.
Ungathola izibonelo zeseyili enesisindo esingamakhilogremu ayi-100. Into ejwayelekile kakhulu ukuthi azungeze ama-50 kg.
Habitat
Le nhlanzi ihlala emanzini angenhla olwandle. Abavamisile ukuhlala ezinzulwini futhi bahlala bekhetha amanzi afudumele futhi afudumele. Endaweni lapho zisatshalaliswa khona, kulula kakhulu ukuthola isisulu sazo. Ngenxa yejubane ezihamba ngalo, umsebenzi wazo wokuthola ukudla awunzima kakhulu.
I-Atlantic sefish iyahlukahluka ngokuya ngamazinga okushisa kwamanzi futhi kwezinye izimo izimo zokuqondisa namandla omoya. Emkhawulweni wobubanzi bayo (enyakatho naseningizimu) ibonakala kuphela phakathi nezinyanga ezifudumele, ngoba ithanda amanzi afudumele. Izinguquko endaweni yazo yokuhlala ikakhulukazi zibangelwa ukufuduka kwesisulu sazo siye kwezinye izindawo. Ngakho-ke, ukuze baqhubeke nokudla, kufanele bahambe.
Ngokuvamile zitholakala ezindaweni ezifudumele neziphezulu ngaphezu kwe-thermocline. Lapho kufanele ifuduke, ikwenza lokho emanzini asondele kakhulu ogwini. Izinga lokushisa elifanele liphakathi kuka-21 no-29 degrees. Kwezinye izimo, kuye kwatholakala izibonelo zentsha de peces behamba ngomkhumbi oLwandle iMedithera abalahlekile phakathi nohambo lwabo lokufuduka.
Ngakolunye uhlangothi, inhlanzi yase-Indian-Pacific ngokuvamile itholakala emanzini apholile nasendaweni eshisayo yazo zonke izilwandle zomhlaba. Ukusatshalaliswa kwayo kutropical, kepha kungatholakala nasezindaweni ezisenkabazwe. Lezi zinhlobo zitholakala ezifundeni ezisogwini ezinamazinga okushisa aphakathi nendawo, yize zingatholakala nasezindaweni eziphakathi nolwandle. Ziyizinhlobo ze-epipelargic. Lokhu kusho ukuthi bachitha iningi lempilo yabo yabantu abadala endaweni ephezulu ye-thermocline.
Ukudla
Le nhlanzi idla ngokuphelele futhi ibhekwa njengesinye sezilwane ezinamakhono kakhulu ezilwandle. Akungabazeki ukuthi amanzi ashesha kakhulu kunawo wonke afudumele futhi apholile.
Ngokuvamile idla ama-squid, ingwane, tuna kanye nezinhlanzi endizayo. Ingasebenzisa uqhwaku lwayo ukuze ikhiphe amaseli de peces kuso sonke isikole futhi ngale ndlela kubenza babe sengcupheni yokubanjwa. Ziyakwazi ukutshuza kuze kufike kumamitha angama-30 ukujula, kodwa zincamela ukwenza lokho eduze nangaphezulu ukuze zizuze ekukhanyeni kwelanga. Itholakala eduze nemiphetho ye-coral ukuze ibe nombono obanzi wendawo futhi ikwazi ukuvala inyamazane yayo ekhoneni.
Ukuziphatha
I-seilfish iyinhlobo eyedwa (yingakho itholakala kalula ngokufuduka okuqhubekayo ifuna inyamazane). Kuyaqabukela ukuzibona zingamaqembu, yize kwesinye isikhathi zingabonakala ngamaqembu amancane ukwenza lula ukuzingela.
Luhlobo oluhlela futhi luhlole indawo kuqala ngaphambi kokuqalisa ukuzingela ukugwema izithiyo ezingaba khona.
Abesilisa nabesifazane banokuziphatha okufanayo, bezungeze inyamazane nokuphoqa isikole ukuthi sivalwe. Ama-thrush ayashesha futhi anembile, ngakunye kwandulelwa ukuthunyelwa okumangazayo kwe-dorsal fin, okungaphezulu kokuphinda kabili iphrofayili yomzingeli.
Ukuzala
Ukukhiqizwa kabusha kwe-seilfish kunokuphikisana okuningana. Insikazi izala kaningi ngonyaka ofanayo. Indawo abakhetha ukuyizalela imvamisa iyindawo lapho izinga lokushisa lizungeze ama-26 degrees Celsius. Imvamisa bakwenza ngasogwini. Ngokubeka ngakunye okwenziwa ngowesifazane ibeka amaqanda angaphezu kwesigidi aphonswa eceleni. Eyeduna, uma amaqanda esekhishiwe, ngokushesha ivundisa iningi lamaqanda.
Kusukela emaqandeni aphethwe ukuvundiswa, kuphuma amachwane amancane ahlala entanta phezulu, abe yizisulu ezilula zezilwane ezizingelayo. Ngakho-ke, emaqanda ayisigidi akhululwa ngowesifazane, ambalwa kuphela akwazi ukusinda ukuze akhule abe ngabantu abadala.
Amafry amancane anokukhula okusheshayo ngokweqile, ngakho-ke, uma bekwazi ukusinda esigabeni sokuqala lapho beyinyama entsha yezilwane ezidla ezinye, bazokwazi ukufinyelela esigabeni sabo sabadala. Amaphiko abo ithuthukiswe ngokuphelele lapho zifika ngamasentimitha amahlanu ubude.
Izinyanga ezizala kakhulu ziphakathi kukaMashi no-Okthoba. Lapho izinhlanzi zingabantu abadala, izitha zazo ezivame kakhulu izinhlanzi ezinkulu njengoshaka.
Ngalolu lwazi ungafunda kabanzi mayelana nenye yezinhlanzi ezinhle kakhulu olwandle.
