Enye yezona ntlobo zentlanzi zihluke kakhulu I-hammerhead ukrebe. Intloko yayo imile okwehamile, nto leyo eyenza ukuba yaziwe ehlabathini lonke. Kodwa ngelishwa, kungenxa yokuba abantu bazibona kwiikhathuni, iimuvi, amaxwebhu, iifoto, iincwadi, njl. Enyanisweni, bambalwa kakhulu abaseleyo kangangokuba akunakwenzeka ukuba umbone ephila. Ukuba inyathelo alithathwa ngoku, lisenokunyamalala.
Kweli nqaku siza kukuxelela zonke iimpawu, indlela yokuphila, ukondla kunye nokuveliswa kwe-hammerhead shark.
Iimpawu eziphambili
Ihammerhead shark okanye iSphyrnidae luhlobo lokrebe oluhlala phantse kuzo zonke iilwandlekazi, kumanzi apholileyo okanye ashushu, ikakhulu kwiindawo eziselunxwemeni. Iindidi ezilithoba zehammerhead sharks ziyaziwa kwaye zihluka ngobukhulu ukusuka malunga nemitha e-1 ukuya kwi-6 yeemitha, apho unokulinganisa i-hammerhead enkulu.
Kodwa ngaphandle kwamathandabuzo, into eyenza esi silwanyana saduma kwaye sahluke kukuqhuma empumlweni yaso, eyathi yayithiya igama elithi 'hammerhead shark' ngenxa yokufana kwayo nohlobo oluthile lwemallet. I-Hammerheads ineempumlo ezinkulu kunabanye ookrebe kwaye amehlo abo abekwe kude, ebanika inkangeleko eyahlukileyo kakhulu.
Enye yeempawu zayo ezingaqhelekanga kukuba ihammerhead shark ineemvakalelo ezisi-7. Ukongeza kwizivamvo zabo zokuchukumisa, ukuva, ukujoja, ukubona, kunye nokungcamla, ookrebe banengqiqo enye ebavumela ukuba babone amaza aphindaphindiweyo abangelwa kukushukuma kweentlanzi, kunye nenye ingqiqo ebavumela ukuba babone amasimi ombane baze bafumane efihliweyo okanye efihliweyo. izinto ezifihlakeleyo.
Ngokungathandabuzekiyo sesinye sezona zilwanyana zinomtsalane ehlabathini, enomtsalane wokwenyani ebantwini, nokuba iboniswe kwi-aquarium okanye ukuyirhweba ngamaphiko ayo. Ibizintloni kubo into yokuba indoda ijonge kuye.
Inkcazo yeHammerhead Shark
Into yokuqala ebonakalayo eyenziwa ngukrebe we-hammerhead yintloko emile okwe-T, kwaye njengoko besenditshilo, iqhuma elinika igama likakrebe. Isizathu soku asicacanga, ngaphandle kwezifundo ezininzi eziye zagqiba kuphela ukuba yavela ngendlela yokuba ukubekwa kwamehlo ayo kunokuphucula umbono wezilwanyana.
Kanjalo, into ebalaseleyo malunga neentloko zeehammerheads kukuba zinombono we-360 °, nto leyo ethetha ukuba banokubona phezulu nasezantsi ngaxeshanye. Obu buchule bubavumela ukuba bafumane ukutya. Ookrebe be-Hammerhead banesakhiwo se-vertebral esivumela ukuhamba ngokufanelekileyo xa befuna ukutya.
Ezinye iimpawu zomzimba, umzekelo, "zineempumlo" kwinqanaba lokwandiswa kwentloko kunye namehlo amakhulu ekupheleni. Umlomo wayo mncinci xa uthelekisa nentloko yayo, nangona inamazinyo arhabaxa kwaye ibekwe embindini wentloko yayo.
Kananjalo banamaphiko ama-2 omqolo, elokuqala lilikhulu kunomnye. Ukongeza, umzimba wayo ubonisa umbala oluncedo owahlukileyo wokuzifihla kumhlaba wolwandle, kuba indawo ye-ventral ikhaphukhaphu ngombala ngelixa indawo yomqolo ingwevu okanye eluhlaza. Ngokuqhelekileyo ilinganisa phakathi kwe-0,9 kunye ne-6 yeemitha kwaye inobunzima phakathi kwe-300 kunye ne-580 yeekhilogram.
Indawo yokuhlala i-Hammerhead shark
Iindidi ezahlukeneyo zeehammerhead sharks zisenokufumaneka kumanzi apholileyo nakweleenjiko, ecaleni konxweme kunye neeshelufa zamazwekazi, phantse kwihlabathi liphela.
Eminye imizekelo ifunyenwe kwibhanti ye-mesopelagic, ukuya kutsho kubunzulu be-80 m. Eyona ndawo ixhaphakileyo yokuhlala idla ngokuba ziingqaqa ezingenzulwanga kwaye ngamanye amaxesha amanzi anetyuwa, nto leyo eyenza kube nzima ukuyifumana, nto leyo edibanisa into yokuba abalobi abaninzi bazingela amaphiko abo.
Ukondla nokuzala
Ihammerhead shark yinyama edla inyama edla ngokutya iindidi ezininzi zamaxhoba. Ukutya kwabo ziintlanzi ezinamathambo, isquid, ingwane neecrustaceans, kodwa eyona nto bayithandayo yimitha. Baza kutya abantu ngamaxesha athile.
Zizilwanyana ezidla ngokuzingela zodwa xa kufikelelwa ekufumaneni ukutya. Ngokusebenzisa i-electroreceptors kunye nentloko, Unokubona kwaye ubambe iibhothi zombane ezifihlwe kwisanti engezantsi.
I-Hammerhead sharks zintlobo ze-viviparous ezizala ukuhlala zincinci. Zidla ngokuzala kanye ngonyaka ngokuqhama kwangaphakathi, yaye inani lamantshontsho emazi lidla ngokunxulumana nobukhulu balo. Okukhona ubunzima nobude bakhe bukhulu, kokukhona uba mncinane.
Xa kufuneka zikhwelane, iqela lamadoda lithatha imazi lize lifake ikliphu kumbhobho wayo, ngaloo ndlela lidlulisela amadlozi ayo. Xa ikhulelwe, imazi igcina abantwana bayo ngaphakathi kangangeenyanga ezisi-8 ukuya kwezili-10, ibondla ngengxowa yomthubi. Emva kwexesha, i-12 ukuya kwi-50 encinci iyazalwa, i-18 cm ubude kunye neentloko ezithambileyo, ezingqukuva. Ufudo olusandul’ ukuqanduselwa alufumani ngqalelo yabazali, kodwa ngokufuthi luhlanganisana kumanzi afudumeleyo luze luhlale apho de lukhule ngcono kwaye lukwazi ukuzinyamekela.
Ukuziphatha kunye nezoyikiso
Nangona sisilwanyana esifumaneka sisodwa kwaye ngokwenene zizingela sodwa, luhlobo oluhlala ngokwamaqela, aquka ukuya kuma-500 amalungu. Kula maqela, ukrebe ngamnye uyinxalenye yentlalontle apho bohlulwe khona kwaye emisela ukongamela kwabo kwiqela.
Ngokobukhulu, Ubudala kunye nesondo, ii-hammerheads ziseka iqela labo leqela, apho bahlala khona imini yonke kude kube sebusuku. Akwaziwa ukuba kutheni ehlanganisana, kodwa kubonakala ngathi akwenza oko ukuze azikhusele kumarhamncwa amakhulu kwaye angawahlaseli xa ebonwa ehlala kunye.
Nangona le ndlela yokuziphatha, ezinye iindidi zeehammerhead sharks zihlala zifuduka ngexesha lasehlotyeni xa zisiya kumanzi apholileyo. Kwakhona, ezinye iintlobo zihlala bhetele kumanzi anzulu, ngelixa ezinye zikhetha ngaphantsi.
I-Hammerhead sharks ithathwa njengentlanzi eyingozi ebantwini, nangona eneneni ingekho ndlongondlongo. Uninzi lweengcebiso zehamile zincinci kakhulu kwaye azinabungozi.
Indoda ihlala isiya kuzingela kwaye iloba kungekuphela nje inyama yayo, kodwa kwanamaphiko kakrebe, adla ngokuxabiseka kurhwebo olumnyama.
I<em>hammerhead shark yongezwe kuludwe lwezilwanyana ezisengozini yokuphela yaye, ukuba akuthatyathwa manyathelo ngokukhawuleza, uya kuthelela uludwe lweentlobo eziye zatshatyalaliswa emhlabeni. Njengesiqhelo, eyona ngozi iphambili kukungakhathali kwabantu abayiloba ngokungakhethiyo ngenxa yamaphiko ayo kuphela, agqalwa njengento emnandi. Ayinguye kuphela ukrebe osengozini yokuphela, ekubeni ingwe ookrebe kunye ookrebe beenkunzi baye bongezwa kuLuhlu oluBomvu lwe-IUCN.
Ookrebe beHammerhead banokufikelela kubude obumalunga neemitha ezine. Kwaye banomkhuba owenza ukuloba kube lula njengoko bethanda ukuqubha ngokwamaqela, adla ngokuhlanganisana kwiindawo ezithile, njengeGalapagos neCosta Rica. Izikhephe zokuloba ziyantlitheka kuzo, zintlitheka kwindawo enabantu abaninzi beentlanzi, zinqumle amaphiko azo. Bayisebenzisela ukwenza isuphu eyaziwayo kulo lonke ilizwekazi laseAsia. Inxalenye yomzimba kakrebe ibekwe apho, inyama yakhe ayinaxabiso.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga ne-hammerhead shark kunye neempawu zayo.
